2.5.1 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”.
Note:
DRAM default timings have been carefully chosen and
should ONLY be changed if data is being lost. Please first
contact technical support.
