Sony Vaio PCG-FXA63 BIOS corrupted

Recommended by Wim's BIOS...

Hello.
I have a PCG-FXA63 notebook with corrupted Bios. I was trying to update my bios when the power shut off.
I try to restore it with crisdisk and a Parallel Port update key (see this post), I ear beep´s sounds on my laptop while accessing the floppy drive. After maybe a minute the process will stop, but the Floppy ligth dosent goes off. I thought the process was done but after removing the floppy drive and the update key still, nothing happened, no images on my monitor.
I don’t know what I’m doing wrong, could be the crisis disk version? Or the Bios file?

I would be very grateful if somebody could give me useful information.
Thanks.

Did you already consider a fresh motherboard from eBay?
