Normally, when I get RAID/Sata drivers, it gives you them in a zip archive w/ a bunch of unneeded files. you may have put on the wrong files. Also Kurtislan, use a usb floppy if you have one.
Idk if that is any help.
and Yesterday, A PC REPAIR SHOP SHOULD SO (MAKE THAT SO, SO, SO!) be able to find a RAID driver. I could probably find it in a few mins on driverguide or even the mfg. site! Then just put the correct files onto floppy.
