I always new it was risky to upgrade my BIOS b ut had a crack anyway. heres what i did:
1) Using AFLASH from BootDisk loaded v1005a of BIOS which is AMI. I renamed it ROM
2) Checksum error on reboot asking for original BIOS ROM. I kept same disk in and forced it to reread v1005a file
3) NO POST(nothing on monitor keyboard).. No beeps.. nothing

I think this is the System Boot failure prob warned about in manual. I've tried clearing CMOS, powering down (although not for two days) and kicking the bjesus out of the PC. Nothing gets me to POST. I thought that the EZFalsh was supposed to helpl me here but cant get that far.

Any ideas?

Hi gunsu69, and welcome to the forum!

You're right. Updating a BIOS is like doing brain surgery, it's something that should never be taken lightly. Not saying you did, just advice for the others reading this.

If you truly used AFLASH as you said, that's bad!... hopefully you meant AFUDOS, and just made a typo. If not, it likely explains why your mobo is now dead. (Btw I don't see a version 1005a for your model on the download site; I see a v1005, and v1008 is the latest.)

For your model mobo, the manual says to use AFUDOS, which is a completely different tool. Generally we use AFUDOS with the AMIBIOS and the P4 boards; and we use the older AFLASH with the Phoenix BIOS and the AMD boards; though I'm not sure that's a hard-and-fast rule. It's not a user choice either: the correct tool MUST be used or damage can occur. Sadly, Asus' own instructions have been rather confusing and misleading over the years, about which tool to use when and on what.

Well yes and no. I understand your frustration. I think we are finding "Crash Free BIOS 2" is not as bulletproof as we would like to hope. Have you tried the EZFlash procedure outlined in Section 2.1.5 of your mobo manual, and it hasn't worked? I think that it can work in many cases, providing the mobo hasn't been flashed with the wrong BIOS or using the wrong tool; in those cases and other random cases, EZFlash may not work.

Also note that from what I can tell, EZFlash is really only designed to reapply the original FACTORY Bios, it is not really meant for "updates", although Asus does use that terminology in the text. AFUDOS is the tool for updates, and it is regularly updated, unlike the hardware-resident (we think) EZFLASH.


One decent recovery option is to call Asus and have them send you a new BIOS flash memory chip in the mail, I think it costs around $15 U.S.. The chip installs in the lower left corner of your mobo, next to what would be the WIFI slot if it were loaded. Be extremely careful prying out the old chip, after noting the exact orientation you need to get under it and gently pull straight up; use a proper tool, or at least a paper clip with the tip carefully bent into a tiny "L" with pliers.

Another option might be to sweettalk Asus into taking your mobo back on an RMA, as the only thing wrong with it is probably the bad BIOS code. If they want to keep you as a satisfied customer, they will probably do the exchange. BTW if you break the BIOS chip socket or scratch a trace trying to get the old chip out, they'll be much less likely to oblige for free. So be careful.

Hope this helps,

That's to be expected. The OS on your HDD is looking for all the devices onboard your old mobo, at their exact addresses. Since you switched mobos, you'll need to do a Repair Install, or a reinstall if that doesn't work.

Pop the OS Install CD back in, and boot it. Let the OS Setup discover the existing OS installation; it should offer to (R)Repair it. Hit R, and go from there. This should reapply "standard" drivers to cover the new mobo's basic onboard components. Then after bootup to the desktop, you should reapply the chipset drivers, then all the other drivers compatible with your new mobo.

Hope this helps,
