z System BIOS Cacheable
Selecting Enabled allows caching of the system BIOS ROM at F0000h-FFFFFh, resulting in better system
performance. However, if any program writes to this memory area, a system error may result. The default value is
“Disabled”.
z Video BIOS Cacheable
This item allows you to change the Video BIOS location from ROM to RAM. Video Shadow will increase the video
speed.
z Video RAM Cacheable
Selecting Enabled allows caching of the video BIOS ROM at C0000h to C7FFFh, resulting in better video
performance. However, if any program writes to this memory area, a system error may result. The default value is
“Disabled”.
z 8/16 Bit I/O Recovery Time
The I/O recovery mechanism adds bus clock cycles between PCI-originated I/O cycles to the ISA bus. This delay
takes place because the PCI bus is so much faster than the ISA bus.
These two fields let you add recovery time (in bus clock cycles) for 16/8 -bit I/O. The default values are “1” for 8
Bit I/O Recovery Time and “1” for 16 Bit I/O Recovery Time.
z Memory Hole at 15M-16M
You can reserve this area of system memory for ISA adapter ROM. When this area is reserved, it cannot be
cached. The user information of peripherals that need to use this area of system memory usually discusses their
memory requirements. The default value is “Disabled”.
z Passive Release
When enabled, CPU to PCI accesses are allowed during passive release. Otherwise, the arbiter only accepts
another PCI master access to local DRAM.
z Delayed Transaction
The chipset has an embedded 32-bit posted write buffer to support delay transactions cycles. Select Enabled to
support compliance with PCI specification version 2.1. The options available are Enabled and Disabled.
z AGP Aperture Size (MB)
The field sets aperture size of the graphics. The aperture is a portion of the PCI memory address range dedicated
for graphics memory address space. Host cycles that hit the aperture range are forwarded to the AGP without any
translation. The options available are 4M, 8M, 16M, 32M, 64M, 128M and 256M.
z CPU Warning Temperature
This option lets you set the CPU temperature limit where the system will produce a warning indicating CPU
temperature has already exceeded. The default value is “Disabled”.
z Current System/CPU Temperature
These read-only fields reflect the functions of the hardware thermal sensor that monitors the chip blocks and
system temperature to ensure the system is stable.
z Current FAN1/FAN2 Speed
These optional and read-only fields show he current speeds in RPM (revolution per minute) for the CPU fan and
chassis fan as monitored by the hardware monitoring IC.
z Vcore/VTTP/VCC3/+5V/+12V/-12V
These optional and read-only fields show the current voltages in the voltage regulators and power supply as
monitored by the hardware monitoring IC.
