P/I-P55SP3AV User's Manual Updating the Flash BIOS This mainboard has two programmable BIOS Flash EPROM options. One has a "boot block" feature, the other doesn't. You can update 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 programming 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 JP24 short pins 2&3 Use FMW to update BIOS JP24 short pins 1&2 1. Set JP24 to the Boot Block Programmable setting. 2. Refer to Chapter 3 for instructions 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. 2-10
