  1. I found a trick. After install, Boot to DOS, Type edit,
    Press ALT+F, Highlight C:\, WINNT or WINNT 35 (if you have win nt 3.5 installed), Press I for INITAL.INF
    and erase “” ? $(!LIBHANDLE) GetProcessor and change to $(ProcessorID_I586)
    Then press ALT+F again and press enter for save.
    Then press ALT+F again and Press S for SETUP.INF and do the same.
    On SETUP.INF, Do the same for INITAL.INF and Erase “” ? $(!LIBHANDLE) GetProcessor and change to $(ProcessorID_I586)
    Then press ALT+F again and press enter again for save.
    Then press ALT+F again to exit and remove floppy and Press CLRT+ALT+DEL.
    Windows will now load and not say Windows cannot install on this processor, but ask you for your name and company.

    Yes, this method works, but is a lot more labor intensive and must be redone every time NT is reinstalled. And it is a lot harder to use if there is no DOS partition (e.g. installing NT on a clean disk).
