PhoenixBIOS beep code question

Posted on 1998-08-26
Last Modified: 2010-04-27
I have an Epson ActionTower that boots with no video output and beeps with a 1-2-2-3 error code. I checked Phoenix's website and that code indicates a ROM BIOS Checksum error.

My question is, what is a ROM BOIS Checksum error? And, what can I do, if anything, to fix this problem.

Thanks in advance,

Already done that, video is on board and memory is in. Any other ideas?

ROM-BIOS Checksum failure.  The ROM checksum value does not match the value encoded in the BIOS.  This usally means that the BIOS is bad.  Try booting the machine with nothing connected to the motherboard but the video card.  No hard drive, floppy, sound cdrom, anything.  Just the videocard memory and the power connectors.  If you still get the error you will need to replace your BIOS chip.  If you don't start adding one device at a time starting with you hard drive.  Unless you have a PEntium Motherboard you would want to just buy a new motherboard.

Blast the BIOS with an update.  If you can not locate one, buy a new BIOS chip.

The word "checksum" is short for "summation check".  This is a technique that your computer uses to determine whether a package of data is valid.  That package, which is actually a string of binary numbers, is added up and compared with an expected number.  When these two totals do not match, then (and I think that this has already been pointed out to you) it means that there is an error in your BIOS (basic Input/Output System). Most of the time it is a hard drive that is improperly configured, or the floppy drives have bad values. Another likely error place are the peripheral components.

Bios check sum error means bad content of the bios eprom, or bad logic interface to the bios chip. If you can find an exact replacement of the bios chip, try it. If it does not work you have a bad motherboard.
