I am interested in the availability of dos drivers to handle a SCSI hard disk. The standard AT&T issue of MS-DOS does not contain a SCSI driver. It may be that a SCSI driver does not exist for DOS. Anyway, I would appreciate any info on such a driver, if it exists. Thanks. Don Klett dsk@arch3.att.com (908)949-2283

By the way some SCSI controllers use RLL encoding. ------------------------ James F. Van Valkenburg a.k.a. "van" AT&T Attmail: !jfv jfv@cbnewsk.att.com Atlanta, GA.

I think NCR's version of MSDOS includes SCSI drivers for their machines, although it may actually be in the NCR bios. -- David Feustel, 1930 Curdes Ave, Fort Wayne, IN 46805, (219) 482-9631 EMAIL: feustel@netcom.com or feustel@cvax.ipfw.indiana.edu

The good controllers that will allow peak SCSI performance (WD FAAST, Adaptec, etc), but cost more. Many of these don't need drivers for vanilla stuff (Only disks, no more than 2 disks, etc). With the right driver, they can support up to 7 devices (disks, tapes, CDroms, etc). SCSI controllers implement NO encoding at all. All that is done in the drive itself, and yes, most SCSI drives implement RLL, or ZBR technology.
