I'm thinking about purchasing a Seagate ST-296N and I would like to know what a good SCSI controller would be. I am running an Everex 386/16 and would like this to be compatible with SCO Xenix and AT+T Unix. I would also like the ability to add an SCSI tape drive in the future and perhaps another SCSI hard drive as well (2 hard drives AND a tape drive). Can anyone give me any pointers here? -- Jesse W.

SCO XENIX 2.3GT supports the Adaptec AHA-1540A/1542A. Tape support as well. I don't know about AT&T or what they support.

The SCO Sys V/386 support of the Adaptek 1540 is pleasantly clean... I now have 3 drives in my system (a Rose Hill '386/20), 2 of which are ST-506, the other is SCSI. The SCSI drive is a Rodime 1140 (I think...) and the filesystem transfer rates (for Acer file system) seem to be around 300k/sec. Almost as good as the DECStation 2100 I use at work. Impressive, on the whole... OBTW: Does anybody know of some good SCSI tape drives, preferably less than $800, > 100MB capacity?

They have a 150MB capacity, can read QIC-24, QIC-120 and QIC-150 and can write QIC-120 and QIC-150. We pay around $650 when we buy in 1-2 quantity. We've had fairly good luck with them (no dead drives or people cussing out Archive engineers and/or their mothers). We've bought around 15 of them so far so on the whole I'd say our experience has been a 8^) one. Sorry if I ramble a bit but our software won't post unless there's more new news than old news. -- ------------------------------------------------------------------------- Dave Lyons - ...!sun!mcrware!davely | On Second though let's not go to My employer laughs at my opinions. | Camelot...

Jesse, I just posted a rather long article (72 lines) on how happy I am with an Adaptec AHA1542 SCSI controller. If you would like more information, or have questions, call me at Centel (703) 758-7000 or email to me at uunet\!grebyn\!macom1\!Larry. I just can't say enough good things about this controller. -- Larry Taborek ..!uunet!grebyn!macom1!larry Centel Federal Systems larry@macom1.UUCP 11400 Commerce Park Drive Reston, VA 22091-1506 My views do not reflect those of Centel 703-758-7000

The only downside being that AT&T nor INTEL are delivering a UNIX that can
use the SCSI controller, Adaptec 1542A or otherwise. It is, in my opinion,
a serious deficiency in their product offerings.

Keith Henson I don't think this is an answer to the original question. In order to be able to install on a SCSI drive with a particular controller, the appropriate driver needs to be in the UNIX on the install floppy. Although I haven't tried to do it, you can probably install first on an "AT" style drive (ESDI/ST506), then build a kernel that can mount a SCSI drive, then move everything over to the SCSI drive. There is some magic necessary to build a bootable SCSI drive, and I don't think you'll find this proceedure documented anywhere. In particular, you need to change the file /etc/conf/cf.d/sassign to have the major number of your SCSI disk driver instead of Interactive's number before building the kernel you install on the SCSI disk. By the way, is there anyone else that is upset at how both Interactive and SCO each have an undocumented kludge that pulls all there disk drivers under a single "psuedo-driver" so that no one else can reasonably write a driver compatible with it? Does anyone at Interactive want to defend this kludge? Gerry Gleason

The AT&T 6386E/33 (made by Intel) has an internal SCSI as the boot device. The other models use ESDI for the the boot device but can add SCSI for secondary devices. I quote: "AT&T 6386 WGS computers enhanced with SCSI support the suite of AT&T 3B2 SCSI peripherals." Sounds encouraging to me (but then I'm not manufacturing 3B2's....).

There is an installscript supplyed that makes a bootable floppy. In order to make a bootable floppy you need an up and running system. There should be no extra drivers included, otherwise the unix will bee to large for the floppy drive. You must also change the name "scsiprim" to something shorter due to a bug in "/etc/conf/bin/idmaster". "idmaster" is a program that returns the next free major number. It fails to recognise any device name thats 8 characters long although a device name can be up to 8 characters. If you don't do this the next driver you install will get the same major number as "scsiprim" and everything bails out. The above is for Bell/Intel 386 5.3.2. -- Jan Herder, MYAB Sweden | Phone: +46 31 18 75 12 Internet: herder@myab.se | Fax: +46 31 18 28 42 UUCP: uunet!sunic!chalmers!myab!herder | Address: Dr. Forseliusg 21 ARPA: herder%myab.se@uunet.uu.net | 413 26 Gothenburg
