Re: bug ?: Disappearing DOS partitions (fwd)

I'm resending this message.  It was returned to me as undeliverable, and 
I never got a copy of it as a member of the mailing list, so I'm 
supposing it never made it.  Sorry to any of those who have already 
received this message.  Thanks.

	Thanks for offering to help.  Sorry it took me so long to reply.  
I'm sending you the information you asked for, but first I think I should 
reexplain my problem.  I don't I did a very good job of it in my first post.

	After having added partitions to my hard disk using Linux fdisk, 
and successfully installing Linux.  I was able to boot to DOS and see, 
consult, write to, and otherwise use two logical disks on the extended 
partition.  I could come back to Linux and see all my DOS disks (one a 
primary partition and two logical disks).  Then one day, booting to DOS, 
the logical DOS drives were no longer there.  Couldn't see 'em, couldn't 
use 'em, autoexec.bat couldn't find 'em.  If I booted back to Linux, 
however, there they are.  I can mount them and do anything one would 
expect to do with a mounted file system.  But not under DOS.  As you will 
see in the following partition table reports, DOS seems to have lumped 
the two logical disks and the Linux logical partitions into one big 
extended non-DOS partition.

	Here goes, the partition table as reported by Linux fdisk, cfdisk 
(Linux), and DOS fdisk.

	Hope this helps you to help me get back my logical DOS drives.  
Thanks again.
