Has anyone managed to get more than 2 installations of Windows NT 4.0 on a single system? A few years ago I got the idea of making a multiboot Server/Terminal Server/Workstation setup, but although the first two installed OK I could never get the third to work.

I'd assume you have three drives, one bootable, and install the bootloader on the first one to boot the other three. Even if they absolutely refuse to install with each other, just swap the drives out. Once they are all installed, just set the bootloader up to boot to each installation.

The drives on this system can't be swapped out for complicated RAID related reasons.

Ms-Dos 6.22, Linux, Os/2 Warp 3.0 and Win95.

A multiboot of every major MS-DOS release is also something I've thought of, but never tried.

oooo idea.

Get a whole whackton of floppy controllers and have every major MS-DOS release

on floppy

all at once

with like 10-12 floppy drives

idc, make it work.

You are not really thinking about running them at once? In that case you can not use multiboot.
For that you need to run some sort of Virtualization, eighter on a host operating system or use a server such as VM-Server.
I might have read and understood this wrong.

EDIT:
When I heard about multiboot around 1992/93, I thought that they were talking Virtualization.
People told me that this could never be done, and I was introduced to it that way.

I mean have all of the major DOS versions installed onto floppies, that are installed on the computer. Make it a 0 HDD system.

Next up: Floppy diskette RAID 0

I did it many years ago for my brother in law, he needed several versions of windows to test his own software (he has a little software company). So i offered him to build a testsystem, just one system for every MS operating system.

I made a system with 3.11, 95, 98, 98se, millenium, windows2000 and windows xp.

I used several harddisks, a lot of partitions and a bootloader. It was a pain but i managed it. The problem was something with the loader i used (don't remember which it was).
I believe there was a cap for 4/5 systems max in the menu, so i had to watch the sequence of installation so i could use the bootmenu from 2000 and XP as submenu's.

this sounds painful.

now people have massive blade servers hypervising it all.

Ahhh... Now it makes sence to me, what you wish to do.
Well... I think it will be really hard to cramp even MS-Dos 5.0 onto one Floppy.
You will be missing a lot of tools and programs, as there is not enough space.

Take MS-Dos 6.22 installation disks. As far as I remember, the file names are
more or less just renamed. So a complete 6.22 installation is more than 2 x 1.44 mb
And since a pc can only have A and B drives (2 drives) I think you need to
be really inventive in this case...

Is this understood correctly?

Yea you got it.

There do exist 2.88MB floppies.

And if you have multiple controllers, they won't be directly bootable, but you can use a bootloader.

One of my PCs has 98, Xp and Linux.
98 has a sub menu for Win98 or Dos 7.

Another Pc has Linux, XP and Win7.
Main Boot menu let you choose between Linux, Windows, PlopBootManager or Memtest.
Chooing Windows gives you the option to Boot Win7 or WinXP.
WinXP has a Submenu for 1,2 or all 4 Cores enabled or XP-Repair-console.

Third Pc has a Menue between Dos 6.22 with Win3.11 or Windows 95.
