laptop eeprom programmer

Hi!

I have recently been looking for a EEPROM programmer (For PC BIOS, is this flash?) to fix my laptop which i bought with a bad bios flash attempt. But I can't find one that I'm willing to put my time into.

Then I was thinking, what if I put an PLCC socket right on top of the BIOS chip on my laptop (which is a 32pin soldered plcc chip). and used a PIC to program it on board, does anyone know if that would work?

Or, if i used the same reversed socket to simulate a working bios (just deattach the chip-enable pin from original chip somehow). Do you think this would work?

Was going to use RS323 connection to the chip and make a simple app for it do download BIOS file to the PIC.

Any thoughts about this would be great! :)
 

All of BIOS on the modern PCs are Flash, it is for your exciting info.

But did you check your laptop BIOS? As in most of laptop, the BIOS is soldered directly on the motherboard and in general, it is hard to remove it without making it damaged.

However, there is a program to update/fix your BIOS, try to check up with your laptop manufacturer's website for this program and data for the BIOS, do not try by your own knowledge otherwise you may harm your laptop or make it useless.
