First - don't bump your posts. You should read the forum rules on the main forum page. I did it once and was brought up on it.
Second - you could have the BIOS chip replaced. It would be simple enough on a pc build - but with this being a laptop - I'm not so sure how easy it would be. I doubt you could do it yourself - it might need to be taken in.
EDIT : Sorry my answer was so quick - I should add that it is unlikely you will be able to recover the laptop without a new BIOS chip. Also, this laptop is dis-continued. Generally if you had to replace the chip - you would contact the manufacturer and ask for a chip for your model. It would cost from £6 - £10. You may still be able to do this - but you would need your local computer shop to install it. I don't know how much that would be.
Other options would be to see if a vendor has your motherboard in stock. I did find this place but they don't stock it anymore: (http://www.aliexpress.com/fm-store/901590/210758681-448161123/E500-MS-16371-GM965-motherboard-for-LG.html) Again you'd need someone professional to install it.
Your software options are limited : If you were still able to access the BIOS it would be possible to upload the original version from a backup you should have made, or perhaps you could stick the original BIOS from the manufacturer on a USB, plug it in, then reboot - it might pick it up and replace the bad flash, I know that some boards do that, so it's worth a try.
Other than that - I'd remove your hard-drives and pull the data onto another computer, so you can at least save that.
Anyway - for future reference there are ways that you can test a flash before applying it. Preferably you should make a copy of the original before you do - and also you should check that your board has a fail-safe for a bad flash. Detecting a USB drive with a legitimate BIOS on it would be one way your board could do that.
