  You were really running up against DOS memory limits in the 90s, so there were all sorts of tricks to make use of some of the memory range above 640K. There was also the expanded memory spec which allowed memory from an expansion card to be basically paged into the usual memory range. So people ended up having a bunch of config files that they booted into depending upon what they were doing.

    QEMM was a must-have to keep conventional memory as free as possible. Also digging around for low-RAM-usage mouse drivers, etc helped a lot. Even then you'd run into headaches with things like Ultima 7's JEMM memory manager that insisted you not have EMM386/QEMM running. To say that managing a DOS install was somewhat painful is an understatement.

    That was right around the era where computers started having more memory than DOS could "use" and so things like LOADHIGH became so important; memory below 640K was precious especially as TSRs became common.

  I remember I learnt most of this stuff from a neighbor, he took an "informatics" course that taught him all that wizard stuff.
