Memory Hole At 15M-16M
Enabling this feature reserves memory address space (between 15 and 16MB) to ISA

memory unavailable to the system. Expansion cards can only access memory up to 16MB.
The default setting is “Disabled”.

for accessing data. Then the master bus control will go back to PCI again.
