[coreboot] Hosed ms-7032, I foolishly flashed the bios with a .700

Thanks for the reply, I used Flashrom as the utility and am quite comfortable using Linux and the command line. I got shot of my virally infected copy of Win98 sometime ago, I have my hard drive with Fedora 9 on my friends PC, it has the Flashrom utility and my backup.bin. It also has the same type of bios chip (PLCC), And its socketed!

My bios chip is a PLCC (not socketed unfortunately) and the info on the chip is;

Winbond W39V040AP

I've thought about unsoldering the chip but don't really have the proper tools. I could do it though, it will take ages because I'll have to take it real slow so and find something to use to take the heat away from the chip so I don't fry it, but I'm very patient and I think could do it (getting it back on might be a bit more problematic). 

My thought was to purchase another chip and 'kind of' place it on top of the other chip, but I'm not sure how this would go? I'd hope it would be a little like hot flashing, and the good chip would be recognized by the CPU and I could boot-up. It would then be a case of removing the new chip (making sure the bios is set to cashable first) and refashing with my backup.bin. But I don't know the 'bad' chip could interfere with it booting and cause it not to work. Another thought is this computer has something in the bios about 'booting' 'rom' and 'lan' I haven't fully looked into it yet, but if its what I think it is, its something to do with booting over a network, is it possible to do this with a CPU that has no bios?

I'm open and confident in trying all suggestions, and I love to learn.

Thank you
