P5B-ASUS-2104 tested ok

BIOS .zip 609 KB Shared

BIOS for the ASUS P5B desktop motherboard, version 2104, marked as tested and working. Desktop boards of this era often use socketed flash, so the image can be written with a programmer or a hot-flash method if the board will not POST. Confirm the exact P5B variant, since the Deluxe, SE and plain models use different files. Also check that the image size matches the flash chip. Saving the current chip contents first gives you a fallback if the write fails.
