Configuration Options

B-3

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:
