IBM thinkpad t61 bios hacking

**dave11674**

hi guys

my t61 just went tits up
updated bios and now i get password prompt

ive read up and managed to dump the eeprom
loaded it into IBMtools 2.1 lite but not showing the passy
i can see some ascii text so i know its dumped ok

ive checked the lines where it says the password is kept
but its all jargon
so thinking it encrypted

any1 got any ideas or tools

thanks
dave

But be warned this can be dangerous.If you are not capable of doing this right dont try it.

Try decode it with IBMpass if you get RF, it's TCPA locked, you will need a patched eeprom dump and a eeprom writer.
Good Luck
