Chapter 4: BIOS Setup
Video Memory Cache Mode [UC]
USWC (uncacheable, speculative write combining) is a new cache
technology for the video memory of the processor. It can greatly improve
the display speed by caching the display data. You must set this to UC
(uncacheable) if your display card does not support this feature, otherwise
the system may not boot. Configuration options: [UC] [USWC]
Memory Hole At 15M-16M [Disabled]
This field allows you to reserve an address space for ISA expansion cards.
Setting the address space to a particular setting makes that memory
space unavailable to other system components. Expansion cards can only
access memory up to 16MB. Configuration options: [Disabled] [Enabled]
Delayed Transaction [Disabled]
When set to [Enabled], this feature frees the PCI bus when the CPU is
accessing 8-bit ISA cards. This process normally consumes about 50-60
PCI clocks without PCI delayed transaction. Set this field to [Disabled]
when using ISA cards that are not PCI 2.1 compliant. Configuration
options: [Enabled] [Disabled]
Onboard PCI IDE [Both]
This field allows you to enable either the primary IDE channel or
secondary IDE channel, or both. You can also set both channels to
[Disabled]. Configuration options: [Both] [Primary] [Secondary] [Disabled]
