AFAICT, all that Sun's doing here is addings their "SUNxxG" to the vendor string so their tools can quickly identify and categorize their disks. I'm using a <FUJITSU MAJ3182M SUN18G 0804> at scbus0 target 0 lun 0 (pass0,da0) (also SCA, but sitting behind a Tekram 53c895 40 MHz LVD bus) here, and it works just great. > If we suppose that SUN guys didn't break SCSI too much here (??), > the problem may be due to your SCA-to-SCSI2 tinking machines not > connecting and/or terminating all signals as needed for WIDE SCSI. Since i was the guy advising him to ask here, i'm now already familiar with Frank's setup. ;-) He originally used a plain 8-bit configuration, his "SCA-to-SCSI2" should rather read as "SCA to 8-bit 50-pin" adapter. So there's no wide negotiation involved at all. Certainly those adapters don't terminate anything, but the disks should never enter wide mode anyway. Following my advise he changed the old configuration from using the CD-ROM's internal (passive) termination to an active plug-in terminator, which didn't help. This Dawicontrol is 8-bit only btw., despite of using an 53c875. -- cheers, J"org .-.-. --... ...-- -.. .
