Epson Equity 286 PLUS - Manual (Page 45)

Setting the Shadow RAM
Your computer can access RAM (random access memory) faster
than ROM (read-only memory). The Shadow RAM feature
enables the Equity 286 PLUS to copy the contents of its system
BIOS and/or video ROM into RAM so it can perform certain
operations faster. It uses the RAM memory between the first
640KB and 1MB.
The SETUP Shadow RAM option lets you choose what to place
in the shadow RAM area:
System
Video
System and video
N o n e .
Select System+Video unless
you
have installed a memory
card or video card that provides its own shadow RAM (in which
case you can select just
System or just Video ). Select
None if you do not want to use the Shadow RAM function
Setting the CPU Clock Speed
This option lets you set the speed at which your computer’s
processor operates:
High speed (12 MHz)
Low speed (6 MHz)
Auto speed.
When it is running at high speed, the TURBO indicator on the
front panel is illuminated.
