Ok...here are some options for you. (I just bought this drive so I went through this)
If you're doing a fresh install, go into the BIOS and select "SCSI Boot Device" (or whatever your mobo calls it) as the secondary boot device (since you'll be booting off the CD to install Windows). On another PC (or before you reinstall) copy the files from the Maxblast CD to a floppy...there should be an "XP-something" directory (copy the whole directory), then copy something like "txt.oem" and ultra.inf (I wish I had the CD here to tell you, but you'll see the files I mean. The ones you don't need are the language files). WHen you boot off the XP CD, press F6 to specify a third party RAID driver, and insert the disk you just made. It will then see the drive and you'll be able to install to it.
If you're using it as a secondary disk, you should be able to install the Ultra133 drivers right from the Maxblast CD. Windows should then be able to see the volume in Storage Manager.
Just a word of warning...I did the first setup, and my boot time into Windows was incredibly SLOW. (Over a minute to boot). I took out the card and am running it off my ATA100 bus, and it boots in less than 20 seconds. I don't know what the difference is, but since the 133 doesn't really buy you anything, if you like a fast boot I'd stick it on the mobo. Hope this helps.
