F8-x86_64 on the Acer Ferrari 3400LMi
1 Introduction
This document is primarily designed for my own records for future use. However,
it is always nice if it may help others to get started with Linux on their laptops.
The steps to get things to play on the Acer Ferrari 3400 Lmi are described here.
Most procedures are general and may be useful for other hardware as well.
! ! ! WARNING ! ! !
However, I must warn those of you that still enjoy the luxury of an independent
mind and free will. Stay away! Do not ever lay your hands on the Ferrari.
The same warning applies to the GNU/Linux software platform in general. It
was several years ago my self defense was totally broken.
The combination is truly devastating! I have noticed strange things happening to
me since I got My Precious...
Please feel free to comment on any topic or possible improvements in this
document.
1.1 Version
This is an updated version of this document. This time I have chosen to install
Fedora 8 x86_64, and many things has really changed to the better. The first
version dealt with FC4-x86_64, and there are no major changes for FC5-x86_64.
Consequently, if you are heading for FC4 or FC5 you probably want to have a
look at the previous version of this document. While some details may be specific
for Fedora, most stuff should translate to other distributions as well.
1.2 Quick reference guide
I've got all of the hardware working. Although, somethings need some extra
tweaks. A summary may be found in the table below

2 Installation
No special procedure is needed during the core installation of F8 x86_64.
Partition the hard drive as desired and install the components that you like.
However, some packages will make life easier when configuring your new laptop.
These are mentioned in the corresponding sections below and may be installed
afterwards.
2.1 Potential pitfalls
Depending on your setup there are some pitfalls you should know about.
2.1.1 Graphical installer
Fedora Core 5 installation and later runs without any problems, while Fedora
Core 4 should be started with:
# linux nofb
This tells the installation to disable the frame buffer so you may use the graphical
mode of the installer. Otherwise you will loose the display shortly after the
installation enters graphical mode. This only applies to FC4 and earlier.
2.1.2 Disk size
However, depending on your hardware you might notice a strange disk size
during the installation of F8. If you see a disk size less than expected you should
pass the kernel option libata.ignore_hpa=1 to the installation.
1. When you see the graphical boot screen, press tab.
2. Edit the boot command to look like:

F8-x86_64 on the Acer Ferrari 3400LMi
vmlinuz initrd=initrd.img libata.ignore_hpa=1
3 Hard drive
No hassle what so ever, but my own reflection is that the standard hard drive
does not match the “high end gear” profile of this laptop. When the laptop was
released 120 MB drives was the latest of the greatest and 100MB drives were off
the shelf goods in most stores. However, a smaller drive would have been ok at a
higher speed, at least 5400rpm.
3.1 Upgrading the drive
I am addicted to VMware and want extra of everything, size, speed, RAM, etc.
Thus, I have replaced the original Hitachi Travelstar 80 GB (4200rpm) drive with
a Seagate Momentus 160 GB (5400rpm, ATA/ATAPI-6, ST9160821A). What a
difference! The higher speed, as well as the higher storage density, pays off in far
better performance. Operating temperature is the same as for the original drive.
According to the smartmontools it runs at 40-48 °C during normal load with
peaks above 50 °C during heavy load. A highly recommended upgrade!
Depending on the hardware you might notice a strange disk size of your new
drive. If you just plan to copy your existing installation to the new drive you need
the following two lines in your /etc/modprobe.conf file:
alias scsi_hostadapter libata
options libata ignore_hpa=1
If you plan on installing a fresh system on the new drive take a look in the
2 Installation section above. During the installation the proper entries are written
to /etc/modprobe.conf.
4 IEEE 1394 Firewire
With FC5 and later there should not be any problems with the IEEE 1394
Firewire support. For me it works just as smooth as the USB support. If you are
running kernel version 2.6.14 or later you may skip this section, unless you have
specific interest in tweaking you Firewire settings.
A new alternative driver stack for Firewire support (a.k.a Juju) was introduced as
experimental in kernel version 2.6.22. In Fedoras kernel configuration
2.6.23.9-85.fc8 the new IEEE1394 driver stack replaces the old drivers. The rest
of this section deals with the old driver stack, i.e before Fedora kernel
2.6.23.9-85.fc8. For the most recent information please refer to
However, on systems with kernel version 2.6.13 or earlier some might experience
problems with the Firewire support due to different default values used in the
kernel module. First a short description of the potential problems.

4.1 Potential problems
There are no problems regarding loading modules or mounting an external IEEE
1394 drive, and if you are patient you managed to browse the content as well.
The problems starts when you try to transfer larger amounts of data. The process
stalls and chokes up the system log with messages like:
kernel: ieee1394: sbp2: aborting sbp2 command
kernel: scsi1 : destination target 0, lun 0
kernel:
command: Write (10): 2a 00 02 e1 bc 58 00 00 10 00
kernel: ieee1394: sbp2: aborting sbp2 command

kernel: scsi1 : destination target 0, lun 0
kernel:
command: Write (10): 2a 00 02 e1 bd b0 00 00 20 00
Seems to me like a hole bunch of timeouts with corresponding bus resets. These
suspicions got even stronger after timing a read data transfer:
# time cp -rp /media/ieee1394disk/430MB_folder ~
real
user
sys
20m29.516s
0m0.052s
0m6.476s
Copying 430 MB takes 20 minutes 29 seconds (comparable to USB 1.0
performance). However, the “actual” time is less than 7 seconds. 20 minutes and
22 seconds are spent waiting. Waiting for what? I do not know, but obviously
some bits and pieces fail during the transfer. Furthermore, I do not feel
comfortable with the data integrity when I see these kind of results.
After some digging in the kernel documentation and a quick look in the sbp2.c
source file it turned out that this problem probably is related to a “buggy IEEE
1394 chip” in the external device. The proposed solution is to load the sbp2
module with the argument serialize_io=1. It turned out really well, so here are
some tips regarding the IEEE 1394 configuration.

