Hmm, let's see. Adaptec 1540[B/C] Adaptec 1542[B/C] Adaptec 1740[B/C] Adaptec 1742[B/C] Bustek 742a Ultrastor 14F (and I think the 24F as well recently) And many other drives emulate the Adaptec's, so I'd say that Adaptec SCSI is *the* SCSI standard, and as such anything that emulates it will get you by. >In the IDE world there are Quantum, Conner, >Maxtor, and a host of others, delivering a commodity.

Nope, there have been problems with some VLB IDE controllers, but those are usually hardware problems. The deal with IDE, is that it is a standard as well (similar to Adaptec) >I expected to have problems with my serial and parallel ports, since >my IDE disks, floppies, two serial and one parallel port, are all >run out of one ASIC!

If you want workstation performance, you need to spend a little bit on the hardware. If you don't care, and want to run cheaply and as a single user, then go cheap. However, "If you want to run a Real-Man's Operating System", you really need "a Real-Man's hardware" to do it. :-) Nate -- nate@bsd.coe.montana.edu | In the middle of it ........ again. nate@cs.montana.edu | Running/supporting of many freely available work #: (406) 994-4836 | Operating Systems for [34]86 machines. home #: (406) 586-0579 | (based on Net/2, name changes all the time :-)
