FreeBSD 4.1 Errata Notes

If you read no other documentation before installing this
version of FreeBSD, you should at least by all means *READ
THE ERRATA* for this release so that you don't stumble over
problems which have already been found and fixed.  This ERRATA.TXT
file is obviously already out of date by definition, but other
copies are kept updated on the net and should be consulted as
the "current errata" for your release.  These other copies of
the errata are located at:


     (and any sites which keep up-to-date mirrors of this location).

Any changes to this file are also automatically emailed to:

For all FreeBSD security advisories, see:

Current active security advisories:	None

---- System Update Information:

The FreeBSD Boot Manager (boot0) has a bug that causes it to hang the machine
during boot with no screen output.

Fix: Boot your machine into FreeBSD either via a boot floppy or a CD-ROM, then
download a new boot0 binary from the following location:

Once you have downloaded the new binary, install it with the boot0cfg command
onto your hard disk.  For example, if you have boot0 on disk ad0, you would
run the following command:

	/usr/sbin/boot0cfg -B -b /path/to/downloaded/boot0 ad0

You may also use cvsup to update your source tree and build the new boot0
binary from source.  You will need version of
src/sys/boot/i386/boot0/boot0.s or newer.

The MD5 checksum of this file is:

	MD5 (boot0) = 8770a386dba44f0aa06b15db72c1f624

To verify the checksum of your downloaded copy, perform the following

	/sbin/md5 /path/to/downloaded/boot0

and compare with the above.