4.2 Configuring Firewire
If you experience the problems mentioned above, and you are running kernel
version 2.6.13 or earlier, put the following line in your /etc/modprobe.config:
options sbp2 serialize_io=1 max_speed=2
The serialize_io=1 option tells the scsi drivers to only send one scsi command
at a time. Unfortunately, this setting has a small impact on performance, but it is
the fix that makes things work.
In kernel version 2.6.14 the default value for serialize_io was changed from 0
to 1. Thus, if you are running kernel version 2.6.14 or later you should not need
do do anything, unless you want to optimize performance (see comments below)
or fiddle with the other settings.
The max_speed option might be useful in rare occasions if you want to limit the
maximum transfer rate to support “even more buggy” external hardware. Valid
values for the max_speed option are:
0
1
2
3
100 mb
200 mb
400 mb (default)
800 mb
When timing the very same read transfer as above I now get the following result:
# time cp -rp /media/ieee1394disk/430MB_folder ~
real
user
sys
0m24.871s
0m0.076s
0m6.400s
That is what I call improvement! Going from over 20 minutes down to roughly 25
seconds.
4.3 Comments
After some further exercises with other external hard drives it turned out that the
problem described in the previous section indeed seems to be related to the IEEE
1394 chip in the external drives. With some hardware it is quite possible to use
the faster serialize_io=0 option. The performance benefit is in the range
20-25%, so consider your options. If you only use IEEE 1394 for your own
hardware and it works well with the faster setting, go for it. Otherwise,
compatibility with other hardware might be more valuable. Personally, I think it
was a wise decision to change the default setting in the sbp2 module. After all
those “buggy IEEE 1394 chips” seem to be quite common, and prior to start

optimizing performance you just want things to work.
5 USB
USB support works as expected. I have noticed no problems what-so-ever with
the USB ports. Especially with the desktop enhancements introduced with FC5 it
works like a charm. Absolutely no configuration needed.
6 5-in-1 Card reader
The 5-in-1 card reader utilizes the USB interface and is operational right after
installation. Analogous to the USB ports there is no hassle at all.
7 PC-card
I have only used the PC-card slot for a Compact Flash memory adapter and it just
works. True plug-and-play.
8 Special keys & buttons
The special keys & buttons are some what confusing. Some of the special buttons
do not need any additional configuration to work. Others need a key code
mapping, while some even lack a scan code. The chain of scan codes and key
codes translations starts in the core Linux kernel and ends in your X
configuration. Some examples of confusion:
The Mail button gets a pre-configured key code of 155 by Linux, but with X
loaded the key code is 236. The buttons WWW, Fn-F4, Fn-F5, Fn-F8, Fn-up and
Fn-down show similar behavior.
The buttons P1, P2, Fn-F1, Fn-F2, Fn-F3 do not have pre-configured key codes,
while their respective scan codes are e074, e073, e025, e026 and e027. However,
in single user mode they all lack scan-codes. I do not know why.
However, do not despair. It is possible to get all of the special keys & buttons
working. Here is a short summary of my current status on this issue.

8.1 Configuration procedure
It is a tedious procedure to find out the proper scan-codes, Linux key-codes and
X key-codes. Yes, on top of the scan-codes there are both Linux and X key-codes
to keep track of. I probably have it all confused, but here is how I did it:
8.1.1 X key-codes
1. Start by finding out what key-codes X already knows of. Here xev is a
valuable friend. The buttons that had key codes configured by default for

These are the buttons that are the simplest to get working. Save these X key-
codes for future use. First we need to get the other keys to show up under X as
well. In order for them to do so they need properly configured Linux key-codes
that they lack for the moment.
8.1.2 Scan-codes
This step is different and considerable easier under F8 than FC4 or FC5. There is
no need to shutdown X now as before.
2. Just press the desired key, ex. P1. Then take look at the dmesg output:
# dmesg | tail
atkbd.c: Unknown key pressed (translated set 2, code 0xf4 on
isa0060/serio0).
atkbd.c: Use 'setkeycodes e074 <keycode>' to make it known.
atkbd.c: Unknown key released (translated set 2, code 0xf4 on
isa0060/serio0).
atkbd.c: Use 'setkeycodes e074 <keycode>' to make it known.
I got the following result:

Linux scan-code – key-code mapping.

4. First we need to set a Linux key-code for the keys that lack one. Add the
following lines to /etc/rc.d/rc.local to set the key-codes after all
services are started.

5. In order to avoid a restart to load these setting, issues the very same
commands.
# setkeycodes e074 151 e073 152
# setkeycodes e025 131 e026 132 e027 133
8.1.4 X key-codes revisited
6. Repeat step 1 and use xev to figure out what X key-codes these buttons
got. I got the following:

146
Fn-F1
Fn-F2
Fn-F3

7. Ok, now we have X key-codes for all special keys & buttons and need to
map them to proper key-symbols. In order to do that put the following in
the file /etc/X11/Xmodmap:
! Acer Ferrari 3400Lmi special keys & buttons

keycode 214 = XF86Display
keycode 160 = XF86AudioMute
keycode 176 = XF86AudioRaiseVolume
keycode 174 = XF86AudioLowerVolume
8. The setting above are loaded the next time X is started, but to load them
without a restart of X do:
# xmodmap -verbose /etc/X11/Xmodmap
...
!
! executing work queue
!
keycode 0xec = XF86Mail
keycode 0xb2 = XF86WWW
keycode 0xc9 = XF86Launch1
keycode 0x92 = XF86Launch2
keycode 0x87 = XF86Launch3
keycode 0x8c = XF86Launch4
keycode 0xf8 = XF86Launch5
keycode 0xd6 = XF86Display
keycode 0xa0 = XF86AudioMute
keycode 0xb0 = XF86AudioRaiseVolume
keycode 0xae = XF86AudioLowerVolume
8.1.5 Configure actions
9. Finally it is time to configure the button actions. Actions for all but the
audio control keys are easily configured in the KDE Control Center ->
Regional & Accessibility -> Keyboard Shortcuts under the tab Command
Shortcuts.
10. However, you probably also want to configure the audio control buttons.

9 CPU & ACPI support
A pleasant news is the advancements in ACPI support. Now all the desirable
features are working right out of the box, without any configuration.

