As far as I can tell, the OpenBSD fdisk allows this, and there may be
other tools that do.
Since BeOS is my home base I started out creating four primary,
extended partitions of type 05 using the BeOS DriveSetup tool. This
tool however does not itself know how to create logical (sub-
)partitions. I tried Win98's fdisk and GNU/Linux 'parted' without luck,
and finally OpenBSD's fdisk.
OpenBSD fdisk had no complaints about the 4 extended partitions, and
let me edit 4 (logical) partitions within each of them. I didn't
actually go through with creating all 16 of them, but as far as I could
see OpenBSD fdisk is designed to allow exactly this. The 17 /dev/wd1X
characters (4x4+c) do seem like a perfect fit, FWIW.
In OpenBSD fdisk you 'select' an extended partition to enter it, and
when you're done editing you 'quit' from there to go back to the top
MBR. I didn't try nesting any deeper, but it may be supported. To what
extent the OpenBSD loader and kernel support nested 05s is another
question.
