Windows 7: Corrupted BIOS?

Corrupted BIOS?

Right, I have a huge technical problem, and desperately need some help. I sincerely hope that you guys are able to help me in some way.

Basically, I have an Acer T180-UB7Z here, and it was working fine, par the bad ram. All was fine, until I tried to update the BIOS. I downloaded the most recent bios update for that specific model, from Acer's website, so I know it wasn't a bad copy. I ran the updating tool within Windows, and tried to update. The update failed with an error saying something along the lines of 'could not erase - the hardware may be write protected'.

Thinking the bios was write protected, I assumed that the updater never changed it in some way, and so didn't think to revert to the backup I made. However, when I restarted the machine, it now fails to boot. The BIOS claims to be a 2007 version, which I downloaded, even though it supposedly never installed (it used to say it was 2006). It hangs at "Verifying DMI pool data". I googled the situation, and discovered that it is a fault with the motherboard, that the onboard bios flasher is faulty, and that everyone who has ever tried to update it has received the same problem, and there is virtually nothing that can be done within the machine to repair it.

The machine can not boot from CD, hard drive, removable devices etc, since Verifying pool data happens before this, and cannot be skipped. The bios settings can be accessed and changed, but I've read that no combination of settings will work in this situation. Basically I need some method of flashing the bios externally, without using the machine in question. I have tried clearing the CMOS, but that did nothing. Acer cannot repair it since it is out of warranty, and I have no idea what to do.

I was hoping that there is a method of flashing the bios without any special hardware, but without booting the machine in question. My dad suspects that the local computer shop would be capable of doing this, but that they would charge me a lot.

I'm really stuck here. The machine is inoperable. I need it up and running again ASAP, for as little money as possible.

Literally any help is appreciated.

Check the manufacturer's website. Some BIOSes have a failsafe feature that allows you to return the BIOS to factory code in the event of a failed update. What it's called will vary from manufacturer to manufacturer, but look for words like "failsafe" "bootblock" and such.

I do hope your board / BIOS supports that. Otherwise it's pretty much a paperweight.

More like an expensive paperweight to repair. If you can't recover the bios yourself as suggested by pricetech, you may have to send it in for repair.

As to whether your warranty covers it, that's another story.

Good luck.

@Pricetech - there is a bootblock setting, enable or disable, but I'm not sure what it is, how to use it, or if it was even enabled or disabled at the time of the failed update. Any ideas?

@Pebbly - thanks a lot for the research. It's appreciated. Also, you mentioned ASUS, was that correct, or were you confusing it with Acer? :S

@Sygnus21 - I'm pretty sure the machine is out of warranty, as the Acer support person I talked to said that my serial number on the sticker was invalid.

Is there any hardware that could flash it without using the onboard flasher? (which caused the problem. :/)

Thanks Pebbly. I'm having a look now.

Is there any known way to bypass Verifying DMI pool data? Can't boot from USB, CD, or hard drive, and I have no floppy drive available. Tried clearing CMOS, but I'm under the impression that there are 2 halves of different bios versions in there at the second. Some of the original 2006, and some of the 2007 update.

Edit - Never mind. I realise now that I asked a rather silly question there. It's been a long day. :P

If I purchased an internal floppy disk drive, could I boot from that before the machine starts to verify the DMI pool data?

You're not going to get around that. Without the DMI (BIOS) info the machine is toast. Sorry