9.1 Suspend
I am glad to see that both Suspend to Disk and Suspend to RAM works like a
charm. Previous there has been a lot of struggle, if at all possible, to get a stable
and reliable ACPI support. OK, I know that suspend has been around for a while
by now, but hand on the heart - has it been user friendly and reliable? I have not
had that experience. So a reliable ACPI support right out of the box feels really
luxurious.
Even the special sleep key, Fn-F4, is configured during the installation and works
as expected (Suspend to RAM). The power button works of course as well, as it
always has done.
9.2 CPU frequency scaling
The CPU frequency scaling has been working for quite some time now. So it is no
big surprise that it works out of the box in F8 on this puppy. However, it is
always nice to see things evolve and improve. The improvements of the suspend
functionality mentioned above together with solid CPU frequency management
really shows off in power management.
KPowersave now feels really mature and has three pre-configured CPU policies:
Performance, Dynamic and Powersave. Dynamic is the default and there is no
real reason to change it.
10 Graphics
The advancement of Xorg and its related drivers and modules has been enormous
the last two years. Fedora 8 includes Xorg 7.2 which is a welcome improvement
in X-server configuration. Furthermore, there is absolutely no need to use the ATI
proprietary driver any more. This is a true liberation, for sure I will not miss all
the violations the proprietary ATI driver did to my Xorg configuration.
The graphical hardware is properly identified and setup during the installation,
so you will enjoy X11 right from the start.
Another nice thing is that the dim display button, Fn-F6, works without any
configurations.
10.1 Basics
The Ferrari 3400 is equipped with a ATI Mobility Radeon 9700 chip. This chip
has 128MB of memory and provides two external outputs, VGA-0 and S-video.
The built-in display is called LVDS. These names refer to the definitions used by
the radeon X driver.
The graphical chip has 2 CRTCs, eg pipeline for rendering graphics. This means
that only two outputs may be active simultaneously, either LVDS + VGA-0, LVDS
15

+ S-video or VGA-0 + S-video. This is a common limitation for most graphics
hardware.
Note: The output names differ depending on the driver used. The names used in
this document relate to the radeon driver. If you use some other driver use
xrandr -q to find out the proper names (provided that it supports RandR).
10.1.1 The radeon driver
Support for the ATI Mobility Radeon 9700 chip in the Ferrari is provided by the
radeon driver. This driver supports all the features we want: the RandR
extension (v 1.2), 3D acceleration (DRI) and TV-out.
There is also the ati driver, not to be confused with the proprietary fglrx
driver. However, the ati driver is only a wrapper that auto-detects ATI cards and
load the appropriate driver. In our case that will result in the radeon driver being
loaded.
The main improvement in Xorg 7.2 is the arrival of version 1.2 of the X RandR
(Resize and Rotate) extension. It provides automatic discovery of modes together
with the ability to configure outputs dynamically. As of today only a few drivers
support RandR 1.2. Fortunately, the radeon driver is one of them.
10.1.2 Simple configuration
If you are familiar with X configuration and take a look at the default
/etc/X11/xorg.conf file, generated during the installation you will notice a
significant change. Many of the traditional settings, sync and refresh rates,
modes and modelines, are gone. All these settings are now auto-detected by
RandR 1.2 and should only be present if you want to override the detected values.
In some rare situations this might be needed, e.g. when an external monitor
reports incorrect values.
In order to get full dual-head support you only need to add one line to the default
X configuration. If you want to optimize 3D acceleration you need another line.
That is a total of two lines for a full fledge X configuration supporting all features.
Quite an improvement. Thank you all nice X guys!
The X server log file /var/log/Xorg.0.log will be your valuable companion
when it comes to troubleshooting or just checking what configuration that is
auto-detected.
10.2 Dual-Head
The X Resize and Rotate (RandR) extension introduces a significant shift in dual-
head configuration with its version 1.2. All your setting may now be altered on

F8-x86_64 on the Acer Ferrari 3400LMi
the fly by the command line tool xrandr, and there is no need to restart the X
server.
10.2.1 Virtual screen size
RandR works its magic by means of a virtual screen that is larger than the a
single monitor.
The size of the virtual screen is reported as the maximum value by the command:
# xrandr -q
Screen 0: minimum 320 x 200, current 1400 x 1050, maximum 1400 x 1200
...
In this case the size is 1400x1200, which is the default virtual screen size for this
setup. The default screen size is too small for serious dual-head configurations.
This value needs to be increased by setting the Virtual option in the Display sub-
section in /etc/X11/xorg.conf:
SubSection "Display"
Viewport
Depth
0 0
24
Virtual
3000 2000
EndSubSection
This is the most (only) important setting needed in xorg.conf. However, in order
to enjoy hardware support for 3D acceleration the virtual screen may not be
larger than 3000x2000. This limitation differs for the various driver, but for the
radeon driver the limitation is 3000x2000. This is sufficient for having an
external monitor running at 1600x1200 side-by-side with your internal display as
1400x1050.
After modifying xorg.conf you need to restart your X server, ie. logout and logon
again. Now, check your settings once again:

S-video disconnected (normal left inverted right x axis y axis)
In the xrandr -q output above we see that the new virtual screen size is
recognized in the maximum value. Furthermore, we see our three supported
outputs, VGA-0 (external display), LVDS (internal display), S-video (TV-out). For
the report above an external monitor is connected but not activated. Still
xrandr -q reports its supported modes. Neat!
10.2.2 The xrandr tool
It is highly recommended that you read through the man page for xrandr and
play with it a bit to get to know it. A good place to start is at the debian wiki
http://wiki.debian.org/XStrikeForce/HowToRandR12. It is a great tool that you
most likely will find useful. Connect an external monitor and try the following
commands.
Get a full report of the current status by:
# xrandr --verbose
Activate the external monitor with its default mode and mirror the internal
display:
# xrandr --output VGA-0 --auto
Put the external monitor to the left of the internal panel with:
# xrandr --output VGA-0 --left-of LVDS
Change resolution and refresh rate of the external monitor:
# xrandr --output VGA-0 --mode 1024x768 --rate 60
Turn off the external monitor:
# xrandr --output VGA-0 --off
Set the TV-output in PAL mode instead of the default NTSC:
# xranrd --output S-video --set tv_standard pal
10.2.3 Fn-F5 button
Once the virtual screen is configured and we feel confident in xrandr, it is time to
focus on the Fn-F5 special button. By default it does nothing, but now we have
the tools to configure it the way we want it to work.
First the Fn-F5 button needs to be recognized, so please refer to the section
18
Download from Www.Somanuals.com. All Manuals Search And Download.
F8-x86_64 on the Acer Ferrari 3400LMi
we design a script to run once Fn-F5 is pressed.
The Fn-F5 button should provide a simple, basic and robust functionality that
works for any external monitor. I prefer to toggle through the available connected
external outputs, while keeping the internal monitor alive. Furthermore, each
connected external output is present in two operating modes. First the external
output mirrors the internal display, then it extends the desktop by operating
side-by-side with the internal display. When both VGA-0 and S-video are
connected the following operation modes are toggled each time Fn-F5 is pressed.
● LVDS (single head)
● LVDS + VGA-0 (mirror)
● LVDS + VGA-0 (side-by-side)
● LVDS + S-video (mirror)
● LVDS + S-video (side-by-side)
If a certain external device is not connected those modes are skipped.
Consequently, the sequence above will only appear when both VGA-0 and S-video
are connected. With only VGA-0 connected the sequence will only include the first
three modes from above.
Notice that the internal monitor may be dimmed at any time by pressing the
Fn-F6 button. Thus, turning off the internal monitor is not included in the script.
The script also includes some other common operation to manipulate the
graphical outputs. To see all supported operations, try:
dual-head.sh help
Binding this script to the Fn-F5 button is then configured in the
KDE Control Center -> Regional & Accessibility -> Input Actions.
If you run a more permanent dual-head setup you may want to configure the
preferred default settings in xorg.conf. This is done by the Monitor sections and
the lines
Option ”Monitor-<output>” “...”
in the Device section of the xorg.conf file.
10.3 3D acceleration
3D hardware acceleration is provided by the dri module. This module is loaded
by default by the radeon driver, so no additional configuration is needed in
xorg.conf to get hardware support for 3D. However, any possible optimizations
that might improve performance are desirable.

