Acessing an extended FAT16 partition with Dos / Fat fsys

I’m having trouble getting a FAT16 partition mounted using Dosfsys or
Fatfsys. I can’t find the appropriate syntax to specify the extended
partition and neither utility automatically detects that partion.

My hard drive has WinXP first, QNX 4, QNX 6 as primary partitions (all
bootable) then an extended partition with the FAT16 partition as the first
logical drive. XP partition is listed as type 23, QNX 4 type 77, QNX 6
type 79, and the extended as type 15

Thanks

Do you have a /dev/hdxxxx entry for the different elements of the
extended partition?

Can you post the output from:

ls /dev/hd*

The contents of my /dev directory are:

cd0 con1 con10 con2 con3 con4 con5 con6 con7 con8 con9 fd0 hd0
hd0t15 hd0t23 hd0t77 hd0t79 kbd mouse mousein null par1 ptyp0
ptyp1 ptyp2 ptyp3 ser1 shmem ttyp0 ttyp1 ttyp2 ttyp3

I don’t see the different elements of the extended partition.

Which means I don’t think you’re going to be able to handle it.

(Which is, unfortunately, what I had kind of expected.)

You first need to get the extended partitions enumerated (appear in /dev).

My hard drive has WinXP first, QNX 4, QNX 6 as primary partitions (all
bootable) then an extended partition with the FAT16 partition as the first
logical drive. XP partition is listed as type 23, QNX 4 type 77, QNX 6
type 79, and the extended as type 15

Early versions of QNX4 mount (pre-2000-ish) did not know that a t15 was
another t5-like extended container, so won’t enumerate them from a
“mount -p”; you’ll need to get a newer mount (or QNX4 upgrade) …
