Installing and Configuring the JX30WB

JX30WB System Board

4-8

Micronics Computers, Inc.

Setting the CMOS Main Screen
(Cont'd.)

External Cache Mode

This option selects the type of level 2 cache installed in the
system. The choices are WRITE-BACK or WRITE-
THROUGH.

Setting the CMOS Extended Screen

System BIOS

The system BIOS allows you to “shadow” the BIOS on the
system board. Choosing SHADOWED & CACHED copies
the system BIOS into RAM for faster execution and makes
the memory region cacheable. This allows you to take
advantage of the high-speed 32-bit bus and the 70
nanosecond RAM. Choosing SHADOWED copies the
system BIOS into RAM, but does not cache any memory
region. You can also select DISABLED.

Video BIOS

The video BIOS allows you to “Shadow” the BIOS on the
video card. Choosing SHADOWED & CACHED copies
the video BIOS into RAM for faster execution and makes
the memory region cacheable. Choosing SHADOWED
copies the video into RAM, but does not cache any memory
region. You can also select DISABLED. Some video cards
cannot be shadowed, so this selection must be set to
DISABLED.
