Advanced Chipset Features
2.2.3.1 System BIOS Cacheable
Selecting "Enabled" allows caching of the system BIOS ROM at F0000h- FFFFFh, resulting
in better system performance. However, if any pro- gram writes data to this memory area, a
system error may occur. The Choices are "Enabled", and "Disabled".
2.2.3.2 Memory Hole at 15M-16M
Enabling this feature reserves 15 MB to 16 MB memory address space for ISA expansion
cards that specifically require this setting. This makes memory from 15 MB and up
unavailable to the system. Expansion cards can only access memory up to 16 MB. The
default setting is "Disabled".
DRAM default timings have been carefully chosen and should ONLY
be changed if data is being lost. Please first contact technical sup-
