Well, if it where not for the Quantum Grand Prix I would offer the loan of a NCR 810 card, but I know that to be a problem :-(. > > I just tried running a kernel without bounce buffers, without an ed0 driver, > > and with MAXMEM set to 16384.

Agreed, I have never seen it recover from this once it happens. > Now I'll go out on a limb and guess: our Buslogic support is broken.

I would, but the only other PCI card I have won't play with the Grand Prix drive that he has (or so I've been told, haven't been able to test it out here since I don't have any Grand Prix drives). > In spite of what Rodney said earlier, I like Buslogic because they > have been extremely helpful to me in the past, and so the help they > gave me cancels the four hour phone wait Rodney had, and FreeBSD > customers should give them another chance and let's not put them > on our "Don't buy this stuff" list (It wasn't that long ago that > I regularly saw "buy Buslogic" postings). I use to boast that Bus Logic was one of the best products around to get, and would still if not only myself, but David and Jordan both spent similiar N hour sessions tryings to get to there technical support folks. It is a very clear indication that when tech support gets that far back logged (I left no less than 5 messages, and still 30 days later have not had a return call!!!) that they have a *real* product problem. There tech support use to be *excelent*, I have even said so in many mail messages. It is sad to see this has changed for the worse :-(. I will not be pursuaded to change my stance on Bus Logic due to past record. There current record is horrible, and that is enough for me to pursuade people to seek alternatives, realize I sell these products, and customers of mine would not be very happy if I sold them something I know to have compatibility problems, and know that tech support is lacking for. > Is anyone in a position to get a known working PCI SCSI board to > sef? I would, but don't have an alternative that would work in his setup, well, wait, I have a aha2940 here, sef, you want to try that out? I could send it out UPS Red on monday, you would have it Tuesday. Wait, that won't work, he is trying to install 2.0R which does not have proper support for the aha2940 :-(, arghh...!!! > This is a FreeBSD support challenge and I'd like to see us rise to > it. I am trying, but can't do much when the system has products in it that have known problems that I have tried to resolve as best I can myself (why do you think I wasted 4 hours long distance on hold to Bus Logic.) I would rather go after the Quantum/NCR problem at this point in the game than I would go after BusLogic any further. -- Rod Grimes rgrimes@gndrsh.aac.dev.com Accurate Automation Company Custom computers for FreeBSD
