My Asus P5B Deluxe-WiFi won't work any more after trying to update the bios in windows. It said it was erasing my current bios and then tried loading the new one but it failed verifying, so I restarted and no boot messages or anything!! I tried to reset it by using the CMOS jumper, move from pins 1-2 to 2-3 then switch back after 5 seconds. I tried removing the battery, recovering using a floppy and cd (took firmware named it to AMIBOOT.ROM and tried to reflash and force-reflash using CTRL+HOME) I've been reading and people have said to use a recovery cd but I don't have one. I've also read that some people had no hope and had to get a new motherboard or a new bios chip (not sure my motherboard has a switchable chip because its built in) Has anyone had experience in this kind of thing? What's the easiest solution? Please let me know if you need more info.
If you need a new bios chip, you can get them pre-flashed with whatever bios you want, look on ebay, but you'll also need a chip puller and wrist strap. Very easy job to do when you get the bits.
I heard about people doing this, but when I look up my specific board, people say it has a built-in bios chip which is soldered into the south-bridge.
Sorry, I even had one of these boards before, and never realised they didn't have a chip. It appears that recovery is possible, but risky! If you are unable to get an RMA from supplier or even Asus, then you have nothing to loose by trying the following. Hope it helps, I didn't read the whole thing, but it looks s though it should work. http://mondotech.blogspot.com/2009/05/asus-p5b-deluxe-bios-recovery-spi-flash.html