F8-x86_64 on the Acer Ferrari 3400LMi
10.3.1 Simple benchmark
In order to compare different settings we need some kind of benchmark tool. A
simple tool that comes with the glx-utils package found in most distributions
is glxgears. It may be rough, rudimentary and lacking a lot of hype features, but
it is present and sufficient for our needs.
An interesting exercise is to explicitly disable hardware acceleration and
comparing the result with the default xorg.conf. Without hardware acceleration
glxgears clocks in around a modest frame rate of 150 FPS, compared with
approximately 2050 FPS for the default configuration. This is quite a difference,
and it verifies that the radeon driver really does its job.
10.3.2 Optimization
The default values for most settings work well and there is no needed to modify
xorg.conf. Furthermore, most of the other settings are correctly auto-detected,
such as AGP 8x and memory. All this is reported by the X server in its log file
/var/log/Xorg.0.log during startup.
The options of most interest for performance are AccelMethod (default XAA),
AGPMode (auto-detected), ColorTiling (default on) and EnablePageFlip (default
off). The first three are correct by default, but due to instability in rare cases
EnablePageFlip is disabled by default.
Turning on the option EnablePageFlip in xorg.conf reveals no flaws. I have not
noticed any glitches with this option on my setup so I feel confident in
recommending it. Then the obvious question How good is it? It is good!
glxgears gives us an indication. By enabling EnablePageFlip performance is
increased from 2050 FPS to about 3270 FPS. A significant boost for tweaking one
single option.
You only need to add one line to the Device section in the default xorg.conf to
boost 3D performance:
Section "Device"
Identifier "Videocard0"
Driver
"radeon"
Option
"EnablePageFlip"
"1"
EndSection
10.3.3 Other observations
During the optimization procedures a few interesting observations were made.
Primarily the CPU speed does not seem to matter. Most tests were run with the
CPU frequency first set to 800MHz, then repeated at 2000MHz. No significant
difference related to the CPU speed was noticed.
Furthermore, the size of the configured virtual screen does not affect
20

F8-x86_64 on the Acer Ferrari 3400LMi
performance. The tests has been run with the default size (1400x1200) and with
3000x2000, but no difference has been noticed. However, increasing the virtual
screen to more than 3000x2000 will disable hardware acceleration and of course
cripple performance completely.
These observations verifies that hardware 3D acceleration is really working and
that the radeon driver is taking care of business the way we want it to.
10.4 TV-out
TV output is available through the S-video connector on the rear of the Ferrari.
Furthermore, no special settings are needed in order to use it. It is immediate
available and may be controlled by xrandr. However, the tips below might help to
get you started.
10.4.1 Load detection
The external outputs have a property called load_detection, that controls
whether RandR should try to auto-detect the output or not. Usually it is a good
thing to be able to auto-detect the different output features. However, there are
situations when you do not want auto-detection.
Remember that we have three outputs, but only two rendering pipelines (CRTCs).
What would then happen if we try to auto-detect and configure all available
outputs, xrandr --auto, with both VGA-0 and S-video connected? We actually
do not know. The internal display may only use the first pipeline, CRTC 0, but
that might be allocated by either VGA-0 or S-video. Furthermore, we will have a
race condition between the two remaining outputs for the second pipeline,
CRTC 1. In order to avoid potential conflicts like that, auto-detection is disabled
by default for S-video.
Thus, we first have to enable load_detection in order to use the TV-output.
That is done by:
# xrandr --output --set load_detect 1
10.4.2 NTSC or PAL
The graphics chip defaults to NTSC, so those of us how want PAL need to
explicitly specify this. To change the TV mode to PAL use:
# xrandr --output S-video --set tv_standard pal
10.4.3 Initialization
external outputs may be auto-detected. Thus, if you want the script to consider
TV-out as a possible external output you need to enable auto-detection for TV-
out.
Consequently, we need to initialize some settings before TV-out is automatically

F8-x86_64 on the Acer Ferrari 3400LMi
handled by the script. The script includes an initialization option that may be
used for this. Put the following line in the file /etc/rc.local:
/usr/local/bin/dual-head.sh init
11 Touch-pad
The Synaptics touch-pad is properly configured during the installation, and
works well. I use it in conjunction with a USB mouse and both works well in
parallel. I have seen some reports on problems with the touch-pad 4-way multi-
button, but it works without any hassle for me. Likewise does the mouse wheel.
The InputDevice section in xorg.conf configured during the installation works
well and needs no modification:
Section "InputDevice"
Identifier "Synaptics"
Driver
Option
Option
"synaptics"
"Device" "/dev/input/mice"
"Protocol" "auto-dev"
"Emulate3Buttons" "yes"
Option
EndSection
The special key to toggle the touch-pad (Fn-F7) also works without any special
configurations.
12 Wireless NIC
When it comes to the Broadcom BCM4306 802.11b/g WLAN chip on the Ferrari
you have two choices. The traditional NdisWrapper or the kernel module b43.
When I first got this laptop there was no other option than NdisWrapper, but
lately the kernel module b43 has evolved and matured.
As its name implies NdisWrapper is a wrapper for NDIS drivers, meaning that you
use a corresponding Windows driver instead of a Linux driver. For some WLAN
chips this is still the only option, but lately many chips enjoy almost native Linux
support by means of kernel modules. I say “almost” because many chips need to
be fed with proprietary firmware in order to operate. Anyway, this is a step in the
right direction, and the final goal must be to free the firmware as well.
With FC4 NdisWrapper was the obvious choice, but during FC5 its configuration
was (deliberately?) broken by the updates. Most FC5 updates re-installed the now
deprecated bcm43xx kernel module, even though it was previously disabled and
blacklisted. Thus, for most FC5 updates I had to disable the kernel module once
again and re-install NdisWrapper. In my opinion, the bcm43xx kernel module was
not mature enough to compete with NdisWrapper at that time. So this was an
endless struggle to keep my WLAN support alive.

