Good thing I've got more than one machine. I tried to use NLite to create a CD with the RAID driver slipstreamed but that didn't work out, so I had to hook up a floppy. I guess I'll have to manually merge the driver - lots of good stuff at www.msfn.org.
I've had to do a repair install and it's looking good so far.
But why does it happen when I've just finished Far Cry?
