I tried to install IBM OS/2 version 1.3 on a 33 MHz Northgate Elegance
system equipped with an Adaptec AHA1542B controller, but the install
program could not detect the hard drive. OS/2 is supposed to work
with SCSI devices (recent PS/2 machines use SCSI drives), but
apparently the BIOS extensions supplied by Adaptec were not recognized
by OS/2's installation routines.
Has anyone else has had this problem and is there a work around for
it? If there is a work around, are there more problems or limitations
that I might encounter after working around this glitch? Thanks
in advance for any assistance.

Hi:
Try writting your own drivers. I wrote one for the ST01 and the ATI Wonder
+ under OS/2 1.3 EE. Just take the codes that are supplied for the old OS/2 ve
rsions (I think Adaptec has one for OS/2 1.1...) and hack it.

The new IBM Model 90 and 95 have SCSI hard disks, and according to their product information literature, OS/2 SE and EE versions 1.2 and 1.3 support these machines. Is anybody out there actually running OS/2 on a Model 90 or 95 so that this information can be verified?

We're not running on a Model 95, but we *are* running both SCSI and ESDI drives on a Model 80-A31. The SCSI and ESDI drives, along with their control- lers, are standard IBM equipment, and are on the educational pricing schedules. We run this machine for our lab's file server, running IBM LAN Server software. OS/2 EE version 1.2 ran fine on this machine, and I am happy to say that ver- sion 1.3 of the OS/2 EE software runs fine also. So, I can say that IBM's version of OS/2 supports IBM SCSI and ESDI control- lers just fine. (We have a 115-meg ESDI drive and a 320-meg SCSI drive at- tached to the machine.) The question that people would like answered, however, is whether or not IBM's version of OS/2 will support non-IBM disk drives and their related controllers. -Dennis -D. Robert Spexet II, P.O.

Now I will tell the 30 people in my department that they cannot use the server HD's anymore because OS/2 doesn't support SCSI. That also means that our 3 CD ROMS don't work anymore because OS/2 doesn't work with SCSI. Gee...I was just about to put in an order for another SCSI CD ROM and a larger SCSI HD but since you say OS/2 doesn't work with SCSI then I will not do it... well...enough with the sarcasm.

I am continually surprised whenever I see this statement: I have OS/2 1.3
running on my Northgate clone with an Adaptec 1542B SCSI host adapter with
no problems. What doesn't work, I am told, is HPFS on a SCSI; I can't tell
you from my own experience, since I haven't yet tried it.

But there is a performance panalty of course. With the PM2012A/95 EISA/SCSI controller I 'only' get 4MB/s transfer rate with the Wren Runner-2 in WD1003 emulation mode. The latest high performance EATA-mode driver at the moment is for 1.21 (OS/2), which supports bus mastering, 33MB/s transfers (EISA), etc.. Jukka

What doesn't work, I am told, is HPFS on a SCSI; I can't tell There seems to be much confusion about SCSI support under OS/2. As far as I know, OS/2 currently supports *IBM's* SCSI hardware. But SCSI host adapters are not standardized and thus each of them requires a special (different) driver for OS/2. Thus, many other SCSI adapters may not be supported under OS/2. I saw Adaptec (for 1.1) and Future Domain (don't know about version) advertizing OS/2 support for their SCSI adapters. On the other side, several SCSI adapters, such as the 1542B from Adaptec (am I right? I have read this) simulate a standard ST-506 controller on the register level for the first two SCSI drives. This allows OS/2 to run on those adapters but it can only use the first two drives (hard drives). I have not yet tested such a machine. But I cannot imagine why OS/2 1.2/1.3 should not be able to use HPFS on such controllers as it has no problems to use HPFS on real ST-506 controllers or other controllers that emulate ST-506, like IDE adapters (I use an IDE board with two drives and use HPFS). I have heard too, that Nokia Data offers their OEM version of OS/2 with driver for the Adaptec 1542A because they use this controller in their machines. I got this information directly from a Nokia Data representative here in Germany.

Although I have no hard numbers to show you all, it cer- tainly seems (in a subjective sense, anyway) that HPFS is *much* faster than FAT, especially when the server is doing write operations. We ran FAT at first, to do a speed comparison. The FAT system bogged down when there were a lot of files in any particular directory. Locating and opening those files took a lot of time to do, especially when compared to HPFS. So, at least on IBM drives and controllers, the FAT *and* HPFS file systems work just dandy.

I presume you bought both your machine and OS/2 from Northgate. I bought my machine from ALR and OS/2 from IBM. Northgate was not interested in selling me the SCSI driver for the Adaptec controller board, so I was unable to get a working scsi driver for my system. To all who respond to my comment with a "Well it works for me", please keep in mind that scsi and OS/2 go together only in very specific circumstances(i.e. where did you buy your hardware/software and what hardware do you happen to have. These circumstances are a minefield for the unwary who expect to get everything, put it together and run. To anyone with those expectations I say "Stay far far away from SCSI or suffer the consequences". -- David Feustel, 1930 Curdes Ave, Fort Wayne, IN 46805, (219) 482-9631 EMAIL: feustel@netcom.com or feustel@cvax.ipfw.indiana.edu

(Sigh) Yes, we have a LAN with two model 90's for the servers. The servers each have, in addition to the internal SCSI drives, 1G Seagate Wren VII SCSI drives externally attached.
