I switched my ram sticks as i realized i was only using one channel. Booting up i got an error saying BIOS ROM checksum error. I can not access the BIOS settings as it says Award BootBlock BIOS v1.0. It then tries to load my CDROM and my Floppy drive. It will load awflash.exe from the CD ROM to try and update the BIOS. It then says ""see if lockout jumpers are set to correct" and it will not update from there. I have removed the battery and used the jumper to reset the BIOS and nothing. I burnt the AWflash.exe and the asus1008 update file to the CD. It says to use a floppy so im not sure if thats my problem. My specs:

Asus A8N-E
athlon 34 3200+
OCZ 1024 dual channel 2-6-6-8


PS i have the ram in 1 and 3 now. I had it in 3 and 4 originally. Switching it caused the problem, switching it back fixed it. I then removed the battery for 20 seconds and reset and now the 3 and 4 setting wont work. Thanks!

You have prob scrambled the bios not by RAM misplacement but by insufficient voltage or too tight settings in dual channel low latency hi-perf RAM, or perhaps even incompatible RAM in dual for the mobo.
The crash free CD has the original shipped bios on it to recover to.
The message you are getting normally means you have cmos jumper on wrong pins
Should be on default 1-2 when flashing ("left position")
Never do anything with jumper off.
Nothing needs to be "burnt to the CD", its all there set to auto boot and run

But first:
Use only one RAM stick for now, in B1 slot, third slot from CPU
A1 and B1 is single channel
A1 and A2 is dual channel mode (page 29 of FULL 120 page manual)
You should run the OCZ at at least 2,8V, and at relaxed latency to start off.
If you have a cheap hi latency RAM stick laying around - thats even better for the bios recov
Go to bios and set to failsafe defaults, if you can get in.
Shut down, take out battery, short CMOS pins to 2-3, turn rocker switch on PSU to 0, unplug PSU from wall, wait 24 hours.
Put battery back in, plug in PSU, put rocker switch on 1, place cmos jumper back to 1-2 (default), boot to bios and again set to failsafe defaults and see if it will boot.
Booting to shorted cmos will screw up bios.

The above is to see if you can recover bios without flashing (prob not, but worth a try)
Its important to firsy boot to crappy RAM that is not so demanding.
If this fails come back and I will show you how to set up manual flash from floppy

There is also the EZ flash utility built into chip (page 54 of manual)
You only have to download and put latest bios file ONLY to a floppy
With CMOS jumper on 1-2 (default) you just have to press alt + F2 while booting
Asus really went out of its way to help with bios probs
