Plausible BIOS recovery method as a last resort ...


So, this doesn't have to do with Linux, but there have a few threads here about people permanently bricking their computer mobos with a bad BIOS flash, which does happen. Now, if all other methods fail, like making a recovery disk and pressing special keys and all that, here's one last option that involves the Arduino (which you may or may not know about):

EEEPC 701 (4G) - Recovering a bricked BIOS with an Arduino
http://forum.eeeuser.com/viewtopic.php?pid=718910

Pretty cool, IMO. Maybe I should get one of those just in case.

P.S.

My last resort to recover from a bad flash on my EeePC 2G Surf was soldering in a new preprogrammed BIOS chip, they are only $20 on eBay.

Not an option for those without a steady hand though.

That's an option, but what about other computers ?

I do not see why not if one had the hardware to program memory or could find a preprogrammed chip and had the soldering skills.

I know, it's not exactly an easy fix, but if your mobo cost a lot of money and there's no other way, it'd be worth a try.

A real kludge but it worked. If you decide to go that route then I suggest you look at getting a 'SOIC' test clip instead of the wiring methodology of the author. Just $10-$20 depending on chip pinout.

If not then solder the small gauge wire, wire wrap wire 30 AWG will suffice. Make sure to keep the wire lengths short as possible to the interface. The author is living on the edge when it came to the Vcc or voltages for the chip. Preferred method would be to have a good regulated source.

I really enjoyed reading about the authors methods though it was cumbersome the desired end result was reached.

One man's junk is another man's treasure!

Why?

I can solder some SMD components and it's really not that hard.

Because its a mega pain to solder.
I find soldering regular through board components easy.
SMD was designed for robots, not humans.

The seller I bought from has other systems listed, I'm sure he could do most laptop BIOS chips. Most desktop computers have a socketed chip and there are plenty of sellers for those too.

Of course through-hole is easier, I could do that in elementary school, but SMD is not that hard. I don't have a fancy hot air station or anything, just a regular Weller dual iron temperature controlled station. If you are trying to do it with a $4 Radioshack iron, you're going to have problems, but a with good iron, a good tip and a steady hand, it isn't that hard.

For me, $20 plus 5 minutes of soldering vs $80 for a motherboard, it was no contest, especially since the laptop is only worth about $120.

My soldering equipment is not exactly up to SMD.
Its fixed temperature and the tip is not as small as i wish *sigh*

Yeah, I don't have good enough equipment either to solder that, so I'd probably try the method in my link.

I bought my station used for $30 and it has been great, it has paid for itself many times over. It isn't the latest and the greatest, it is over 10 years old. The tip I used to do that BIOS wasn't my smallest, my small pencil iron on the station has a bad tip, so I used the regular one. Having a nice iron like this will improve your through-hole work too.

This is some other SMD stuff I've done, replacing the LEDs on a Honda CBR 600rr's gauge pod to change the backlight from amber to blue:

You can see, my equipment is nothing special.

Hi,

Great price for a Weller station. What about the Fluke?
