UNOFFICIAL BIOSTAR TPower I45 M/B

[Ace-a-Rue]

it sounds like your boot block code is corrupted...the only way to correct that is to use this AFUDOS.exe program (compliments of Rebel Haven) and flash from external DOS...i would bet the internal flash does not flash the boot block unless the updated bios has it coded to write over those blocks, like an update is added to the newest bios...the afudos should automatically flash the boot block...just watch the flash and it should announce it is flashing that section...if it does not, do a "HELP" command to find the appropriate switch.

also The Rebels Haven has the latest bios for a quick download.

here is The Rebsls Haven Biostar TPower Bios/Beta page: http://www.lejabeach.com/Biostar/TPI45/

if all this fails to correct your problem, my best guess would be the bios chip itself is defective..return the board for replacement or RMA it to Biostar.
