INTRODUCTION  
The MS-6112 is a high-performance personal computer mainboard based on  
the Pentium® II processor.  
The mainboard uses the highly integrated Intel® 82440LX AGPset which  
optimize the system bandwidth and concurrency with the implementation of  
Quad Port Acceleration (QPA). QPA provides 4-port concurrent arbitration  
of the processor bus, graphics, PCI bus and SDRAM.  
The Intel® 82371AB chipset integrates all system control functions such as  
ACPI (Advanced Configuration and Power Interface). The ACPI provides  
more Energy Saving Features for the OSPM(OS Direct Power Management)  
function. The Intel® 82371AB chipset also improves the IDE transfer rate by  
supporting Ultra DMA/33 IDE that transfers data at the rate of 33MB/s.  
The mainboard also supports the LM78 System Hardware Monitor  
Controller as optional function. The LM78 function includes: CPU /power  
supply/chassis fan revolution detect, CPU/system voltage monitor, system  
temperature monitor, and chassis intrusion detect(optional).

timing depending on the “DRAM Speed” selection. Choose disable to  
customize setup.  
EDO DRAM Speed (ns)  
This option specifies the RAS access time (in nanoseconds) for the  
DRAM used in the computer. The settings are 50,60 or 70. The Optimal  
default setting is 60 and the Fail-Safe default setting is 70.

assertion of RAS#(SRAS#) in 66MHz.  
3-11  
AMI® BIOS USER’S GUIDE  
CHAPTER 3  
SDRAM CAS Latency  
This option determines the CAS latency time parameter of SDRAM.  
The settings are 2 clks or 3 clks.  
SDRAM RAS Precharge Time  
This option defines the RAS# precharge requirements for the  
SDRAM memory type in 66MHz clocks.  
DRAM Integrity Mode  
During ECC, this will enable the DRAM ECC mechanism that allows  
detection of single-bit and multiple-bit errors and recovery of single-bit  
errors. During EC, the ECC logic will calculate 8-bit pattern written along  
with 64-bit data into the main memory. During Read operation, 8-bit ECC  
code is read along with 64-bit data and error checking is performed. No  
correction of data will take place in this operation mode. During Disabled,  
this will disable the ECC mechanism.  
Note: If you choose ECC or EC modes, you must use a DIMM with ECC  
byte.  
VGA Frame Buffer USWC  
The Pentium® II processor supports the Uncacheable Speculatable  
Write-Combining (USWC) memory type. The processor provides a write-  
combining with buffering strategy for write operation. This is useful for  
frame buffering. Writing to USWC memory can be buffered and combined in  
the processors write-combining buffer (WCB). The WCBs are viewed as a  
special purpose outgoing write buffers, rather than a cache. The WCBs are  
written into memory to allocate a different address, or after executing a  
serializing, locked, or I/O instructions.  
During Enabled, this will enable the processor memory location  
A000 and B000 segment as USWC memory type.

AMI® BIOS USER’S GUIDE  
CHAPTER 3  
PCI Frame Buffer USWC  
The Pentium® II processor supports the Uncacheable Speculatable  
Write-Combining (USWC) memory type. The processor provides a write-  
combining with buffering strategy for write operation. This is useful for  
frame buffering. Writing to USWC memory can be buffered and combined in  
the processors write-combining buffer (WCB). The WCBs are viewed as a  
special purpose outgoing write buffers, rather than a cache. The WCBs are  
written into memory to allocate a different address, or after executing a  
serializing, locked, or I/O instructions.  
During Enabled, this will enable the processor memory location  
C000 and DFFF segment as USWC memory type.  
DRAM Refresh Queue  
Choose Enabled, the system will provide 4-deep refresh queue. All  
refresh request are queued, with the 4th refresh request being the priority  
request. All refresh requests are priority when the refresh queue is Disabled.  
Fixed Memory Hole  
This option allows the end user to specify the location of a memory  
hole. The cycle matching the selected memory hole will be passed to the  
ISA bus. If Enabled, the selected hole is not remapped.  
CPU To PCI IDE Posting  
Set this option to Enabled to enable posted messages from the CPU  
to the PCI bus or IDE controller. The settings are Enabled or Disabled. The  
Optimal and Fail-Safe default settings are Enabled.  
USWC Write I/O Post  
Set this option to Enabled to use USWC(Uncacheable,  
Speculatable, Write-Combined) memory. The settings are Enabled or  
Disabled. The Optimal and Fail-Safe default settings are Disabled.  
3-13  
AMI® BIOS USER’S GUIDE  
CHAPTER 3  
AGP Aperture Size  
This option determines the effective size of the graphics aperture  
used in the particular PAC configuration. The AGP aperture is memory-  
mapped, while graphics data structure can reside in a graphics aperture. The  
aperture range should be programmed as not cacheable in the processor  
cache, accesses with the aperture range are forwarded to the main memory,  
then PAC will translate the original issued address via a translation table  
that is maintained on the main memory. The option allows the selection of  
an aperture size of 4MB, 8MB, 16MB, 32MB, 64MB, 128MB, and 256MB.  
USB Passive Release  
During Enabled, this will allow the PIIX4® to use passive  
release(look at PIIX4® Passive Release) while transferring control  
information or data for USB transaction. During Disabled, PIIX4®  
will perform PCI accesses for USB without using passive release.  
PIIX4® Passive Release  
The PIIX4® ISA bridge support GAT (Guaranteed Access Time)  
mode, which will now violate the spirit of the PCI specification. The systems  
provides a programmable passive release mechanism to meet the required  
master latencies. During Enabled, ISA masters may see long delays in  
accessing PCI memory, including the main DRAM array. The ISA GAT mode  
is also not supported during enable. ISA masters must honor IOCHRDY.  
PIIX4® Delayed Transaction  
During Enabled, the PIIX4® delay transaction mechanism is  
enabled when the PIIX4® is the target of a PCI transaction. A read cycle  
from Host to PCI is immediately retrived due to any pending PCI to DRAM  
cycle. During Disabled, a read cycle from Host to PCI is waited until time-  
out due to any pending PCI to DRAM cycle.

