I got this Gateway Dx4300 computer motherboard with a dead BIOS chip in it, that wont start at all, so I figured it must be a corrupt bios. The motherboard was kinda nice that supports Phenom II quad processors & DDR3 ram (I think) .. so I didn't want to waste it just because it had a bad bios chip.
Buy a replacement bios chip you say ? .. sure , but i dont feel like spending $25-$35 right now for a motherboard i got for free .. so I had an idea to build a simple BIOS programmer that I can build & use to save his board and possibly others in the future ..
so the bios chip was an Macronix MX25L8005 (1MB) .. and .. luckily, it sat on a socket (not soldered in) ..
After some research, I found a few DIY kits & projects along with comercial ones like the Willem, Acron, SMARTPRO ..etc , they were all expensive. Eventually I stumbled upon a design that will probably do the job, so I built the simple circuit & started experiminteng with it .. a few attempts later, I was able to reflash the chip with a new bios that saved the motherboard from the garbage man, later I decided to add some improvements to this design to make it more convenient to use in the future.
My design is based on RayeR's with slight improvements, I have added a voltage regulator to power it directly from USB port, a switch and some LED indicators ..

The finished PCB in action, just remember to erase the chip first before re-programming, it works best that way... the extra 3 pin white-connector you see is for my personal use to get +5VDC & +3.3VDC directly out (optional) .. you don't need to have that.
Software ???
There are many option out there that work with SPI based LPT port programmer .. I tested a few, SPIPGM (DOS) worked best for me .. the pic below is from a Window$ based GUI that I also tested .. and finaly, I will definately make a nice housing for this PCB and add a ZIF socket to make it more convenient to use ..
And off-course .. here's the schematic ..

What software you used? Can you included. tnx
Thx :)
yes, this was one of my old projects I've developed, thx for sharing :) .. nadergator.com
Fortunately for me,this is what I have been looking for, Thanks a lot which windows based software can I use?
Any SPI based software would work, I think I used a dos-based sw on win xp back then ;) .. NaderGator.com
