Some Germans have done their best (and are probably still trying) to make Windows XP run on minimalistic hardware. Records right now are a Pentium at 20MHz with 32MB RAM, alternatively a Pentium at 24MHz with 18MB RAM. Read all about it here: http://winhistory.de/more/386/xpmini_eng.htm Cheers Olle
It was interesting... ... to read how they underclocked the Pentium Overdrive simply by removing the CPU fan. (The fan is powered through the CPU, and without it the clock multiplier is automatically dropped from the standard 2.5 to 1.0.) Cheers Olle
Not very long, in comparison... A friend of mine used to run Windows NT4 on his 486 with limited RAM. The typical starting procedure was to 1) power it up. 2) take a coffee brake. 3) come back some 20 minutes later to watch the last few minutes of the startup sequence. No need to hurry there...
