Ok this is the deal, i have an IBM thinkpad A21e that gives me an error 0175 when i start up. Now i know what the error is and i know the source and cause and possibly how to fix it. Now my question is, i have managed to Dump the BIOS data is there any way i could edit that particular block of that code to possibly fix this thing? and also is there another alternative to this(like taking a hammr to it?)

As you know, the BIOS has been corrupted. I'm amazed you got the data out of it. Without knowing how IBM computes the CRC, you can't find the bad block. Even if you find the bad block, you still don't know how to fix it except by getting the image elsewhere.

IBM's hardware maintenance manual for the A21e says the system board has to be replaced, but they don't want technicians spending hours on these things. Here's the manual:

There are some on eBay who claim to be able to fix this for $125 or so, without replacing the system board. Maybe he has a machine that will clip onto the BIOS chip.

Theoretically, you could re-program the device. How to do it is the key. You can't do it in-circuit because the computer won't start, so you have to remove the chip, which is soldered in. Then you can program it in your handy EEPROM programmer, if it will take the particular chip.

Go to http://www.pc.ibm.com/support and get the BIOS for your particular machine. There will be several binary files that might be the BIOS. Analyze what's left in the BIOS to see how they differ from the files you get, reprogram the chip, solder back in, and away you go.

Or if you've gotten the BIOS data out of the chip, maybe you could run the FLASH updater from DOS.

Here's someone who claims to be able to do this with another laptop and a simple board you make yourself:

He charges a fee of US$76 to supply the kit. This may be your best bet.

Have you tried any of my ideas? You have quite a few options for both trying to fix the chip and for replacing it.

Do you have any more questions as to how to go about doing any of these options?
