The old PC-MOS was released under the GNU GPL this Summer. From Wikipedia:

PC-MOS/386 was a multi-user, computer multitasking operating system produced by The Software Link (TSL), announced at COMDEX in November 1986 for February 1987 release.[1] PC-MOS/386, a successor to PC-MOS, can run many MS-DOS software titles on the host machine or a terminal connected to it. Unlike MS-DOS, PC-MOS/386 is optimized for the Intel 80386 processor; however early versions will run on any x86 computer.

The GitHub project includes a 1.44MB disk image for the latest version that will work under VirtualBox, but does not include older versions of the operating system from before it required an 80386+. The system won't work properly if you set a modern date at the boot up prompt.

RE[3]: PC-MOS 386 vs FreeDOS

Why bother with 10MBit? I've got a 133MHz retro-gaming PC which dual-boots DOS622/Win311 and Win98SE and it's got packet drivers for a 100MBit PCI NIC.

In fact, I'd have used one of my Intel PRO 1000 cards just for the built-in PXE boot support, but the motherboard seems to be PCI 1.0 and can't boot with my old Voodoo 3 3000 PCI installed either.

This page has a surprisingly comprehensive collection of DOS packet drivers on offer. (Especially when you consider that some, like the Realtek RTL8139, are chips used across wide swathes of cards.)

I paired it with a DHCP client, NTP client, and SSH2DOS from FreeDOS to automate keeping the clock in sync and avoid having to re-burn a DVD-RW every time I want to copy over a new piece of nostalgic shareware.

Throw in some other stuff offered with FreeDOS, like UIDE, SHSUCDX, 4DOS, ANSIPLUS, and so on, and you can get a surprisingly Linux-like DOS experience while still having a ton of conventional memory free.

(In my case, 617K with over 30K upper memory still free for future TSRs with Windows 3.11 for Workgroups's bloated networking helpers permanently resident and without having to resort to QEMM or anything else proprietary beyond DOS and Win3.11 themselves.)

P.S. UIDE+SHSUCDX instead of OAKCDROM+MSCDEX gives you support for DVD-sized ISO9660 filesystems.
