If you have the CD, you do have the drivers, but you must put them on the floppy a certain way, which the directions do not show. I have built 2 servers with this board and I had the same problem when I built the first one. I don't remember the exact spot, but go to the folder on the CD that has the Promise 20276 controller drivers. There you will see about 7 files (don't remember the exact numbers) and the folders for the appropriate operating systems. Copy those 7 files and the folder, for the appropriate OS, onto a floppy. Then you start installing XP, press "F6" at the beginning so it will ask you for RAID drivers later. When it does, put in the floppy. It will see the 7 files and give a choice of 4 drivers to install. Choose the correct one (for some reason, I think it will be the 3rd choice, but don't hold me to it). Then whichever file on the floppy has the info, it will tell XP to go to the folder and get the correct driver. This will work. I posted at this same forum several months ago.
Good luck.
