Xenix IBM PC v1.0 Exploration

Setting up our VM

If you want to download this version, please check it out on WinWorld. This is apparently only for the IBM PC AT, which uses a 80286. Let's first set up a VM for this, I'll be using 86Box.

I created a virtual machine with the following (stuff that I didn't mention were simply left blank):

Setting type	Configuration
Machine	Machine: [80286] IBM AT CPU type: Intel 80286, 8MHz Memory: 640KB FPU: 287 Time synchronization: Disabled
Display	Display: [ISA] Hercules
Storage controllers	HD controller: [ISA16] PC/AT IDE Controller FD controller: Internal controller
Hard disks	Hard drive: IDE (0:0) drive, 615 cylinders, 4 heads, 17 sectors (20MB), with speed [1989] 3500 RPM
Floppy disks	Floppy drive(s): One 5.25" 1.2MB drive (A:), one 5.25" 360K drive (B:)

Using this configuration, try starting up the VM -- without any floppy disks in the drive, or anything like that. You might get a 161. It mentions to run SETUP.

How do you run SETUP, you may ask? IBM provided a diskette which would boot into special software that could configure your IBM AT. Luckily, people have archived this diskette -- it's available on [WinWorld https://winworldpc.com/product/ibm-pc-diagnostics/at-1x]. Go ahead and download 1.01.

Then, insert the diskette. Simply continue where it said to run SETUP. It may ask you if you have finished connecting the battery. It'll throw a 0151. Press the Enter key a few times (there might be another way to bypass this error, but this is all I know). If you skip the time and date, it'll ask you to confirm -- press N and type the following:

For time, just use the current time.

For date, the current date, but replace the current year with 1985.
