CHAPTER 1 INTRODUCTION

1-1

The MS-6117 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).

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 write­combining with buffering strategy for write operation. This is useful for
frame buf fering. 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.

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.

AGP Aperture Size

This option determines the effective size of the graphics aperture
used in the particular PAC configuration. The AGP aperture is memory­mapped, 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 T ime)
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 GA T 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.

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.
