Chipset - Intergraph TD-x20 Setup Manual

D x 000, 16K Shadow
When the system boots, the BIOS code on ISA adapters is used directly from ROM
(Disabled, the default setting), or it is copied from the board's ROM to system RAM.
Overall system performance improves when copied to RAM (Enabled). When set to Cached,
the BIOS is copied to RAM and cached, further improving performance. An ISA board
BIOS executes faster from system board RAM than from the ISA board ROM. All of the
ISA Adapter ROM parameters are set to Disabled by default.
