Setting The Cache/Dram Control Options - Epson Equity 4 Setup Manual

Setting the Cache/DRAM Control Options

Your system can use some of ifs 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
for your system. These options also control how much extra
extended memory you have available.
The following fable identifies the available options and the
effect they have on your system's extended memory.
