BIOS screw up

[DSM]

Think I screwed up my settings.
Was installing new printer/copier on win2000, had to change paralel setting to ECP, well I did more than that. I set to Optimal Settings and now I get nothing. The compter runs up but I have no picture. Monitor seems like it is in sleep mode. Tried yanking the battery from motherborad to see if it would reset to default settings, but alas nothing.
What can I do?
Thanx

Clear CMOS

How do I do that? All help is greatly appreciated.

Most motherboards have a jumper to do this. It depends on the model of motherboard.

Or you could use this debug routine:

-A <Enter>
-MOV AX,0 <Enter>
-MOV AX,CX <Enter>
-OUT 70,AL <Enter>
-MOV AX,0 <Enter>
-OUT 71,AL <Enter>
-INC CX <Enter>
-CMP CX,100 <Enter>
-JB 103 <Enter>
-INT 20 <Enter>
-<Enter>
-G <Enter>
-Q <Enter>

Or you could use this debug routine:

..but as he can't get a screen up, probably not.

Not sure if this is significant, but was working on it last night and got the computer up but then I got:
Press F1 for setup
Press F2 to startup with default settings
I tried both and the computer let me into CMOS but then would not reboot.
I switched video cards from AGP to PCI and again got the same thing.

I would like to try to clear the CMOS, but can someone tell me. After I set the jumpers, what do I do then?

If you can get into SETUP, load safe defaults.
