I can only piece a bit of it together. Apparently there are logical
partitions involved, and the EPBR is supposed to hint at that. And
the EPBRs form a linked list. That accounts for there being more partitions
than there is room for primary partitions in the MBR.

The only bit that doesn't seem reasonable to a casual glance, is these lines.

Almost like they overlap. I guess the 05 is the actual EPBR (declaration
of logical), and the line below it is the partition inside ? Maybe
that's OK then.

I see what you mean; the partition label (2nd) list shows the above,
while the partition detail (1st) list shows:
4192965 1 00 522 0 1 05 782 254 63 8385930 4192965
8385930 0 00 522 1 1 06 782 254 63 8385993 4192902 .
I note that the EPBR in the first list has the same start and end
values, so i consider that as a marker for logical drive E(WORK).
The E:WORK starts at 4192965 and the FEVEL starts at 8385930; both
are logical drives "inside" the extended section.
I see this EPBR "marker" right before each logical drive.
Type 05hex is EPBR and type 06hex is FAT16B; FDISK shows the primary
partition with the extended partition right before I:MASTER, exactly
what i wanted.
Then it prompts if you want to see the logical drives; if yes then
WORK and DEVEL are shown.

The apparent overlap is from what i am calling a "marker" (first
line) for the extended partition.

So it all seems OK.
*
However, GhostPE calls them "noname" for copying; i will not talk
about Acronis; it is so bad i am going to ask for my money back and
trash the files and CD i had made (trash for the trash).
