It provides an internal 50 pin narrow bus, an internal 68 pin ultra-wide pus, and an external 68 pin ultra-wide bus. As I undertand it any 2 of the three busses may have drives attached. Mine has worked fine for me, however I haven't been able to verify ultra-wide operation under 2.2.2 (from CD) since kernels built from CD source don't seem to support the 40 Mbyte/sec rate (20 Mbyte/sec does work) I am told however that the latest 2.2.2 cvs branch (is that STABLE or RELEASE?) and the current branch both do ultra-wide transfers. --------- Christopher R.
