XENIX
  Late one night, I was meditating on a Model 90 Announcement Letter without the benefit of Jolt Cola (the horror! the horror!). For a few moments, my dulled senses reported SCO XENIX System V  2.3.2 as XENIX - Warrior Princess... No. Not that lucky.

My intent for this page is to find significant files needed to install and maintain SCO XENIX 2.3.4 on Micro Channel (MC) systems. I do not intend to install XENIX of any revision, if one of you-all heroes or heroines wandt to, go for it!

SCO XENIX System V 386, versions 2.3.2 and 2.3.4 will run on ST506, ESDI, and SCSI based 386 systems. 2.3.2 needs a few SLS to fully support MCA, while 2.3.4 is far better. However, BOTH need SLS to be applied for full support.

XENIX 2.3.4q All hail Michal Necasek! File on WinWorldPC
   NOTE: The 'q' was a revision letter. The releases were not always clearly labeled but the revision letters were inside the installation archives. FYI, except for the boot floppies the XENIX install disks are TAR archives.

The PS, MC, GT stuff was kind of marketing, but it generally identified what hardware the particular XENIX release was meant for. I do not know why they went from "PS" to "MC", but I guess it was because XENIX MC actually supported a couple of non-IBM Microchannel systems.

  IBM Microchannel EFS Release 2.0.0 for SCO XENIX 2.3.4MC (NOT for 2.3.4GT) includes 3 disks, a replacement N1, a microcode update  disk and a LINK kit update disk.  This EFS replaces the IBM Model 57 EFS for SCO XENIX 2.3.4MC. EFS124 on the BBS. If a 2.88 MB floppy drive will be used for installation, no other EFS/SLS is required - the floppy drive will be used as a 1.44 MB density.
         After installing, if they want to be able to use it in full 2.88 MB mode, they will need to install the 2.88 MB Floppy EFS for Xenix Microchannel, or QFS117 in the US.

E  = Support Level Supplement xnx232b may be necessary to install XENIX 2.3.2 on machines  built with a Seagate ESDI drive model number st177i. Also, the 80 MB ESDI drive on the PS/2 Model 55SX requires xnx232b, and the 80 and 160 MB ESDI drives on the PS/2 Model 70 requires xnx232b.

E1 = Early Model 70 machines require xnx106 to install. Note that replacing a 60MB drive in this machine will require an upgrade to 2.3.2 and the Supplement xnx232.

F  = This machine comes with a 2.88 MB floppy diskette drive, and the     operating systems indicated will not install on it. There is a      supplement planned to provide support for the 2.88 MB floppy under XENIX 2.3.4 MC

X  = An Extended Functionality Supplement is necessary to install XENIX 2.3.4 on the IBM PS/2 Model 57SX.

P  = Will work with Support Level Supplement xnx155b and writeup on the
Model P70 in this database.

Q  = Will work with Support Level Supplement xnx155b and the writeup on the Model 75 in this database.

S  = SCSI hard disk is an option for this system. In order to install XENIX on a SCSI based PS/2 you must have the IBM SCSI Extensions to      SCO XENIX, available through Telesales.

S1 = SCSI hard disk is an option for this system. In order to install XENIX on a SCSI based PS/2 you must obtain XENIX 2.3.2 and the IBM SCSI  Extensions to SCO XENIX, available through Telesales, or use XENIX 2.3.4.
    
There is no Support for the IBM SCSI Host Adapters in XENIX 2.3.3.
