ADoom will run diskless on 32 Megs of RAM or more if you A) Rename the wad file to something ADoom won't autodetect (such as doom.wadd), B) create a softlink named what the wad file name was (doom.wad) linking to the new name but in RAM: (ram:doom.wadd), and C) copy the renamed wad file to RAM: and start ADoom. That's how I got it to run faster on my Blizzard 1230.
