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 JP16 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 JP16 to allow programming the Flash BIOS.
