ISA I/O and Memory Configuration
allows setting the board’s ISA memory and I/O map.
By default the following I/O and Memory Ranges are mapped to ISA and NOT accessible for other
devices any more:
I/O: Range-0:
100h-17Fh
Range-1: 17Fh-1BFh
Range-2: 1C0h-1DFh
Range-3: 200h-27Fh
Range-4: 300h-33Fh
Range-5: 340h-35Fh
Memory: Range-0: C8000h-CFFFFh
Range-1: D0000h-DFFFFh
If a PCI device (e.g. on an external adapter) needs some of these ranges, the space has to be freed,
because the system is NOT Plug and Play!
Otherwise, if an external ISA card needs additional I/O or Memory space, the above ranges need to
be reconfigured.
Note:
You need to know exactly the resources that are needed by
external cards in order to setup the BIOS correctly! Otherwise it
may be that some cards do not work properly!
