An attempted BIOS update that failed is bad news. Jumper settings won't help.
What to do next will depend on the features of the motherboard (sorry, I don't know about yours). Some motherboards have a backup BIOS you can invoke to let you re-try the flashing of the BIOS. Some don't - things get more difficult there - you may be able to get help from the manufacturer. I'd suggest looking on the manufacturer's website - they may even have a FAQ on the subject.
