G41 will not go into BIOS config

[solidpro]

HI Everyone

I'm going through a pile of G4x machines (and will be selling one soon).

I have one G41 which works perfectly well but will not go into the BIOS. When you switch on, it says 'press blue access IBM button or press enter' and both of those key presses makes the message instantly disappear, registering it's noticed, but then.... it just carries on booting.

No matter, what I do, it then just ignores me! It's really quite rude.

I replaced the CMOS battery, I removed the HDD, I even successfully updated the BIOS using the original IBM floppy upgrade which works perfectly fine on the other G41...

Any ideas? I really don't think it's the keyboard - for example if I keep hammering the 'access IBM' button, after about 5-10 presses, it beeps at me like 'leave me alone'....

Thanks
