Just curious: why would you like to change the serial number?

to prevent it from being detected as stolen?

1. extract the bios from the chip and save it as a file
2. learn assembler (<- the hard part)
3. decompress and disassemble the bios (IDA will help you)
4. locate the serial number
5. change it (<- that's the easy part)
6. come up with an algorithm that calculates the correct bios checksum
7. recompress and reassemble the bios

there might be tools at Compaq development dep. that could do all this (even with a nice GUI maybe). but i doubt that anyone would give it away or even admit that such tools exist.
