Not only do I remember using DOS, I've forgotten what I knew...
My son got hold of Master of Orion I, one of the truly great computer strategy games ever. Unfortunately, I cant get it running for him. We kept an old system for playing old games (we especially like X-Com, the possibly the greatest game of all time), and we have Win95 as OS. When trying to run the game, there's insufficient conventional memory by about 13kb. I checked mem/c, and have DOS resident high; I've tried varying the PIF memory properties for the shortcut without success. I've also tried editing the autoexec and config files for the shortcut, but to be honest I'm just fumbling around there after not ahveing thought DOS for so long.
I've forgotten how to unload resident programs already in memeory, other than rebooting.
Any tips or web references would be appreciated...
