Zenith's MS-DOS 3.30 Plus and Compaq's MS-DOS 3.31 will probably work, too. Both support partitions larger than 32 MB.Additionally to V20/V30 CPU you will need to have MS-DOS 4.01 or newer to support 100 MB medias)

You can always downgrade to 6.3. Or try to convince pcdosretro to come back to the forum and hope he still has the source
I no longer remember where to find the original source, but here's an old website that cites it.
https://comp.sys.ibm.pc.classic.narkive.com/hOYF4M6R/best-os-dos-for-a-pc-xt-round-3
The author of PC-DOS 7 was also a member here at one point under the handle pcdosretro, and he himself corroborated it
Any way to patch PCDOS to address this issue? I have GLaTICK running on my Compaq Portable with an AST MegaPlus II (running PCDOS 2000 with a V20) and was scratching my head on why it didn't quite work!
he easiest way to update I've found is to boot from one of these and use SYS to replace the IBMBIO.COM on the target device.
Aaagh! They're 1.44MB images! Remember, we're talking about XTs here.

Both my XT Turbos have 1.44 disk drives.
