17 Didn't make a backup, did you? That's OK, neither do I. ^_^U
19 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. :-)
30 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.
34 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.
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.
