Memory Hole At 15M-16M
In order to improve performance, certain space in memory can be reserved for ISA
cards. This memory must be mapped into the memory space below 16 MB. The
choices are
Enabled
and
Disabled
.
System BIOS Cacheable
The setting of
Enabled
allows caching of the system BIOS ROM at F000h-FFFFFh,
resulting in better system performance. However, if any program writes to this
memory area, a system error may result.
