> That's certainly one thing I don't miss about old DOS gaming, having specific boot disks around with the proper config.sys/autoexec.bat magic to make ornery games work -- base RAM, HMA, EMS, XMS etc..

I don't remember in which MS DOS version it was introduced (perhaps 5.0?), but that was the normal way to go after that.
