Setting the Cache/DRAM Control Options

Your system can use some of its reserved memory as extended

memory and still allow shadowing of both the system and

video BIOS. Depending on the options you select, you can

make 0,256, or 384KB of additional extended memory available.

Three Cache/DRAM Control Options on the Status page of the

SETUP program work together with the Shadow option on the

Options page to determine what shadowing, if any, is enabled

for your system. These options also control how much extra

extended memory you have available.

The following table identifies the available options and the

effect they have on your system’s extended memory.
