MAME had a completely broken warez version of Windows NT 3.1, that was replaced with a known-good unmodified copy. Language variants of Windows NT 3.1 were also added (I don't have the non-English copies of future versions, can't do those at this time). Advanced Server is added to the list.

Windows NT 3.5 was added new.

Windows NT 3.51's CD-ROM image was not the original copy, and likewise updated to a known-good unmodified copy. Server was added to the list.

Windows NT 4.0 was added new, all known-good copies and editions of such.

The image that was listed here is a hacked-up warez version from 2003
that doesn't function properly (won't install on most computers NT 3.1
should be able to install on).

In its stead, this is a list of pristine images direct out of
Microsoft, no modifications have been made to them, and NT 3.1's
(admittedly limited) full hardware compatibility is supported.

All language variants are included here, too.

Taking from the BeOS example, floppy images that are intimately tied
to the CD-ROM are listed in the same entry in ibm5170_cdrom.xml, since
they are only useful in booting a computer in order to install from
CD-ROM (which requires a compatible SCSI controller and SCSI CD-ROM
drive).  Installing from MS-DOS is always another possibility.
“Workstation” wasn't the name of the client SKU yet
The existing floppy-edition images checked out with official sources,
but renamed to be consistent with Microsoft's own naming of the
operating system.
Changed the CD-ROM hash of Workstation to a known-good copy from an
original CD, added Server, added the full floppy disk edition of
Workstation.

It started to bother me that Windows 2000 was alone without these kind of additions and fixups (ignoring the non-NT Windowses, at least for now... those are an even bigger mess to unravel). Being that Windows 2000 is NT 5.0, it seems to fit the theme of the pull request. I swear it's my last change here. :-)

I'd like to note also that NT 3.1, 3.5, 3.51, and 4.0 are all multi-architecture disc images. All of them run on IA-32 (ibm5170_cdrom here) and MIPS (mmr4000le); NT 3.1 build 528 and all the rest also support Alpha (afaik no MAME driver supports it); and PowerPC was added in 3.51 (likewise no MAME driver supporting it). Maybe the images should be duplicated to other software lists. The floppy images are exclusive to IA-32, but the other architectures have firmware that allow direct CD installation.

Windows 2000 is the only single-architecture (IA-32) version here. Actually it's the only version of NT ever that got released only for a single architecture. :)

This is the first version that shipped without a floppy-only edition,
the only floppy disks are to assist in booting the installer on
computers that don't support floppy boot.  It is likewise the first
version to support El Torito booting.
The Windows 2000 image existing in prior commits was _slightly_ off an
official build.  Official builds use the AutoCRC feature of cdimage to
make sure images have a CRC32 hash of 0xffffffff, accomplished by
editing a few bytes in extraneous sectors of the ISO-9660 file system
that are not user visible.  The prior image did not have these bytes,
albeit everything else was a match.

Listed here are a complete set of Windows 2000 Professional, Server,
Advanced Server in all service pack levels and RTM.  The "Select"
licensing disc was used for all of them; this version was released for
volume licensing and does not require a product key to be entered.

Also included are the MUI language packs and standalone service pack
1-4 installers, sourced from official CD-ROMs also.
These are all sourced from Microsoft distributed CDs, containing
support for all architectures and an autorun file.
