From: mullally@sse.ie (Ronan Mullally) Subject: [Summary] More than one Extended partition Date: Wed, 28 Jul 1993 16:25:21 GMT
I really put my foot in this one :-) I was under the impression that I
could only create 2 logical partitions within each extended partition,
which I now know not to be the case - any number of logical partitions
(within reason!) can be created, along with the necessary entries in /dev.
To illustrate the point, an extract from one of the replies:

Thanks to all who replied.
