You may want to consider this if you are buying a card. I think the 14F is an ISA, and the 34F is the VLB. I own a 34F. The card is supported by FreeBSD (included in the BT generic kernel I think). I currently have a 245Meg Maxtor, a Bernoulli 150 (removable) and a 1 GIG IBM drive on it. I have also used it with a NEC 2X CDROM and a Sanyo 2X CDROM. I have even used it to share a SCSI bus with my Amiga 3000. (2 hosts, 4 or 5 drives total at that time). The card has given me no problems. I can't say much about the speed of it though. When I upgraded from FreeBSD 1.1 to 1.1.5, the speed seemed to have fallen, yet it should have gone up because of improvements in the OS. I haven't tracked this problem down yet. Running a benchmark program (forgot the name), I seem to get 1.75 Megs/s on read and write to a 100Meg File on the IBM drive. The other drives currently have other OS's on them. There were sample benchmarks included with the benchmark software, and the above 1.75 blew them all away, but they were old benchmarks on differnt machines (Suns, etc). I would like some sort of comparison base to judge the speed against. BTW, the rest of the hardware is a 486-66 with a ATI GUP VL and 16 megs of RAM. I have also used this same hardware for DOS/Windows and OS/2. No problems with any of them. --- Ken Robinson NRNS Incorporated e-mail: robinson@nrnsinc.on.ca I am under the opinion that my opinions are my own opinions, but that is just my opinion.
