    10.05.96    Shunichi Kajisa (shunk)     Support NEC PC-98

    1. Determine if autorun is running on PC-98 or regular PC/AT by:

            bNEC98 = (HIBYTE(LOWORD(GetKeyboardType(1))) == 0x0D)? TRUE : FALSE;

        Following description is from KB Q130054, and this can be applied on NT and Win95:

            If an application uses the GetKeyboardType API, it can get OEM ID by
            specifying "1" (keyboard subtype) as argument of the function. Each OEM ID
            is listed here:
             
               OEM Windows       OEM ID
               ------------------------------
               Microsoft         00H (DOS/V)
               ....
               NEC               0DH

 
    2. If autorun is running on PC-98, replace every "I386" resource with "PC98" at runtime,
       regardless that autorun is running on NT or Win95.


    Notes:
    - NEC PC-98 is available only in Japan.
    - NEC PC-98 uses x86 processor, but the underlaying hardware architecture is different.
      The PC98 files is stored under CD:\pc98 directory instead of CD:\i386.
    - There was an idea that we should detect PC-98 in SHELL32.DLL, and treat PC98 as a different
      platform, like having [AutoRun.Pc98] section in NT CD's autorun.inf. We don't do this, since
      Win95 doesn't support this, and we don't want to introduce the apps incompatibility.
      In any case, if app has any dependency on the hardware and needs to do any special things,
      the app should detect the hardware and OS. This is separate issue from Autorun.exe.