F8-x86_64 on the Acer Ferrari 3400LMi
However, with F8 the b43 kernel module is mature, stable and ready for
production. How to get the b43 kernel module to work is described below. To use
the NdisWrapper please refer to the FC4 version of this document, found at
12.1 Installing WLAN
First we need to check and install some software so we have the tools we need.
12.1.1 WLAN tools
1. First we needed to make sure that the b43 kernel module is compiled and
properly loaded during system startup. For standard F8 kernels this is the
case, but if you compile your own brew you need to build it as a module:
# dmesg | grep b43
b43-phy0: Broadcom 4306 WLAN found
b43-phy0 debug: Found PHY: Analog 2, Type 2, Revision 2

2. Next we need to make sure that the wireless-tools package is installed on
our system:
# rpm -q wireless-tools
wireless-tools-29-0.2.pre22.fc8
If not, we need to install it:
# yum install wireless-tools
or
# rpm -Uvh wireless-tools-29-0.2.pre22.fc8.x86_64.rpm
3. Finally we will need the b43-fwcutter package. Make sure that it is installed:
# rpm -q b43-fwcutter
b43-fwcutter-008-1.fc8
or install it:
# yum install b43-fwcutter
12.1.2 WLAN firmware
4. Now we need to download the Broadcom driver, so we may extract the
23

F8-x86_64 on the Acer Ferrari 3400LMi
firmware from it later. Download it at:
or I keep a local copy, just in case:
5. Uncompress the driver:
# tar jxf broadcom-wl-4.80.53.0.tar.bz2
6. Extract and install the firmware from the Broadcom driver as root:
# cd broadcom-wl-4.80.53.0/kmod/
# b43-fwcutter -w /lib/firmware wl_apsta.o
12.2 Get started with WLAN
Now that we have all the pieces we need installed, it is time to check the
functionality and get things working.
12.2.1 The manual way
First we do it manually, to make sure we get the results and feedback that we
expect. This is to verify the functionality and simplify troubleshooting, if needed.
7. The WLAN interface should show up:

Now you are ready to start using your new interface. Most likely your first step
will be to request IP setting from an DHCP server (dhclient -1 wlan0). The next
step is probably to permanent your preferences in the file
/etc/sysconfig/network-scripts/ifcfg-wlan0.

12.2.2 The GUI way
Once you have verified that you have the wireless network chip operational, as
described in the previous sections, it is time to have a look at a GUI that will help
you with all these steps and some other valuable tasks. The NetworkManager is a
service with a corresponding applet that will dock into your panel. It is included
in most distributions nowadays and is started by:
# service NetworkManager start
# service NetworkManagerDispatcher start
Try it out and play with it, if you like it and want it to start at system startup
type:
# chkconfig --add NetworkManager
# chkconfig --add NetworkManagerDispatcher
# chkconfig --level 5 NetworkManager on
# chkconfig --level 5 NetworkManagerDispatcher on
13 Bluetooth
No special actions were needed for me to get Bluetooth up and running. It was
truly amazing how easy it was. However, in order to be complete the details are
summarized below.
13.1 Verify installation
Make sure that you have the bluez-utils package installed:
# rpm -q bluez-utils
bluez-utils-2.25-4
Also make sure that it is configured to start at boot time:
# chkconfig --list bluetooth
bluetooth
0:off 1:off 2:on
3:on
4:on
5:on
6:off
If not, you need to add it to the runlevel system:
# chkconfig --add bluetooth
Now watch your system log while you push the bluetooth button on the front of
your laptop to activate your bluetooth circuities:
# tail -f /var/log/messages

13.2 Using a phone modem
To help get you started I have summarized the basic steps to hook up your
bluetooth capable phone as a modem. I am using a Sony Ericsson P900 myself,
but the steps are general so it should work for most bluetooth phones.
The steps below are exactly the same whether you intend to connect to a remote
modem or connect over GPRS. When connecting over GPRS the phone also needs
to be connected and recognized as a modem. It is the actual dialing later on in
the process that differs.
With FC4 and FC5 I experienced some issues with the PIN-helper, i.e. the dialog
window that prompts for a PIN code. However, no such issues has been observed
with Fedora 8.

13.2.1 Prepare the phone
First you need to configure your phone so it is available to your laptop. These
steps may vary in detail depending on vendor and model, so the user manual for
your phone may be handy.
Start by activating bluetooth on your phone and scan for other devices. You
should now be able to see your computer.
Add your computer as a known bluetooth device to your phone. The phone will
ask you for the pin code to connect to your computer. By default it is BlueZ, but
you may modify it in /etc/bluetooth/hcid.conf. Use the same pin code when
the computer prompts you whether to allow the incoming connection.
For convenience you should now configure your phone to allow this device (your
computer) to connect without prompting for a pin code.
13.2.2 Prepare the laptop
Now we are ready to configure the laptop. Start by scanning for bluetooth devices
in your surrounding:
# hcitool scan
Scanning ...
00:0A:D9:E9:D8:4F
S-Gs P900
The first field is the bluetooth address of your phone. The second field contains
its given name. You should also be able to ping it by its address:
# l2ping 00:0A:D9:E9:D8:4F
Ping: 00:0A:D9:E9:D8:4F from 00:0E:9B:87:3B:90 (data size 44) ...
0 bytes from 00:0A:D9:E9:D8:4F id 0 time 60.87ms
0 bytes from 00:0A:D9:E9:D8:4F id 1 time 27.77ms
0 bytes from 00:0A:D9:E9:D8:4F id 2 time 36.54ms
3 sent, 3 received, 0% loss
Note that you should use your own phones address instead. (My phone will
probably be out of range :-)
Now it is time to find out what services your phone provides:

