Didn't make a backup, did you? That's OK, neither do I. ^_^U |

First, see if the motherboard can be saved. If the BIOS is fried, |
| 20 |
usually the boot block will kick in. Drop in a floppy drive |
| 21 |
(optionally, an ISA video card as well; strangely, an AGP video card |
| 22 |
worked with my LANParty's BIOS). Google your BIOS maker's name and |
| 23 |
the words "boot block" for specific directions on what to put on a |
| 24 |
floppy disk. Then, start your computer with the floppy in the A: |
| 25 |
drive, and if the boot block survived (it's usually not updated when |
| 26 |
flashing the BIOS), it'll automatically reflash itself from the |
| 27 |
floppy and then restart, loading the new BIOS and hopefully saving |
| 28 |
your ASCII. :-) |

Hopefully your RAID BIOS (and CMOS) is a separate chip from the |
| 31 |
system BIOS that shouldn't have been affected by the above ordeal. |
| 32 |
If it isn't working, then read on. |

If you remember your stripe size, then you should be able to plug |
| 35 |
your drives into any ICH5R-based motherboard and get your data back. |
| 36 |
Theoretically, you could plug your drives into any RAID whose BIOS |
| 37 |
does not write to the disks when creating an array and then recreate |
| 38 |
the array in the BIOS with the same stripe size. I don't know if |
| 39 |
software RAID can rebuild your array, but that seems like your best |
| 40 |
bet, lest you have a friend with a lot of SATA RAID controllers (s) |
| 41 |
he's willing to lend out. |
| 42 |
|
| 43 |
If all else fails and your data is priceless, grab a couple grand and |
| 44 |
look into professional data recovery, because unless you can find a |
| 45 |
super-geek, that will probably be your best bet. |
