Microsoft Windows NT 3.1 Workstation
Released July 27, 1993
For IBM PC compatible 386/486/Pentium systems.
Windows NT 3.1 was the first of the Windows NT series. Sporting the
same face as its consumer counterpart Windows 3.1, it was completely
different under the hood. A true 32-bit native operating system,
Windows NT descended from the work Microsoft did while collaborating
with IBM on OS/2 after the great split, and bringing in former DEC
employees like Dave Cutler, bringing a VMS influence into the system.
It was followed up by Windows NT 4.0.
IMPORTANT:
Setup doesn't detect processors newer than the original Pentium, as
well as some models of 386, 486, and Pentium processors. To bypass
this, two INF files must be edited after the first stage (in text
mode) of setup is done. Change the line STF_PROCESSOR = "" ?
$(!LIBHANDLE) GetProcessor to STF_PROCESSOR = $(ProcessorID_I586) in
INITIAL.INF and SETUP.INF files in the SYSTEM32 subdirectory of the
target installation directory. If you're doing this on a 386
processor use I386, and for 486 processor use I486 instead of I586.
