BIOS Updates forum

I bought this laptop for spare parts and it does powers up, vent's up, hdd's up, flashing 2-3 sec cdrom but it does not post. So i dissasembled it, desoldered the bios chip and read it with willem programmer, but i don't know if the rom file is corrupted or not.
How can i check if my rom image is good or bad ?
Averatec and other manufacturers that made similar model does not provide any bios support.

Thanks in advance
