Can't mount ad0s2

[Brian Astill]

Slice 2 on ad0 is a DOS extended partition.
I have tried to mount this partition (or to be more accurate the logical 
partition inside that extended partition) using every combination of -t 
xxx and /dev/ad0sn I could think of that might work - no dice. [:-(]  
Yes I HAVE checked that the appropriate /dev/ files exist.
Yes I HAVE used fdisk to verify that the partition exists, is recognised 
and SHOULD be mountable. 
I have even used Partition Magic 7 to confirm the existance of the 
extended partition and the logical partition it encloses.
There is obviously something I HAVEN'T done [:-)]

How do I mount that recalcitrant partition, please?

FWIW, here is PM7's listing.  The only "odd" thing is the EPBR (Extended 
Partition Boot Record?), which fdisk didn't see - and which I don't 
understand [:-)]
