Plan 9 would run well. Netbsd would be solid, particularly if you don't care about X. Openstep if you could find a CD. Minix. That's an amazing amount of RAM for that era, and OS/2 4.0 would probably run well on it, with no need to hunt for graphics drivers. Get Turbo C or Turbo Pascal for DOS, Word for windows, solid multitasking. BeOS/intel won't run - that needed pentium arch or above. BeOS would fly on an old pentium thinkpad with that much RAM though. Network stack is patchy, but the media API remains impressive.
