    MS-DOS with an expanded memory handler can only address up to 64mb.

    Maybe EMS, but XMS third-party drivers are available (along with matching RAMdisk drivers) for memory up to 2GB.

    IF all he is going to do is game the best he'll ever use is 16mb.

    If you've got more, why not use it for something? I've got 1GB RAMdrives on a couple of Win98 boxes here.

    Ditto, Works great with my USB flash drives, I also use 'LoadSys' to load / unload the driver when needed.

    Some games may not work properly. I have a Pentium 200 system where I pulled 64MB out so I just have 16MB left. That solved a lot of stability / not running issues for older games.

    Got a Pentium 120 CPU in the mail yesterday. Will probably put that in. Some games run a bit too fast in a Pentium 200.

    FreeDOS can handle up to ~4 GB with memory expanders IIRC. I've installed it on machines with 512 MB+ and I recall it seeing all of it as expanded/extended memory, but that was a long time ago.

    I'd question the need for such a ridiculous amount of RAM on a DOS machine unless you were writing your own OS or something to take advantage of it.

    Yeah, I remember running into that problem back when I had Windows 98SE as my main rig in the late 90s. Some DOS games like Duke3D had a bug where if you had over a certain amount of RAM, the RAM check would overflow and it would refuse to install. DOS4GW also seemed to have a lot of problems with lots of memory installed and applications that used it frequently crashed.

    FreeDOS is a bloated sack of open source trash. I never consider or suggest it as an alternative.

    ^^ FreeDOS works great and I run it on everything. There's no way I'd bother with MS-DOS unless I needed to run an old version (3.3, etc.) on something ancient. YMMV.

    MS-DOS 6.22 works great.
