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 This ERRATA.TXT file is obviously already out of date by definition, but other copies are kept updated on the net and should be consulted as the "current errata" for your release.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: 1. http://www.FreeBSD.org/releases/ 2. ftp://ftp.FreeBSD.org/pub/FreeBSD/releases/<your-release>/ERRATA.TXT (and any sites which keep up-to-date mirrors of this location). Any changes to this file are also automatically emailed to: freebsd-current@FreeBSD.org For all FreeBSD security advisories, see: http://www.FreeBSD.org/security/ for the latest security incident information. ---- Security Advisories: 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: http://people.FreeBSD.org/~jhb/4.1R/i386/boot0 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 18.104.22.168 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 command: /sbin/md5 /path/to/downloaded/boot0 and compare with the above.
