>While you're at it, can you let me know how well BSD supports 1. Adaptec >2842 VL-Bus adapters (I had a hell of a time getting it running with Linux, >finally did, your hardware files list the 2842 but say it was just >translated from Linux-- I wrote the aic7xxx based support for FreeBSD, and it currently supports the 274x, 284x, and sorta the 294x cards. THe 274x and 284x support is rock solid (I own one of each card), and is a far cry from a driver simply "translated" from Linux. The driver offers improved performance by supporting tagged-queing, two commands per non-tagged queing device, better syncronous and wide negotiation protocols, and uses DMA transfers for sending its commands to the board. The kernel level driver is a total re-write. What is shared is the sequencer code (the program that is run by the scsi controller's little RISC chip). My ideas, and modifications to both my kernel driver and the sequencer code have been given back to the Linux community, but there has been slow movement to incorperate the code. Only one developer has been putting any time into it, and he has been busy lately -- and he's working on switching to FreeBSD ;-). >not sure which translation, not sure it will work- >do you know who might know or who I should contact?) If it doesn't work, drop me a line. I would suggest trying the latest snapshot boot disk on your machine to see how it goes: ftp.cdrom.com://pub/FreeBSD/2.0-950210-SNAP/floppies/boot.flp.gz >2.
