press F1 to enter setup: password 1234

Enter any ID to hardware Id.
Press 2x space bar when asked.

If 2x 5beep, it's normal.
I didn't do checksum but it must light up anyway.

ok.

I will reread and compare the 8M chip to orig dump to make sure its still stock.

I will then proceed to patch the 4M chip following ali sheikh's post and bin file.

Thank you both for your time and effort in helping me. Much appreciated

tried this...

screen doesnt even turn on.

put my original bios back on and screen prompts for setup as usual.

have reflashed the 4M bios again to try it after putting original bios back on to check everything still working.

I am getting 2*5 beeps after pressing F1 and the screen does not come on.
I have also tried an external monitor and keyboard but to no avail.

I did notice while i was in the bios prior to reflashing it this time that compuserve said it was enabled but not active.The supervisor password is definately on but I am not sure if the compuserve is on or not with it not being active.

any ideas ?????
