Hello,

Welcome to the forum ! Can you tell us which version of SCO UNIX you're dealing with here exactly ? There are big differences between OpenServer, UnixWare, and the various specific versions of both. For example, if you're talking about UnixWare 7, this particular controller appears to be handled by the SCO-provided dak host adapter driver. However, this driver may not be available on other particular versions or point releases of SCO OS's, so if you can let us know exactly what you're running, then we may be able to help further.

Hello,

Thank you for providing that additional information. Now, my own personal experience with SCO is fairly limited (I briefly worked with SCO systems in the late '90s, but even then that work was limited to replacing them with Linux boxes), but I've done a bit of digging and hopefully have found something to help you.

According to SCO's own documentation (which still more-or-less persists on the Web at SCO Knowledge Center), the driver for this controller for OpenServer 5.0.7 is called mdac. To quote directly from a KB article titled "OSR5:What drivers are provided with the OpenServer 5.0.7 media?":

The Boot-Time Loadable Drivers (BTLD) Floppies

Please Note because SCO OpenServer Release 5.0.6 and earlier systems are unable to
uncompress the drivers in the SCO OpenServer Release 5.0.7 BTLD images, you cannot
use any of these drivers on pre-Release 5.0.7 systems.

The following lists the SCSI host adapter BTLDs that are provided in the btld.img
file. (All of these BTLDs are also available on the SCO OpenServer System CD-ROM).

ad Adaptec 154x, 164x and 174x (in standard mode)
ad160 Adaptec 2916x 3916x (7892, 7899 Chip)
alad Adaptec 294x 394x 494x (785X 7860 7870 7880 7895 Chip) and SlimSCSI 1480A/B
Adapters
blad Adaptec 2940U2W 3950U2 (7890, 7891, 7897 Ultra2 Chip)
cha Compaq Fast-SCSI-2 Adapter
ciss Compaq Intelligent Storage Subsystem
clad Compaq Array Controller
iir Intel SRCMR, SRCU-31, SRCU-31L, and SRCU-32 Server RAID Controllers
mdac Mylex Disk Array Controller
slha LSI Logic/Symbios Logic/NCR MPD 53c8xx Host Adapters
wd Enhanced IDE, ATAPI Interface

So essentially they're on a floppy disc image that you can find on the OpenServer 5.0.7 CD-ROM. Now, you of course appear to be running 5.0.4 rather than 5.0.7. With any luck there's a similar driver in a similar place on your 5.0.4 installation media; if not, then it may be the case that you have to obtain and upgrade to 5.0.7 at a minimum to obtain support for this particular controller.

Hope this helps !

I have the DAC software on 1.44 floppy you boot on to setup the DAC960 Raid controller if that will help.
