Block protection of Flash ROM

Hello all, Recently, we had a bad problem of block protection. You know, our programmer can't protect the 29F002 flash ROM, and our motherboard doesn't have 12 volts output for BIOS. So, from the preceding phenomena, it seems impossible to get a protected BIOS! Unfortunately, it happened. Anybody could tell us what happened? Is it the problem of material quality? Thanks to provide your experiences and comments.
