If you have a power cut during BIOS update you will end up with bricked motherboard.

depends how far the bios got before the power went out. some older mb have a bios recovery in them if they still have some code on them. some will do it if a usb or cd with the flash rom is in the see at post the cd-rom or floppy light come on..
if not sometime there a keystoke to force a reflash.
if not you have to contact the mb vendor to see if they can send you a replacement bios chip.

If you can boot to DOS bootable CD then re-flash BIOS. Otherwise you will have to flash using motherboard's SPI connector. Search Youtube for SPIPGM2.exe and Google SPIPGM
