Interesting !!!
Do you still have list of hardware you used?
Thanks

For what I understand, on this industrial machine,  you have three PCs with OS/2 Warp 4, with network connection (ethernet), and 8 serial ports on each machine and these 8 serial ports are connected to the PCs with ISA cards.

I think it will be hard to VBox to emulate the 8 COM serial ports.

Backup everything. Clone the hard drives of each three machines.  (Possible you already did that).

It will be interesting to know why you want to have OS/2 virtualized there over Windows. Is there some functionality that you don't know how to use on OS/2, like using USB flash drives to extract files or VNC for remote control? Or is it that you are missing the OS/2 installer CDs? or is it that OS/2 is different to install?

Possible solutions with bare metal (real hardware) are:

1) OS/2 Warp 4.52. Since it seems you didn't upgrade any of the PCs to newer maiboards (you have that old ISA cards that you need for the 8 serial ports).  You can install OS/2 Warp 4.52 from the CD-ROM, get USB support (maybe for a flash drive), and copy the required software for this machine from the clones Warp 4.

OS/2 Warp 4.52 will save you some time with all the fixpacks for Warp 4.

2) Buy ArcaOS and it will save you also too much trouble with the OS/2 Warp installation process and it will install more actual tools and drivers (network). Since it is the same OS/2 kernel is almost sure that every driver and software will run. To install ArcaOS you need a DVD drive, or the capacity to boot from the USB port.

It would be very awesome if you can share the config.sys file (upload it as config.txt) too see if there is any special driver or specific thing for that machine we can point out.

I would love to be in Italy to check out that machine !!!! ;D

I’m trying to virtualized OS/2 because I have many old office PCs for free from our IT service and for me should be free this way...
But for shure I can buy new hardware and make a new bare metal 😉.
We don’t have installation Cd because in past we bought HD already configured for our tools when ee need to replace it.
How can I export CONFIG.SYS fron the virtual machine?
I have access only to VM now...

Regards

Daniele:
I done it !!!

Here the CONFIG file...

Thanks

Hi Daniele,

The Config.sys shows that the original OS/2 was just a standard install of the early Warp 4, including voice type and setup for a US keyboard.  The only strange thing is that it is setup to boot and run from the D: partition which indicates it might have been a dual boot setup for some reason.

Now you say you van get 'retired' computers from the IT department.  If those computers were running Win 7 then they will run OS/2 without problems.  Depending on how you have the disk image of OS/2 that you built the virtual disk image from you might be able to copy that image to the hard disk of one of the computers and it could run without problems other than changing drive letters in config.sys.  It is also possible to 'find' an ISO* of Warp  4 on the net, which might make things easier for you.

Let us know what sort of hardware you have available and the what form you have the master disk image then we can, hopefully, point you in the right direction.

The only real problem for you is going to be the cost of 8 port com add in cards - they are not cheap, the last ones we got were almost 200 euro each for PCIe ones.

EDIT to clean up typos.


Something else I just noted, there doesn't appear to be anything to run more than the normal 2 com ports, not even com3 and com4.  Are these controlled by the equipment program?

The only thing that's required is that you MUST use 3com network cards. The rest you are asking is because of OS/2. You'll save a lot by going to ArcaOS.

The 3Com network card requirement is interesting. Most people who think they know NetBIOS don't really know that much about atomic message transfer. It's in the IBM help, though. They only say that implementation is up to the network card manufacturer.

I think a simulation of the 3com card might work. But if the VM simulates something else, you can stop using that VM.
