I have just installed a new SATA 74Gb Raptor hard disk into my PC (see my sig below) and removed all the EIDE drives. So that WinXP will install the SATA drive only, with no fuss and I can install the EIDE drives back in later for reformating and what-not....of course it's all gone rather pear shaped rather than plain sailing!!! The PC POSTed fine after putting in the SATA drive, but it could not see the SATA drive (from within WinXP initial installation/drive setup). So I restarted and this time hit CRTL+F to get into the Auto Setup Fastbuild Config Utility within the BIOS before WinXP CD fires up and tries to install again. OK, this Utility could see the new SATA hard disk....so I set it up for "performance" (stripe, apparently) even though there is only one disk. Mobo manual says it can be built with either 1 or 2 drives. The only other option is "security" (mirrored). Rebooted and allowed WinXP to try to install again....and it still could not see the drive. So, maybe I'm thinking I should have used the F6 option to install FastTrak 376 drivers. The mobo has a built in Promise RAID controler and both SATA sockets on the mobo are RAID enabled. So options come up and I hit "S", but then when I pop in the floppy disk WinXP required it could not find the "txtsetup.oem" file on the floppy....bugger!!! Nothing again!!! I may have copied the files wrong, but I did exactly as the manual said "...copy the files inside root Promise from CD". Which looks like this within the the Promse folder of the mobo CD (I've included sub folders too): \FastTrak376 > \winxp > \98-me > \win2000 > \nt-4 \MBFastTrak133 > \winxp > \98-me > \win2000 > \nt-4 So there are two folders under "Promise", "FastTrak376" and "MBFastTrak133". Both have a "txtsetup.oem" file inside plus the subfolders (winxp, nt-4, etc) containing their relivant files, exactly the same as is on the floppy copy I made. But something is not working! I have no idea what may be wrong or what I may have done wrong. To say that the Chaintech mobo manual is crap is an understatement....nothing about installing to a SATA drive, just stuff about RAID and FastTrak376. The main BIOS (not the Fastbuild Config Utility) is pretty bare bones, there is absolutely nothing within that appears to have anything to do with SATA controllers. All PC connections are fine. Any help would be most welcome....before I make this Raptor hard disk as exstinct as the dinosaur its named after.
