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:

ftp://tsx-11.mit.edu/pub/linux/sources/sbin/fdutils-4.3.src.tar.gz
In the future, the ioctl used by fdformat might be discontinued
altogether. Please use superformat (included in fdutils) instead.

Linux kernel release 1.3.xx
Linux kernel release 2.0.xx
These are the release notes for linux version 1.3. Read them carefully,
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.

to get it all put in place. Replace "XX" with the version number of the
latest kernel.
- You can also upgrade between 1.3.xx releases by patching. For a large
set of revisions, it is not worth the effort since the full set of
patches is bigger than a new kernel distribution. Instead, get the
latest full source archive and install as above. Then, get all newer
patch files, and do
- You can also upgrade between 2.0.xx releases by patching. Each
