+Mtools and fdutils
+==================
+
+   The floppy ioctl numbering scheme has changed in 1.3.x. For
+backwards compatibility, the old numbering scheme was supported
+throughout 1.3.x. A warning will be printed in 2.0.x when the old
+numbers are used, and their use will be discontinued entirely in 2.1.x
+
+   In order to avoid trouble, you need to recompile any programs that
+emit floppy ioctls. These include mtools and fdutils. You can get
+mtools at:

+These are the release notes for linux version 2.0.  Read them carefully,
 as they tell you what this is all about, explain how to install the
 kernel, and what to do if something goes wrong. 
 
-Linux version 1.3 is a DEVELOPMENT kernel, and not intended for general 
-public use.  Different releases may have various and sometimes severe 
-bugs.  It is *strongly* recommended that you back up the previous kernel 
-before installing any new 1.3.xx release.
-
-If you need to use a proven and stable Linux kernel, please
-use 1.0.9 or 1.2.13.  All features found in the 1.3.xx releases
-will be contained in 2.0 when the code base has stabilized again.
-
-If you decide to use 1.3, it might be a good idea to follow the kernel
-channel, available as newsgroup (under linux.dev.kernel) and as mailing
-list.  To subscribe to the latter, e-mail majordomo@vger.rutgers.edu,
-and put in the body of the message "subscribe linux-kernel" or
-"subscribe linux-kernel-digest" for a daily digest of the mailing list
-(it is a high-traffic list). Note that getting subscribed or unsubscribed
-sometimes takes days or even weeks.