Version: 0x0100
To use the phone as a modem the service of interest is the Dial-up Networking, so
note its channel number.
The next step will be to create a virtual serial device and connect it to your phone:
# rfcomm connect 1 00:0A:D9:E9:D8:4F 4
Connected /dev/rfcomm1 to 00:0A:D9:E9:D8:4F on channel 4
Press CTRL-C for hangup
A short explanation of the command above:
rfcomm connect 1 00:0A:D9:E9:D8:4F 4
|
|
|
/dev/rfcomm1 _|
|
|_ Channel for the Dial-up
Networking service
Your phones
bluetooth address
That is about it. Now your phone is analogue to an external modem connected
to your virtual serial device, /dev/rfcomm1. Configure ppp to make use of it
and you are done.
13.2.3 Static configuration
Ok, now what? Do I need to repeat all the steps above each time I want to use my
phone as a modem? No, for convenience you may configure your system for all
this to take place automatically. However, the method you should use depends a
bit on your phone.
The preferred method is to edit the rfcomm.conf file so a /dev/rfcommX port
automatically binds to the DUN service on your phone when the bluetooth service
starts. This means that the virtual serial device will be created and properly
configured, but not connected. The actual connection will happen automagically
when the virtual serial device is accessed.
Edit the file /etc/bluetooth/rfcomm.conf to contain a section similar to this:
rfcomm1 {
# Automatically bind the device at startup
bind yes;

device 00:0A:D9:E9:D8:4F;
# RFCOMM channel for the Dial Up Networking service
channel 4;
# Description of the connection
comment "Modem on my phone";
}
13.2.4 Dynamic routine
If the method above works, you are all set and done. I started out that way and
everything worked great for a while. Then all of a sudden I was unable to connect.
It turned out that the DUN channel on my phone had changed!?! Instead of 4 as
in the example above it showed up as channel 2, and later on as channel 3...
The statical configuration done by editing the rfcomm.conf file cannot handle
this confusion. Instead I needed to dynamically decide which channel my phone
used for the DUN service today and bind to it.
This is done in a simple shell script, that is called just before I intend to connect.
Personally, I use Kppp and find it great for both modem-to-modem dial-ups and
GPRS connections. So, I have configured KDE to call my script just before Kppp
is opened.
First I was a bit suspicious about this method to work all the time, but I have not
had any trouble this far and I have been using it for years now. You may find a
http://ferrari.databa.se/3400/f8/dun-bind.sh. Obviously, you will need to
change the name of the bluetooth device, BTNAME, and maybe the port to connect
it to, RFPORT. Once that is done you may test run it:
# chmod +x dun-bind.sh
# ./dun-bind.sh
Checking for local Bluetooth device...
Checking that /dev/rfcomm1 is free...
Searching for remote Bluetooth device S-Gs P900...
Searching for Dial Up Networking service...

13.2.5 GPRS
As mentioned earlier the only difference between dialing modem-to-modem or
using the phone as a GPRS gateway to internet is just a matter of configuration.
Basic knowledge about modem commands and dialing is assumed, so modem-to-
modem dialing is not described here. However, some short hints on GPRS
connections are given below.
A GPRS connection is established by means of modem configuration rather than
actual dialing. Two AT command strings are vital for GPRS connections. First a
configuration string is used to specify things like protocol and network provider.
This string is passed during modem initialization and in my case it is:
AT+CGDCONT=1,”IP”,”services.vodafone.net”,””,0,0
After initialization the actual dialing is substituted by sending a connection
request to the network provider. The request contains the type of connection you
want to use, e.g PPP. It should look similar to:
AT+CGDATA=”PPP”,1
When used in a connection tool like Kppp the sequence of AT commands may
look similar to the one in the snapshot below.
32

F8-x86_64 on the Acer Ferrari 3400LMi
Notice the two AT strings discussed above. The other commands are mainly
cosmetic and may differ depending on your tool and its configurations.
13.3 Sending files
To send files to your OBEX (Object Exchange) capable phone you need the
packages openobex and openobex-apps.
# obex_push 3 00:0A:D9:E9:D8:4F test.jpg
|
|
|
|
|_ Bluetooth address to send to
|_Channel for the OBEX Object Push service
A more convenient way to do this is to use the KDE extension KBluetooth
described in its own section below.
13.4 Mouse & keyboard
Once you have got bluetooth working it is a breeze to use a bluetooth mouse
and/or keyboard, a.k.a Human Input Device. First you need to scan for your
device. Make sure that bluetooth is activated on both the laptop and the
mouse/keyboard. Then press the setup button on the mouse/keyboard to make
it announce itself and type:
# hidd --search
Searching ...
Connecting to device 00:0A:94:C1:B6:5D
In the next section you will find a more user friendly and persistent way of
connecting your bluetooth mouse/keayboard.
13.5 KBluetooth
If you are running KDE, there is a Bluetooth extension called KBluetooth
available. There is a similar package available for Gnome users, but KBluetooth is
discussed here. Before starting to explore it you should make sure that all the
details work. For this reason it is recommended that you start out with only the
basic bluez-utils package as described in the sections above. Once your bluetooth
works as expected, go ahead and install KBluetooth.
13.5.1 Installation
Once the details are in place and you know how things work, you may start to
play around with KBluetooth. First verify that it is installed by:
# rpm -q kdebluetooth
kdebluetooth-1.0-0.37.beta8.fc8
33
Download from Www.Somanuals.com. All Manuals Search And Download.
F8-x86_64 on the Acer Ferrari 3400LMi
or install it with:
# yum install kdebluetooth
After installing kdebluetooth you need to restart KDE, by logging out and back on
again. Once KDE is restarted KBluetooth will show up as a bluetooth icon in the
panel. It offers several useful features.
13.5.2 Mouse & keyboard
Connecting a bluetooth mouse or keyboard with KBluetooth is really simple.
Activate the mouse and move it around and it will be detected automatically. The
first time it is detected an authentication dialog is raised.
If you want to use the same device in the future without a new acknowledge press
Always Accept, otherwise just press Accept. Could it be easier?
13.5.3 Scan for devices
KBlueMon is a basic tool to scan for bluetooth devices nearby. It reports both
device address and name, signal strength as well as what services the device
provides.

