"PC DOS 7
PC DOS 7 was released in April 1995 and was the last release of DOS
before IBM software development (other than the development IBM
ViaVoice) moved to Austin. The REXX programming language was added, as
well as support for a new floppy disk format, XDF, which extended a
standard 1.44 MB floppy disk to 1.86 MB. SuperStor disk compression
technology was replaced with Stac Electronics' STACKER. An algebraic
command line calculator and a utility program to load device drivers
from the command line were added. PC DOS 7 also included many
optimizations to increase performance and reduce memory usage.[16]
PC DOS 2000
The most recent retail release was PC DOS 2000 – released from Austin in
1998 – which found its niche in the embedded software market and
elsewhere. PC DOS 2000 is a slipstream of 7.0 with Y2K and other fixes
applied. To applications, PC DOS 2000 reports itself as "IBM PC DOS
7.00, revision 1", in contrast to the original PC DOS 7, which reported
itself as "IBM PC DOS 7.00, revision 0".[nb 1]
Hitachi used PC DOS 2000 in their legacy Drive Fitness Test (4.15) and
Hitachi Feature Tool (2.15) until 2009.[17] ThinkPad products had a copy
of the latest version of PC DOS in their Rescue and Recovery partition.[18]
PC DOS 7.1
PC DOS 7.1 added support for Logical Block Addressing (LBA) and FAT32 partitions.[nb 1] Various builds from 1999 up to 2003 were not released
in retail, but used in products such as the IBM ServerGuide Scripting Toolkit.[19] A build of this version of DOS appeared in Norton Ghost
from Symantec.[20] Version 7.1 indicates support for FAT32 also in
MS-DOS.[16]
Most builds of this version of DOS are limited to the kernel files
IBMBIO.COM, IBMDOS.COM, and COMMAND.COM. The updated programs FDISK32
and FORMAT32 allow one to prepare FAT32 disks. Additional utilities are
taken from PC DOS 2000, where needed. "

There might even be a patch for 7.0 to bring it up to 7.1 if you know
where to look.
