Something is amiss, Praetor. Whenever I boot the system up, the post will say something about bad checksum error. Okay, I thought, since I messed with the BIOS, then I'll just buy a new CMOS battery. I configured all the settings with my written paper reference and saved it, but some BIOS options are different, all the options of the Boot Device Priority. It is just that the BIOS used to list Boot Device 1 2 3 4, but now it is some ISA enable bit, or disable option. Still the same check sum error. THE BIOS EVENT logging says that it doesn't detect a keyboard, or it has some problem with it.

To load Windows from the POST error page, all I have to do is F1 into BIOS setup, exit without saving the BIOS, then let it run for a few seconds because it still thinks I'm trying to flash it. Then when it says cannot locate floppy with files (presumably for flashing), I just hit Ctrl-Alt-Delete, and Windows loads fine.

So, even though the Intel Auto-updater failed to flash the BIOS, could something be amiss? By the way, when I first turned the computer back on after replacing the CMOS battery, it said CMOS battery low. That isn't right. After configuring and saving the BIOS, it just lists the same check sum error and you know what I do then.

Please Praetor, give me some guidance. I don't want to have to replace the motherboard or keyboard or floppy drive, or some other device. Please, what has happened? I thought the manufacturer locked the BIOS memory so it couldn't be replaced or changed with some other BIOS?

Could the CMOS memory be corrupted as a result of attempted and failed flashing?

UPDATE: Still the same error, I just keep bypassing it. I reseated the CMOS battery, put back the BIOS settings, still the same thing. I made a boot floppy with an unzipped Intel BIOS flash for my motherboard. Some write-protect and BIOS string error stopped the utility program from working, so no flash. I think it is only flashing half way. 50% of BIOS being updated...........update unsuccessful, write error, string error. So, ain't much changed. I think I'm still running on the old BIOS.......but maybe some things have changed because of a partial flash. Hmmmm, I guess it's the annoying floppy read noise and stupid Ctrl-Alt-Delete I have to do to by-pass the computer's POST checksum error and the 'searching for MAC address' error and system halt.

Everything works, just more annoyances now.

Praetor

while its *generally* a good idea to go with all the updates and stuff, many people (tyically power users and those with older systems) will have more problems after installing sp2 than before.

well the first time that happens, reset the BIOS to failsafes and then when thats done, go through and tweak it again (a bit more conservative tweaking if needbe). if it happens a lot, that coud be a sign of failing cmos battery or something more serious

try doing a cmos reset (remove battery + flip jumpers)

dunno where you said it if you did, what OEM do you have? regardless you should be able to do a hardreset

yes but *generally* only if

• power dies duriing the flashign or something to that effect
• you force-flashed the wrong bios

can you do a register dump? see questions101 for how to do it via CPUz.

I have already done that. It is a .txt file on my desktop called BIOS readme.
This is the work around for the checksum error:


CMOS Error On Reboot --

System Behavior:
When the system reboots, the following error
occurs:
CMOS/GPNV Checksum Bad
Press F1 to run SETUP

Resolution:
None. Use the following workaround:
1. Press F1 to enter BIOS.
2. Press ESC.
3. When the message, "Discard changes and exit
setup now" appears, select YES.

See my next post for all the pictures.

1.) Start up after floppy read noise.

2.) After F1 and exiting BIOS, put in BIOS flashing boot disk floppy. Automatic read:

3.) Set up utility menu 1

4.) Choose option:

7.) The "Updating BIOS" loading bar only for 2 seconds (no pic)

8.) String error:

Must then hard shut down and turn back on via case power button.

I found this on the Intel page, I can't tell if you have tried this or not: If the error message "CMOS/GPNV Checksum Bad.Press F1 to Run SETUP“ appears during boot, then press [F1] to go into the “BIOS Setup Utility", press [F9] to load setup defaults, and then press [F10] to save and exit.

Yeah I already did. Please note that the CMOS doesn't save any settings (via checksum error) so every startup is by default settings.

NOTE: This is what happens everytime after I bypass the error message:

http://img.photobucket.com/albums/v4...b/000_0071.jpg

After this, I Ctrl-Alt-Delete and Windows loads fine.

I wondering...is it trying to boot from the (Road Runner) network? I mean, an MAC address? My cable modem?

Byteman

I believe the firmware is modified by the manufacturer, (Gateway in your case), they have all the firmware updates for thier particular models. I suggest you use their update not intels.

Edit: lets see if this link works...

That certainly looks like a boot from network error, since your checksum problem seems to prevent you from saving anything you probably can't turn off boot from network.

We did it guys!! The factory BIOS worked! It was stuck at a DOS password screen, but I took out the battery and put it back in to reset it.

Thank you Byteman for giving me the link to Gateway's site. I re-flashed it with the factory BIOS and EVERYTHING is back to NORMAL! The BIOS has been reconfigured by me.

No more errors, no more CMOS problems, no boot from network, and, we succeeded.

It has occured to me that the original BIOS already had support for 48-bit LBA.

A huge thank you goes out to everyone who helped me. This challenge has been a great learning experience for me.

Thank you.

HI and BOY am i glad i found this forum post, im having the same problemsEXACTLY, and same MOBO and whats not, question is did u download the El PASO 2 mobo bios or 1, dumb question, but tryin not to make things worse, i have el paso 2 as well. and all u did was extract to floppy restart, and all was good. I was rdy to flash the bios, AND GATEWAY IS trulyyy not all togeather there. LIVE TECH was a waste of (combined) 120 summtin odd minutes. Also give some details about the password...ahh u know what i got it..damn, and to think im a+ certified...or was...what u learn today is outdated yesterday