13.5.4 Lock screen
KBlueLock may be used to lock the screen whenever a bluetooth device becomes
unreachable. Once the device appears again the screen is unlocked. This is a very
convenient security measure to prevent others from fiddling with your Precious
when you leave it unattended.

13.5.5 Transfer files
The Bluetooth OBEX Object Push client may be used to transfer files from the
computer to your phone or other bluetooth device.
14 Infrared
IrDA support is provided by means of the package irda-utils, so first make
sure that this package is installed on your system.
My first attempt started with changing the DEVICE in /etc/sysconfig/irda to
/dev/ttyS1 and fire up the IrDA service (/etc/init.d/irda start). Voilà!
Watching the log messages verified that all modules were loaded and I had got a
new device, irda0, to play with. The device showed up with ifconfig as well. It
was just too easy! And yes, although all looked perfect it did not work. Trying the
irdadump reviled just a big silence.
14.1 Configuring IrDA
To make a long story short, the IR-chip in the Ferrari supports FIR (as well as
SIR) and FIR is the default, while IrDA by default uses SIR. FIR is what you want
36
Download from Www.Somanuals.com. All Manuals Search And Download.
F8-x86_64 on the Acer Ferrari 3400LMi
to go for since it is faster than SIR and there is a stable Linux FIR driver available
for this IR-chip. Below I'll walk you through the steps that got it working for me.
1. Start with grabbing a pen and a piece of paper and restart your Precious.
Yes, this is one of those few occasions when you need to restart you Linux
system. Press F2 during boot-up to enter the BIOS and note the settings for
your IR-port. You do not need to change anything, but you need to know
your exact setting. I will use my own setting through out this example:
Base I/O address: [2F8]
Interrupt:
[IRQ 3]
DMA channel:
[DMA 1]
Once you have noticed your corresponding setting just exit the BIOS
without saving and start your system.
2. Make sure that no other services use IRQ 3. Most likely your setting is also
IRQ 3, so start looking in the /etc/pcmcia/config.opts file. Here you
need to uncomment or insert the line
exclude irq 3
to prevent the pcmcia service from intervening.
3. Now we want a module capable of handling FIR on the Ferrari chip to be
loaded when the IrDA service is started. The module of choice is nsc-ircc,
so add the following two lines in /etc/modprobe.conf:
alias irda0 nsc-ircc
options nsc-ircc dongle_id=0x09 io=0x2f8 irq=3 dma=1
Pay attention to use the settings from your own BIOS for the last three
parameters.
4. We also need to tell the IrDa service to attach directly to the device for our
FIR capable module, so make sure to change the DEVICE setting in
/etc/sysconfig/irda to:
DEVICE=irda0
5. Then we do not want the generic Linux serial driver to interfere. One way of
doing that is to add the following line in /etc/init.d/irda:
setserial /dev/ttyS1 uart none
The line should be place just before
daemon /usr/sbin/irattach ${DEVICE} ${ARGS}
6. While you are at it you might as well disable SIR by commenting out the tty
lines. A short snippet of the final /etc/init.d/irda:
...
#
/sbin/modprobe ircomm-tty 2>/dev/null
37
Download from Www.Somanuals.com. All Manuals Search And Download.
F8-x86_64 on the Acer Ferrari 3400LMi
#
/sbin/modprobe irtty-sir 2>/dev/null
/sbin/modprobe irnet 2>/dev/null
setserial /dev/ttyS1 uart none
daemon /usr/sbin/irattach ${DEVICE} ${ARGS}
...
That is about it, You are done with the configuration.
14.2 Testing IrDA
Now start the IrDA service and watch the system log. Hopefully, you should see
something similar the the following:
# service irda start
Starting IrDA:
[
OK
]
# dmesg | tail
...
ttyS1: LSR safety check engaged!
pnp: Device 00:09 activated.
nsc-ircc, chip->init
nsc-ircc, Found chip at base=0x02e
nsc-ircc, driver loaded (Dag Brattli)
IrDA: Registered device irda0
nsc-ircc, Using dongle: IBM31T1100 or Temic TFDS6000/TFDS6500
This verifies that you have got the proper modules in place. The last step is to
verify that we are able both of transmitting and receiving traffic. So activate IR on
the remote device, e.g. your phone, and place the two IR-ports eye-to-eye. Then
do a dump of the traffic:
# irdadump -i irda0
...xid:cmd 62a9cc0d > ffffffff S=6 s=5 (14)
...xid:cmd 62a9cc0d > ffffffff S=6 s=* redneck hint=0400 [ Computer ]
(23)
...xid:cmd ffffffff < 6f700c8d S=1 s=0 (14)
...xid:rsp 62a9cc0d > 6f700c8d S=1 s=0 redneck hint=0400 [ Computer ]
(23)
...xid:cmd ffffffff < 6f700c8d S=1 s=* P900 hint=9325 [ PnP PDA/Palmtop
Modem Telephony IrCOMM IrOBEX ] (21)
You're all set! The first I did after this was to use irobex_palm3 <SIS-file> to
upload and install GnuBox and some other programs on my phone. To do this
you need to have the openobex and openobex-apps packages installed and your
phone must supports the OBEX protocol. Pretty neat!
15 Modem
The Ferrari 3400 has a Smart Link soft modem installed. After the Ferrari 3400
was produced Smart Link was acquired by Conexant. Conexant has a strange
policy when it comes to providing drivers for it products. Linux drivers are not
38

