hi !
Windows 7 runs on a P2 with 266MHz CPU, 96MB RAM & 4Mb graphic card !
i have done 3 tests: 2 successful...
1. 128 MB RAM
2. 96 MB ram
take a look at the screenshots...
on my third test with 64 MB i got some errormessages about "insufficient memory", then it rebooted...
i also have a P1 with 166Mhz CPU & 1MB Graphic card, without the powersupply-unit, as i have used it for some test on another PC.
if i can find the Powersupply-unit, i´m going to test the P1 tomorrow...
