Upgrade Guide Updating the Flash BIOS This mainboard has two BIOS ROM chip options. It can use either of two programmable 'flash' EPROM chips, 5-volt or 12-volt, either of which you can update when BIOS upgrades are available. Jumper JP9 enables programming for the BIOS ROM chip. There are two settings. The default setting, which shorts pins 1&2, is for Write-Protect/Normal Read. The other setting, which shorts pins 2&3, is for Enable Programming. When you finish programming, always set JP9 back to the default Write-Protect/Normal Read setting. The following example illustrates this procedure.