F8-x86_64 on the Acer Ferrari 3400LMi
provided by Conexant, but by Linuxant. If you want all the features, fax, 56k,
etc., they will charge you for it. Although, a crippled version is free. I do not like
that philosophy at all. First you pay for the product, then they make you pay
again if you want to use it...
Fedora x86_64 has the ALSA kernel module snd_via82xx_modem pre-compiled.
That module is capable of handling the internal soft-modem. Furthermore, this
module is properly loaded at startup. However, the modem is still a Smart Link
soft-modem so we need a corresponding user space daemon that utilize this ALSA
support for our modem.
Notice that the source code distributed by Linuxant is divided in two parts, one
general modem daemon and hardware specific drivers in the form of kernel
modules. Since we already have an ALSA driver for our model we only need the
modem daemon compiled with ALSA support.
great job in providing binary modem daemons, by regular compiles of the
Linuxant code. This daemon may very well be compiled as a 32-bit executable.
Even if we are running on a 64-bit platform.
Note: Unfortunately the modem support is still unstable. Depending on the
versions of the modem daemon and the kernel it might work. Even though, it is
very fragile and might very well break on the next kernel update.
Since I do not use the modem I can live with this situation, but I am not happy
about it. The installation is not too complicated and is outlined below.
15.1 Installing daemon
Here are the basic steps to get the modem daemon up and running:
1. Start by checking that the alsa-utils package is installed:
# rpm -q alsa-utils
alsa-utils-1.0.15-1.fc8
otherwise install it like this:
# yum install alsa-utils
2. Verfiy that the proper ALSA kernel module is loaded and recognizes the
modem:
# aplay -l
...
card 1: modem [VIA 82XX modem], device 0: VIA 82XX modem [VIA 82XX
modem]
Subdevices: 1/1
Subdevice #0: subdevice #0
3. Download the compiled modem daemon, SLMODEMD.gcc4.2.tar.gz, or
39
Download from Www.Somanuals.com. All Manuals Search And Download.
F8-x86_64 on the Acer Ferrari 3400LMi
4. Unpack and install the daemon:
# tar zxf SLMODEMD.gcc4.2.tar.gz
# cd SLMODEMD.gcc4.2
# install -m 755 slmodemd /usr/sbin/slmodemd
5. Verify that the SmartLink driver is able to find and configure an interface
for the modem:
# slmodemd --country=SWEDEN --alsa --nortpriority
symbolic link `/dev/ttySL0' -> `/dev/pts/5' created.
modem `modem:1' created. TTY is `/dev/pts/5'
Use `/dev/ttySL0' as modem device, Ctrl+C for termination.
You may see a complete list of recognized countries by:
# slmodemd --countrylist
6. For convenience I want the modem driver configured as a service that is
started by the Sys V init system. However, the scripts/slmodemd file
shipped with the package needs to be modified a bit in order to accomplish
7. Download and add this script as a service to the Sys V system:
# chmod u+x slmodemd-sysv-init.sh
# ./slmodemd-sysv-init.sh install
8. Now edit your configuration options in /etc/sysconfig/slmodemd:
# A list of all supported country names can be retrieved
# by calling "slmodemd --countrylist" from the shell prompt.
SLMODEMD_COUNTRY="SWEDEN"
# No additional device needed for ALSA mode
SLMODEMD_DEVICE=
# If set to yes the Advanced Linux Sound Architecture
# subsystem is used to make your modem working.
USE_ALSA="yes"
# Other options, see slmodemd --help for details
SLMODEMD_OPTS="--nortpriority"
9. Verify that the new service starts correctly:
# service slmodemd start
Starting SmartLink Modem driver:
[
OK
]
# service slmodemd status
slmodemd (pid 8356) is running...
40
Download from Www.Somanuals.com. All Manuals Search And Download.
F8-x86_64 on the Acer Ferrari 3400LMi
and look in /var/log/messages:
# tail /var/log/messages
...slmodemd: symbolic link `/dev/ttySL0' -> `/dev/pts/6' created.
...slmodemd: modem `modem:1' created. TTY is `/dev/pts/6'
...slmodemd: Use `/dev/ttySL0' as modem device, Ctrl+C for
termination.
Just as the system log says you may now find the modem at /dev/ttySL0.
However, before starting to use the modem you should continue to read about a
potential issue.
15.2 Potential issue
As mentioned in the beginning of this section there might be a potential problem.
It was noticed in my previous attempts to get the modem working and it still
exists. It all depends on your setup. If you get it to play there should be no
problems, until your next update... Otherwise, you will likely notice something
similar to the descriptions below.
15.2.1 Connecting
The problem might occur while establishing a connection. The best way to
observe this is to start slmodemd manually with the debug flag set:
# service slmodemd stop
Shutting down SmartLink Modem driver:
[
OK
]
# slmodemd -d=1 --alsa --country="SWEDEN" --nortpriority
Once the daemon is running in debug mode, dial the preferred number. The
modem goes on-line, dials the number and the other end answers. Before the
connection is established the daemon bails out during the negotiation with the
other part.
It starts to flood the console with the following messages:
...
<212.190899> main: alsa xrun: try to recover...
<212.191065> main: alsa xrun: recovered.
<212.191069> main: dev read = 0
<212.191185> main: alsa xrun: try to recover...
<212.191351> main: alsa xrun: recovered.
<212.191355> main: dev read = 0
...
The slmodemd process is stopped with Ctrl-C or service slmodemd stop from
another console window.
15.2.2 Disconnecting
If you are lucky the modem might be connecting properly and you may use it to
41

F8-x86_64 on the Acer Ferrari 3400LMi
take care of business. Dialing and connecting works fine and the debug output
looks ok. However, when the session is disconnected the debug output goes
south. It will start to flood the console with the exact same messages as seen
above during a connect. In this case we may actually use the modem but need a
small tweak.
My temporary fix for the problem in this case is to restart the slmodemd service
right after disconnecting a session. I configure my dial-up client, Kppp, to execute
/etc/init.d/slmodemd restart upon disconnect. Unarguable this is a really
dirty fix, but works quite well.
15.2.3 System hang
The issue reported above together with the fact that slmodemd runs with real-
time priority by default may be devastating. When the modem daemon goes
insane it will hug your CPU and squeeze it all real hard.
If the daemon has real-time priority you will have a hard to get control over you
system again and a forced shutdown might be the only way out.
Note: You should always run slmodemd with the --nortpriority option set.
Failing to do so might hang your entire system.

Appendix B – dual-head.sh
#!/bin/bash
#
# Available at http://ferrari.databa.se/3400/f8/dual-head.sh
#
# A script to manipulate connected graphical outputs,
# including TV-out. It includes the most common operations
# and may also be configured to run on an XF86Display event.
# Typically Fn-F5 or similar on a laptop.
#
# Prerequisites:
# This script will work with one graphics card only.
# Furthermore it will only work with two CRTCs,
# i.e. two outputs may be simultaneous active.
#
# Comments:
# In order to optimize performance and minimize flicker
# xrandr is at most called twice. Once to read the current
# state and once for setting the new state. Thus, some code
# may look strange at the first glance.
