Updating the Flash BIOS
This mainboard has two programmable BIOS Flash EPROM op­
tions. One has a "boot block" feature, the other doesn't. You can up­
date either of them when BIOS upgrades are available.
Jumper JP24 enables programming for the BIOS EPROM boot
block. There are two settings. The default setting. Boot Block Protect,
with pins 1&2 shorted, prevents boot block programming. The other
setting. Boot Block Programmable, with pins 2&3 shorted, allows pro­
gramming to install a new BIOS including a boot block area.
Note: The Flash EPROM with no boot block area does not require
the use of jumper JP24 to allow programming the Flash BIOS.
BIOS With Boot Block Update Procedure
1. Set JP24 to the Boot Block
Programmable setting.
2. Refer to Chapter 3 for instruc­
tions on using the Flash Memory
Writer Utility to install a new
BIOS file in the flash chip.
3. When you have successfully
installed the new BIOS, set JP24
back to the Boot Block Protect
setting.