AMI® BIOS USER’S GUIDE  
CHAPTER 3  
Description of the item on screen follows:  
Plug and Play Aware O/S  
Set this option to Yes if the operating system in this computer is  
aware of and follows the Plug and Play specification. Currently, only  
Windows® 95 is PnP-aware. The settings are Yes or No. The Optimal and  
Fail-Safe default settings No.  
PCI Latency Timer (PCI Clocks)  
This option specifies the latency timings (in PCI clocks) for all PCI  
devices on the PCI bus. The settings are 32, 64, 96, 128, 160, 192, 224 or 248.  
The Optimal and Fail-Safe default settings are 64.  
PCI VGA Palette Snoop  
When this option is set to Enabled, multiple VGA devices operating  
on different buses can handle data from the CPU on each set of palette  
registers on every video device. Bit 5 of the command register in the PCI  
device configuration space is the VGA Palette Snoop bit (0 is disabled). For  
example, if there are two VGA devices in the computer (one PCI and ISA)  
and the Bit settings are:  
Disabled - Data read and written by the CPU is only directed to the  
PCI VGA devices palette registers.  
Enabled - Data read and written by the CPU is directed to  
both the PCI VGA device’s palette registers and the  
ISA VGA device palette registers, permitting the  
palette registers of both devices to be identical.  
This option must be set to Enabled if an ISA adapter card requires  
VGA palette snooping. The settings are Enabled or Disabled. The Optimal  
and Fail-Safe default settings are Disabled.  
Allocate IRQ to PCI VGA  
Choose the IRQ to be assigned to the PCI VGA display adapter card.  
The Optimal and Fail-Safe default setting is No.  
3-21  
AMI® BIOS USER’S GUIDE  
CHAPTER 3  
PCI IDE BusMaster  
Set this option to Enabled to specify that the IDE controller on the  
PCI local bus includes a bus mastering capability. The settings are Enabled  
or Disabled. The Optimal and Fail-Safe default settings are Disabled.  
Offboard PCI IDE Card  
This option specifies if an offboard PCI IDE controller adapter card  
is installed in the computer. You must specify the PCI expansion slot on the  
mainboard where the offboard PCI IDE controller is installed. If an offboard  
PCI IDE controller is used, the onboard IDE controller is automatically  
disabled. The settings are Auto(AMI® BIOS automatically determines  
where the offboard PCI IDE controller adaper card is installed), Slot1, Slot2,  
Slot3 or Slot4. The Optimal and Fail-Safe settings are Auto.  
If an offboard PCI IDE controller adapter card is installed in the  
computer, you must also set the Offboard PCI IDE Primary IRQ and Offboard  
PCI IDE Secondary IRQ options.  
Offboard PCI IDE Primary IRQ/  
Offboard PCI IDE Secondary IRQ  
These options specify the PCI interrupt used by the Primary (or  
Secondary) IDE channel on the offboard PCI IDE controller. The settings are  
Disabled, Hardwired, INTA, INTB, INTC or INTD. The Optimal and Fail-Safe  
default settings are Disabled.

AMI® BIOS USER’S GUIDE  
CHAPTER 3  
DMA Channel 0/1/3/5/6/7  
These options specify the bus that the specified DMA channel is  
used. These options allow you to reserve DMAs for legacy ISA adapter  
cards.  
These options determine if AMI  
®
BIOS should remove a DMA  
from the available DMAs passed to devices that are configurable by the  
system BIOS. The available DMA pool is determined by reading the ESCD  
NVRAM. If more DMAs must be removed from the pool, the end user can  
use these options to reserve the DMA by assigning an ISA/EISA setting to  
it.  
IRQ3/IRQ4/IRQ5/RQ7/IRQ9/IRQ10/IRQ11/IRQ14/IRQ15  
These options specify the bus that the specified IRQ line is used  
on. These options allow you to reserve IRQs for legacy ISA adapter cards.  
These options determine if AMI® BIOS should remove an IRQ  
from the pool of available IRQs passed to devices that are configurable by  
the system BIOS. The available IRQ pool is determined by reading the ESCD  
NVRAM. If more IRQs must be removed from the pool, the end user can use  
these options to reserve the IRQ by assigning an ISA/EISA setting to it.  
Onboard I/O is configured by AMI® BIOS. All IRQs used by onboard I/O  
are configured as PCI/PnP. If all IRQs are set to ISA/EISA and IRQ14 and 15  
are allocated to the onboard PCI IDE, IRQ9 will still be available for PCI and  
PnP devices, because at least one IRQ must be available for PCI and PnP  
devices. The settings are ISA/EISA or PCI/PnP. The Optimal and Fail-Safe  
default settings are IRQ3 through 7 are ISA/EISA. The Optimal and Fail-Safe  
default settings PCI/PnP.  
Reserved Memory Size/Reserved Memory Address  
Some ISA cards have ROM at 0C000h~0D000h segments, but in a  
non-standard format. So Plug & Play BIOS can’t detect it. The end user  
needs to set it up manually. Setting these options under this condition, will  
inform the BIOS which location and how many location is occupied.
