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.
