Program: SAVE32.COM is a TSR included in the Windows95 distribution which
     preserves the contents of 32-bit registers across invocations of
     all of the hardware interrupt handlers (which, for some older BIOSes
     and TSRs, do not properly preserve the high words of the 32-bit
     registers)
