Sorted now.
I had a proper read through of the manual that came with the motherboard and although it said to make a floppy for the VIA RAID, it worked fine with just the one disk.
The computer is FAST though, I can't get over the difference between this and my old Athlon XP 3200 with Maxtor 200GB IDE drive.
Actually getting the driver onto a floppy was a nightmare though, I had to boot up my 3200, then remote desktop into the 1800 to create the floppy disk because that's the only one with a floppy drive anymore.
Then I had to swap monitors over to the FX53, connect the floppy drive (oh the shame!

) and install it as theblueraja said.
It didn't accept the WinXP version though so I used the Win2000 drivers and it seems fine, the disk could have been corrupted though (re: not accepting XP drivers) because the only one I could find was a 10 year old OS/2 install disk.
Seems to be working though, but I can't quite get over the fact that the disk seems to format in 5 seconds or less?
I know these drives are fast as hell but is this right?
