I have a slightly related one... At that time I was nothing but a child, so my main interest outside "how does $THIS work" was to play computer games. I had a 386 @20MHz with something like 40MB HDD. I wanted to play this Sherlock Holmes game my dad bought for my birthday. Mind you, at that time paying for a game was a big effort for my family, so this would only happen once per year (if lucky). The problem? The game, once installed, was like 39MB or something crazy like that! There was this tool called doublespace or drivespace (can't remember the exact name, I believe both existed) that could increase your total disk space by doing some magic (actually compression, but mostly magic for barely a child). Problem solved, right? Not quite. Now I had a second problem: This tool loaded a driver, otherwise you couldn't access your data in the disk, and with this driver I could not hit the memory requirements for this specific game (which also required to load the mouse driver!). All in all, I could only play this game by deleting everything on the HDD and even trimming down c:\dos :) then installing the game. I believe some time later you could load the doublespace/drivespace driver on to the extended memory, as well as the mouse driver; plus the RAM started getting cheaper and I got a whooping 2MB expansion (so I had 4MB in total) and could play and use the computer for other... games. As someone else mentioned, you ended up with several boot options depending on the task you wanted to do. Most of the times I wouldn't even load the CD-Rom drivers (that's actually with a 486 I got a few years later) or the mouse drivers. Those were the times...
