640 G4 BIOS Password need help unlocking Thanks
Tried RCunlocker said wrong chip (32mb)

Read post #26
Also if the tool "said wrong chip" it means it is the wrong chip. Find the second 16MB chip and use the tool with the dump from that chip instead of posting requests one after another. This is your sixth or seventh request this week, are you going to open a Hewlett-Packard dealership there?

Hi
I'm looking at post 21 and 22
where a member requested removal of password
from 32MB chip like mine and one of your team
removed it for him and it worked (post 24).
Can you do the same for me?
I had several that's why I made a good faith donation
on the 24th.

I resoldered the 32MB chip back onto the motherboard and then
used RCunlocker on the 16MB dump but just got a solid CAP's lock LED.
The motherboard went bad, a resistor near the 32MB chip broke off and
could not be resoldered back on.
