He's talking about the CDU distro of DOS 7.1 which works great

Sorry, what you mean "CDU distro" ?

The CD image you have with DOS 7.1 was put together by an outfit called the "chinese dos union"

I don't know anything about them, but the DOS works great

freedos, DOS 7.1, and DOS mode in windows 9x all have fat 32 support. You can make the partitions as big as 2TB - at least theoretically.

DOS is fat 16. The 16bit address space is 2gb. One way to get around that is to make a bunch of partitions each 2gb in size. I think DOS 6.22 can address as many as four of them, or rather as much as 8 total GBs no matter how you divide them up.

🙂 May I have the patch for MS-DOS 5.0?

Sure, no problem. 🙂

Browsing a harddisk under DOS without using BIOS routines (INT13H)

You'll need a copy of English MS-DOS 5.0, though.

And you need a BIOS that does not limit int13h (it needs to hold 12-Bit cylinder numbers. Virtual PC 2004/2007 is suitable).
See Re: Unable to see more than 2GB of my HDD

MS-DOS 5.0A may not work with the utilities, because they predated it.
Manual patching with a hex editor should also work with DOS5.0A and DOS 6.x, though.
