We are having problems installing an Adaptec 1542B SCSI controller on '386 AT box running SCO Xenix 2.3.1. We're trying to run it with a SCSI 700Mb 8000 series Maxtor HD, a SCSI tape drive, an MFM controler with a two hard drives attached (one not installed in Phoenix BIOS CMOS), and assorted other cards and periphs (VGA, 16 and 32 bit RAM, serial/paralel, mutli-port serial, no floppies). The Adaptec tries to find target 0 or something and fails (we've tried it with both and either of the tape, and the 700M HD on the bus). We got no documentation with the Adaptec, but we had a FAX of some sort of instalation card. Our worse problem is however is that we've just found that SCO's SCSI driver is just a stub. Does SCO or Adaptec have a real SCSI driver? Any help would be appreciated, we would like to get the new HD and tape up and running as soon as possible.

First, if you want to boot off the Maxtor then you MUST tell the bios that there are NO drives attached. Second, the Maxtor must be set to LUN 0, and the tape to LUN 1. The maxtor is shipped with an ID of six, which has to be changed to 0. Find jumpers JP35, JP36, JP37, and remove all jumpers on them. Then make sure that the tape drive is jumpered to an ID of 1. If it is a Wangtek drive the select jumpers are on the end of the drive. You shouldn't have any trouble after this. JB -- Jonathan Bayer Intelligent Software Products, Inc.

First, the only XENIX that supports the 154x adapter is version 2.3.2GT from SCO. 2.3.1 does not support the 154x. Second. You mentioned that the adapter failed to find target 0 at boot time. You should have the Maxtor drive set to target 0. I think it is set to target 4 by default. Reference the Maxtor docs for this. The tape drive should be set to target ID 2 or above. In all cases you will have to know the target ID's of both to install them under 2.3.2GT.
