Advanced Chipset Features

This section allows you to configure the system based on the specific
features of the installed chipset. This chipset manages bus speeds and access
to system memory resources, such as DRAM and the external cache. It also
coordinates communications between the conventional ISA bus and the PCI
bus. It states that these items should never need to be altered.
The default settings have been chosen because they provide the best
operating conditions for your system. If you discovered that data was being
lost while using your system, you might consider making any changes.
System BIOS Cacheable
Selecting Enabled allows caching of the system BIOS ROM at
F0000h~FFFFFh, resulting in better system performance. However, if any
program is written to this memory area, a system error may result.
Ø The Choice: Enabled or Disabled.
Video BIOS Cacheable
Selecting Enabled allows caching of the video BIOS, resulting in better
system performance. However, if any program is written to this memory
area, a system error may result.
Ø The Choice: Enabled or Disabled.
Memory Hole At 15M-16M
You can reserve this area of system memory for ISA adapter ROM. When
this area is reserved, it can't be cached. The user information of peripher-
als that need to use this area of system memory usually discusses their
memory requirements.
Ø The Choice: Enabled or Disabled.
