Hi,\n\nI have a 875P Nero series MB with 2 SATA and 2 IDE drives connected through\nthe promise controller. This PC used to boot but after CMOS was accidentally\ncleared it won't boot at all.\n\nWhilst installing XPPro I press F6 at the appropriate time to load the SATA\nand RAID drivers off the floppy, but after choosing the files It gives me an\nunexpected error (85) and If I continue I get the message drives not found.\n\nIn the BIOS no drives are found except the 2 CDROM and DVD drives. Why\nhasn't the Bios detected the drives, could it be something to do with the\nperipherals part of the BIOS where PATA, SATA and RAID etc. is configured?\n\nI admit to knowing next to nothing on this section of the BIOS.\n\nThe relevant web-sites that tell you step by step to install XP do not\nmention unexpected errors or workarounds! Perhaps there are just too many to\nmention.\n\nOne last thing, when I first switch on I get the ability to alter RAID\nsettings, Striping and mirroring etc. with the different drives actually\nrecognised!\nIs this info. kept in the BIOS?\n\nPlease help as I really am getting desperate to what should be a relatively\nsimple process.\n\nMany thanks,\nWill.
