The MMIO address selected must not be assigned for use by
any other adapter or option and cannot be the same as the
RAM address for this adapter. If a system resource conflict
continues, you may have to change the settings of other
adapters or options that are in your computer.
Shared RAM Page Size and Address Range
There are 30 possible blocks of memory that can be assigned
for accessing the RAM located on the 3C689 adapter. The
factory default RAM size is 16 KB and the address location is
D0000–D3FFF.
RAM paging allows the software to access all 64 KB of RAM
on the adapter one page (16 KB) at a time, while using only
16 KB of computer memory space. RAM paging is available
for all 16 KB address ranges.
If a conflict continues, you may have to change the settings
of other adapters or options that are in your computer. The
30 RAM address ranges are as follows, with the default in
bold
