Intel Unix System V 2.x

Intel Unix System V was a rather uncommon Unix variant developed and distributed by Intel, for IBM PC compatible hardware. It was considered "plain vanilla" compared to other distributions, adding little beyond AT&T's codebase.

@jonirob How do you do this in 86Box?

Revolution

@helloisthispizzahut These are my disks, here's how I did it.

86Box v3.0

Machine Type: i386DX/i486
Machine: Award 486 Clone
CPU Type: Intel i486SX
CPU Speed: 25
FPU: 487SX
Memory: 16MB
Video: Video 7 VGA 1024i (HT208)
HD Controller: Internal
FD Controller: Internal
Hard Disk: 1023 Cylinder, 15 Head, 17 Sector, 127MB IDE Drive on Channel 0:0
A Drive: 5.25" 1.2M
B Drive: 3.5" 1.44M

Be sure to go into the machine's BIOS and specify the floppy and hard disk sizes.

Forget exactly which boot disk to go with. Try the ST-506 one first.

@Revolution What if the ST-506 one does not work?

@helloisthispizzahut These boot floppies provided are for various SCSI hard disk controllers.
What you can do is use a machine in 86box that supports SCSI.

@Missileboi What machine does support SCSI?

Then how do I run setup?

Laugh all you want, but this fother mucker is FIFTY-EIGHT DISKS. Thank god we no longer need to wait on grinding physical drives; but even so this is still a lot of disks to swap out. I've been at this for like 3 hours and I'm just now getting past the device drivers and into the fmli (development?) packages.

Pack a lunch, and maybe dinner too.

Apart from that? Revolution's config recommendation for 86Box seems solid, though I've set it up as a 486DX4/100 not an SX.

It is possible to get some Intel Unix packages such as TCP/IP, debugger, compiler on stock AT&T SysV.

I used UltralISO to load the disk01of02 boot file to make an ISO and put it on the virtual machine, only Booting Unxi System appears

Working SCSI setup on 86Box...

System:
Any 386/486 I have tested works (enable dynarec)
RAM:
16MB works fine
Sound card:
None
Input:
P/S2 Mouse
Network:
No NIC (haven't got to that part yet though I'm sure its doable)
Storage Controller:
HD Controller: None
SCSI Controller 1: Adaptec AHA-154xCF
SCSI Settings:
Address: 0x330
IRQ: 11
DMA: 5
BIOS Address: DC00H
FDC: None
Hard Disk: 518mb (1054C 16H 63S)
Floppy: 1.2mb times 2

Then boot from Disk 1 labelled Adaptec SCSI

Profit

Continued from below...

Also forgot to mention, SCSI host adapter must be SCSI ID 7 and LUN 0, first disk must be SCSI ID 0 and second disk (if you want) must be SCSI ID 1. After boot press CTRL+A to open the SCSI config and check the host transfer speed is at 5Mbps (anything else will NOT work). If a second fixed disk is present then Unix will automatically use it as a /home partition.

@Missileboi Yes but there really is no need. At the description says, Intel Sys V was stock AT&T Unix, the only difference is the stuff you want so you might as well just run Intel Unix. Also I just found out, this build contains a script that seems to want to install Xenix in some sort of compatibility mode. Haven't actually tested it yet but yeah, if you run 'cat /etc/xinstall' you'll see the script.
