Enabled
Video shadow is enabled
Disabled
Video shadow is disabled
C8000 - CBFFF Shadow/DC000 - DFFFF Shadow
These categories determine whether option ROMs will be copied to RAM. An

The Choice: Enabled, Disabled.
EDO DRAM Speed Selection
The DRAM timing is controlled by the DRAM Timing Registers. The timings
programmed into this register are dependent on the system design. Slower rates
may be required in certain system designs to support loose layouts or slower
memory.

EDO CASx# MA Wait State
You could select the timing control type of EDO DRAM CAS MA (memory
address bus).The choice: 1, 2.
You could select the timing control type of EDO DRAM RAS MA (memory
address bus).The choice: 1, 2.
SDRAM RAS-to-CAS Delay
You can select RAS to CAS Delay time in HCLKs of 2/2 or 3/3. The system
board designer should set the values in this field, depending on the DRAM
installed. Do not change the values in this field unless you change specifications
of the installed DRAM or the installed CPU..
The Choice: 2, 3.
