System board options (continued)

Non-cache areas

Your computer automatically caches all of your memory except for the six non-cache memory blocks listed in the table below. You can define up to three additional, 16KB, non-cache memory blocks by selecting the User defined non-cache area(s) option and entering the block addresses. For example, if you install a network or bus-mastering option card, such as a SCSI controller, you should set the address blocks used by these boards as non-cache blocks to avoid any memory conflicts.
