The problem is the aic support. Currently, the 3.3 - REALEASE (and any 3.x ) does not support Adaptec AHA 1520B (AIC driver) under the new CAM scsi susbsystem. Here is an explanation why: ----- Original Message ----- From: John Reynolds~ To: Richard Cotrina Sent: Monday, October 18, 1999 6:00 PM Subject: RE: Adaptec AHA 1520 Support > > [ On Monday, October 18, Richard Cotrina wrote: ] > > > > #uname -r > > 3.3 - RELEASE > > > > You mean that the only solution is to change my SCSI board :( ? > > I used it without problems in RH Linux 6.0, even in SCO Openserver 5. > > Why FreeBSD does not have support for this card ? > I don't remember all the technical details why. The people who wrote the new CAM scsi subsystem that went into production at 3.0 either did not have time or felt that it was too difficult-for-the-benefit to support this old hardware with CAM. From what I understand it is a really really old scsi chipset which uses PIO mode. With the old scsi system the driver "worked" but didn't work well due to lack of documentation on its interface from Adaptec. I can vouch for this. I had a 1520 hooked to a CD rom in 2.x and when I plugged a new scsi drive on it I kept getting panics--it was really not very good for anything other than what those guys deemed "light weight" devices such as CD-roms and scanners. The new CAM scsi system is N times superior to the old system and one of the best scsi implementations in the free world. So, given the benefits, I'd say they have to outweigh the downers for a few people (including myself at one time) who have 1520's.... Doesn't help your sitation, but that's as much of it as I can remember. I'm sure if you search -current or -hackers looking for 1520 you'd find the whole trail about this (about 1.5 years ago). Or, if you ask "really nice" on -scsi, maybe one of the developers will give you a technical reason (a much better one than I could) about why it was too difficult to support or their justification. -Jr -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- = | John Reynolds CEG, CCE, Next Generation Flows, HLA | | Intel Corporation MS: CH6-210 Phone: 480-554-9092 pgr: 868-6512 | | jreynold@sedona.ch.intel.com http://www-aec.ch.intel.com/~jreynold/ | > =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- = To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
