Cool, somehow badflash.com had slipped under my radar. Good to know.
I don't suppose you know of anywhere to get a bios chip for a linksys wireless router/switch? Got one with exactly the same problem.
If the chip is socketed, and you have the file with the firmware image, badflash.com might be able to make one for you. Probably worth e-mailing them to check. If you send them the old chip, it costs a bit less as well.

I think Asus also has it that you can buy new BIOS chips directly from them for a small price and also i think they allow you to send them the chip and they will reflash it for you for a smaller price. At least i remember seeing that somewhere when i had a flash go bad nearly two years ago.
Yeah, I looked around their site a little bit and didn't see anything. I was also looking for fast turnaround, so I can get on with this build; an RMA or getting ASUS to send me a replacement chip would probably take a while.
Also check ebay, might be able to buy a broken board with a good BIOS chip real cheap, cheaper than the chip alone. Thats what i did.
Good idea... I didn't think of that.
Sorry to hear that happened to you. So what did happen when you were flashing it?
Well, I decided to try and flash it using the flash tool that is built in to the BIOS instead of using a bootable disk. It appeared to read the image file OK, started to erase the PROM, then died with the message "Failed!". System was completely hung at that point, and wouldn't POST thereafter.
FWIW this is the first time I've ever tried to flash a BIOS without booting from a DOS floppy, and (not coincidentally?) also
the first time I've ever killed a motherboard BIOS. I think I will go back to doing things the "old fashioned" way.
If you know anyone who works at a high tech firm, they may have a PROM blower. Just give them the chip and the BIOS on a floppy and they should be able to program it for a beer
If I was still working in the telecom industry, I could've probably even done it myself; used to flash a lot of EEPROMs back when I worked on DSL/cable modem firmware.
Badflash.com was the path of least resistance though -- no need to ship the board or take the chip to someone to have it flashed... just do it all from the comfort of my desk chair. Lazy, huh?
I have seen designs on the web for simple PROM blowers driven off the parallel port. The hard part is getting the sockets, nice PROM blowers have funky universal ZIF ones.
Back when I was in college, a buddy and I rigged one like that. At that time (early '80s), PROMs required some weird-ass voltages during programming... 24V or something goofy like that. I remember we had a stack of 9V batteries wired in series, since we didn't want to spend the money to buy (or the time to build) a special power supply...
I've seen someone hot swap a BIOS chip. It actually worked but was kinda scary to even see it being done. Much safer to do it powered off.
Yeah... unfortunately if the existing chip is totally hosed, your options are rather limited. The idea is to boot off of a good chip, swap the bad chip in, and re-flash it without powering the system down.
I'm actually thinking of getting one of these:

It's essentially an aftermarket DualBIOS adapter... looks like you can also use it to do hot swaps without having to physically remove/insert the chip while the board is powered up. Considering that the device costs less than a single replacement BIOS chip, it is probably a worthwhile investment.
If the world isn't making sense to you, you're either drinking too much or not drinking enough.
