[Thinkpad] RE: CPU Upgrade for 770Z - Boot Error 127 with PIII500MHz and PC100 Memory

[Philip Kiff]

BREAKING NEWS!

I am now the proud owner of a 770Z PIII 500MHz which boots clean with base
128MB memory running at 100MHz.  No keystrokes required.

The solution I used was posted by Sharedoc over at wimsbios.com.  I take no
responsibility if anyone tries this and screws up their motherboard, and I
would not necessarily recommend that someone with my level of computer
skills get into the habit of editing their CMOS, but in my specific case,
with my specific machine, the process described worked flawlessly, and
exactly as described.

WARNING:
EDITING YOUR CMOS CAN PERMANENTLY DAMAGE YOUR LAPTOP!
PROCEED AT YOUR OWN RISK!
