Hello,
I wanted to upgrade the BIOS using the service diskette
donwloaded from the IBM web site on my Thinkpad 760XD but the
machine refuses to do it because my machine has dead batteries.
I bought it second-hand knowing this limitation. I don't know
where to buy fresh batteries so I am seeking for alternative solutions.
Do you have any idea how to bypass this check? I know it is for
safety reasons since the system board could damage if a power
interuption occurs during update. I have two ideas, maybe
someone could expand them.
1. The service diskette is essentially a boot disk which
contains the following files:
Command.com
Config.sys
flshbios.sys
Ibmbio.com
Ibmdos.com
Updtflsh.exe
Userint.exe
Utilinfo.exe
$0022000.fl1
I suspect that one of the com or exe files does the check and provides
the user interface, while another one does the update, so renaming
some file could do the job. I know it might be dangerous...
2. The battery is an intelligent one so some hacking could make it
being recognised by the system as charged.
Any help or ideas would be appreciated!
