Note: this post is a bit long and windy, but there's an hilarious tech support reply in the end...
A couple of weeks back I bought a new computer. Nice and fast, nice and cheap. In an effort to make the computer as up to date as possible, I decided to upgrade the BIOS. Using Asus (ugly-as-sin) Windows based flash utility, I upgraded to the latest non-beta BIOS. Unfortunately that resulted in a problem with my CPU fan, so I wanted to use the same utility to get me back to my original BIOS version. Turns out that it can't downgrade your bios. So instead I decided to try to see if the fan-problem was fixed in the available beta BIOS. Not only didn't that bios fix the problem, it also made my floppy drive inaccessible. 'A floppy drive?' you would say, 'what do you need that for?'. Well, for flashing your bios outside of windows...
Asus has a unique feature on their boards that will let you flash directly from floppy or cd, without booting into dos first. It's called EZ flash. Having no access to my floppy drive because of the buggy beta bios, I decided to use the CD that came with the motherboard and flash the BIOS version that's on it. That would be the safest, surest working option, right? Wrong!. Flashing went as planned (I'ld even say it went surprisingly well), but unfortunately the machine would not boot, not beep, not do anything... I thought something must have gone wrong with the flashing, but some googling learned me the BIOS on the CD must have been too old for my processor, and instead of running the processor at a low speed, Asus decided it was best to just shut down to prevent damage. Leaving me with a dead computer that would not boot, let alone let me update to a proper BIOS again.
Here's what Asus tech support had to say about it, when I explained what happened and requested a new bios chip: (this would be soo funny if it weren't sad)
Sir, Very sorry, we can't send you a alone bios chip.because the mb's an mac address, 1394 address are writen in the bios chip .if we send you a bios chip with program, the addresswill be error.
in the most , the chip is ok still, you could reflash the bios by hot-replug :, you could try with another ( with the same pcb version), please do as below:
- get the 'bad' mb' s BIOS chip
- relax the 'good' mb's BIOS chip.
- power on
- run the afudos under DOS , or the update bios in windows.
- remove the bios (don't short with the mb)
- insert the 'bad' bios in the socket, please note the direction of chip.
- flash it.
Because there have danger in this way,so I suggest you contact your dealer and let he do it fou you,I think he has the enough condition to do it.
if can'tdetect the bios chip or can't ! flash , maybe the chip is bad, please contact with your reseller for RMA.
Best regards !
A visit to a friendly computer shop was more helpful, and three days later I had a working setup once more.
