How would you expect me to try a Tekram controller in an SBus-only Sun? :-) As i said, i've at least seen it work on an U5/U10, though i can remember that some OBP upgrade was needed due to some bug. My first test was one of the first of those U10 machines, and we supplied a SCSI controller to a customer so he could connect his tape drive. Thus booting off the card wasn't a requirement, and i only tried it out ouf curiosity. Now i remember again the bug, that old firmware wasn't really able to boot off a CD-ROM, although probe-scsi-all could see all the attached drives. Later on i tried it again on an U5, where it worked flawlessly as described. In particular for machines like the AXi that have an onboard Symbios Logic, i don't see why a plugged-in Symbios Logic card shouldn't work: the onboard controller could only boot using the supplied OBP anyway, so there's no reason why a plugged-in card should not work. One thing though is that OBP (and Solaris, for that matter) only support a small subset of the Symbios Logic chips, compared to our sym driver. The 53c875 belongs to it (and the '876 is just two '875s), IMHO the 53c895, and probably one of the newer chips. In particular, the '810s are IMHO completely unsupported. -- J"org Wunsch Unix support engineer joerg_wunsch@interface-systems.de http://www.interface-systems.de/~j/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-sparc" in the body of the message
