BIOS Setup
Memory Hole At 15M-16M
In order to improve system performance, certain space in memory can
be reserved for ISA cards. This memory must be mapped into the
memory space below 16MB. When enabled, the CPU assumes the 15-
16MB memory range is allocated to the hidden ISA address range
instead of the actual system DRAM. When disabled, the CPU assumes
the 15-16MB address range actually contains DRAM memory. If more
than 16MB of system memory is installed, this field must be disabled
to provide contiguous system memory.
