Reset BIOS settings for PCIe.

Asus M3A motherboard
Windows 7
Trying to test a USRobotics PCIe 56k modem for use in a condo customers door entry system.
Didn't work at first so I removed it and rebooted into the BIOS and enabled PCIe. (Big mistake, wasn't thinking).

Now boots with no video, 1 long, 3 short beeps, and no way to get back into the BIOS to reset.

I took the CMOS battery out and replaced hoping that would reset settings to default disenable the PCIe.

No jjoy.

2 short beeps, a series of long beeps (about 8?) than 2 long.

Is there anyway to reset this?

Thanks.
They're trying to get a new mobo working.
This PC was working till I changed the BIOS setting.
I'm using a GTS 8800 which had been working perfectly until the BIOS change.
I have everything "physically" back to normal.
My guess is that the PC is now looking for a PCIe display adapter and not finding one.
The GTS 8800 is plugged into the PCIEX16_1
Here's the beep reading:
"Display Memory Read/Write Error       Video adapter is missing, incorrectly seated or has faulty memory".
I thing its looking for the PCIe and not finding it.

BTW, this isn't a Dell.
Totally home grown.
Here's what I found on a 3 year old Yahoo forum:
