It's a standard Adaptec 2940AU type controller if it dies you can use a regular PCI bus controller. Which I also have.That board with the built in SCSI is interesting. it seems very convenient. I guess the downside is if it dies its not just a matter of swapping cards but then its also less internal clutter
Forgot to mention I also have a ASUS P2B-DS a dual slot 1 with the same onboard SCSI. I have ran dual PIII's 1Ghz in it and it is really fast. Missing the supports for the processors though. Also has Tualatin microcode updates. Can even provide matched pair of PIII 600's to it! Don't have the 1GHz CPU's anymore
sold them a while back.
