Processor Check
The setup doesn't detect Pentium II processors and above, as well as some models of 386, 486, and Pentium processors, to bypass this after the TXT setup boot to a boot disk and edit the references to  to   in the   and the   files in the System32 directory of Windows. If you're doing this on a 386 processor use I386, and for 486 processor use I486 instead of I586.
