If you use DTK or Phoenix 1.1002 BIOS, you can enable or disable
these two shadow RAM functions through your BIOS setup.
If your BIOS does not support shadow RAM, you may use the program
on the diskette included with this mainboard to set up the shadow RAM
driver. Follow the steps below:
The shadow RAM utility is now installed. Your AUTOEXEC.BAT file has
been modified by the installation program. The shadow RAM function
will automatically activate after you reboot your system.
If you want to update your shadow RAM utility, you may run the
"SHADOW.EXE" file and modify shadow RAM as you desire.
Note:
1. Because 128K of DRAM is reserved for shadow RAM, the switch
setting for the starting address on the PEI-306 should be xMB + 256KB
with x representing the onboard installed memory size.
2. if your adapter uses extended memory area as non-cacheabie
memory in the same way as dual-port memory, you have to locate the
non-cacheable memory after the cacheable area is set by means of
SW1-1, SW1-2 and SW1-3.
3. if your adapter BIOS is located at 0C8000H-0CFFFFH (within
0C0000H-0CFFFFH) and cannot be cached, you should move the
address to a non-cacheable area like 0D0000H-0DFFFFH or disable
video shadow function..
4. Cacheable area means physical 32-bit memory installed area and
shadow RAM area (0F0000H
installed.
