Argh! Concerning the Ciprico Rimfire 1500, I forgot a very important feature -- it supports Scatter-write/Gather-read for all you folks with a paged memory scheme. You don't need to use a bounce buffer for this guy -- just give him the list of starting addresses and lengths for the physical memory fragments of the buffer, and it will go to it. For Unix users, this is only important for the raw (character) device interface, but if you are using your SCSI bus for tape, this is very important indeed -- things like tar and dd run much better if you don't have to bounce the data through a contiguous memory buffer, and who wants to wasted 32-126K of memory, anyway? -- John Lind, Starfire Consulting Services E-mail: john@starfire.MN.ORG USnail: PO Box 13001, Mpls MN 55414
