I'm in the process of installing SCO Unix onto a 10MB partition. 

- HDINIT starts out by saying it will initialize the HD - however having not used it before, I want to make sure it will give me the option to choose my ESProfile image and not just automatically format the internal Widget drive (which has LOS) with all my other software loaded and a dual workspace. 

Can someone please confirm?

Also any other roadblocks I'm about to hit as I seek to install this on a 10MB image?

Expectations are that you are installing to the 'built-in' disk, and the paths reflect as much. To install against an external ESProFile on the parallel port while keeping your Widget connected is an exercise in understanding /dev/p0a vs p1/p2/p3. It's possible, but risky. I'd recommend disconnecting the widget data cable just to be safe.

You might also have some difficulty booting the kernel from the parallel port disk, as the boot command might need to change.

Thanks - this goes back to me trying to start an image off of Port 1 on the Parallel card.  SCO image was not working, as I get the following from the image that was on the SD card:
Boot:
"Enter Return"
pf(0,0)xenix
not a directory
xenix not found

My assumption is it's not seeing the drive on the parallel card - I'd assume from the boot: there is a way to see what devices can be mounted or no?  Not knowing Xenix - what's the format of the PF(0,0) command - x,y?

I don't recall offhand, but it might be drive number, partition number.

If your card is in Slot 1, try pf(1,0)xenix or pf(2,0)xenix. This will require some digging thru the manual and testing.

Solved:
For those with the parallel card in Slot 2 (Top port) - the command to start is pf(5,0)xenix

I think I was wrong on that format. For Uniplus, it's not partition number but block offset. Example: w(0,2501)unix is drive 0 (builtin) with offset 2501 to find the file named 'unix'.

Xenix is likely similar.
