Found something interesting re MS-DOS

I found this blog post:

http://www.os2museum.com/wp/ms-dos-oaks/

MS-DOS were supplied to OEMs with source code for IO.SYS, FORMAT.COM
and SYS.com.

It seems like with this it could be possible to make a special CBM-II
version of MS-DOS that is as compatible with PC as the stock MS-DOS 3.3
(except for defragmentation utilities and similar stuff) but with the
possibility to use more of the disks for DOS. Choose a combination of
tracks, sectors and sides that gives a total number of sectors that
line up good with the number of sectors that's on a CBM disk.

Perhaps two different formats, one that uses all of the disk except two
sectors for BAM and directory (to make it possible to read the
directory in CBM mode and realize that it's a MS-DOS disk and not just
a disk containing garbage that can be overwritten). The other format
would leave just enough space for the CBM-II PC emulator software with
BAM and directory entries on the disk, and leave the rest for MS-DOS.

(Or maybe it's already good enough as it is?)

I know that this is partially kind of taking a step in the wrong
direction when aiming for something as much PC compatible as possible,
but it seems like a good idea to have as much space as possible on each
disk.

Just a suggestion.
