- Actually, the way the two busses work is that each is electrically
- seperate, but at no time can there be more than 7 SCSI devices attached
- even with the 2 busses.

- The chip is capable of lots of neat stuff, but the SCSI Manager doesn't
- support any of them. To do this, vendors must hack the SM.
