board that you are strongly recommended to leave all items on this

technical specifications of your system hardware.

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
Enabling this feature reserves 15MB to 16MB memory address
space to ISA expansion cards that specifically require this setting.
This makes the memory from 15MB and up unavailable to the
system. Expansion cards can only access memory up to 16MB.
