Phoenix-Award BIOS Utility 40
3.7 Advanced Chipset Features
This section contains completely optimized chipset’s features on the
board that you are strongly recommended to leave all items on this
page at their default values unless you are very familiar with the
technical specifications of your system hardware.
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 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.
