Just blew my motherboard by updating the bios via one of dell's software updates and corrupted my bios. The board doesn't have a dual bios configuration so its corrupted so I can't pull the battery or reset the CMOS.
All of my research showed that most people just pony up and replace the mobo for $200. Unwilling to give up I kept researching and found that you can turn your Raspberry Pi into a flashrom to restore your bios. http://flashrom.org/RaspberryPi http://flashrom.org/RaspberryPi
Waiting on female to female GPIO connectors to come in mail before I can hook my raspi up to the SPI sockets on my mobo and reflash the bios. Got my fingers crossed, if this works it will be a great win!
- simcop2387 13y agoIt should work. If you have serious trouble with that then there are also devices like the Bus Pirate[1] that can do the same thing (Though I have yet to do it myself). It's really neat how easy this kind of thing has become recently with all of the hobby electronics guys driving the market and opening up doors that 10-15 years ago looked bleak at the time (though that could just be my memory coloring it). I have used similar stuff to fix up routers (though haven't had to interface with the flashrom directly) and install openwrt.
- userbinator 13y agoWith BIOSes being serial flash these days, it's really easy to read/write them since all you need is something that can do programmed GPIO on a few lines at the right voltage. An Arduino, a parallel port on another PC, etc. A lot of PC repair shops in China will reflash BIOSes really cheaply too; they usually use a clothespin-like clip to attach to the chip so they can do it quickly without having to solder anything.
