Subject:   Patched 5.4 kernel for Compaq R3000 series
Message-ID:  <200505150505.j4F55DA7073488@m5p.com>

Symptom: You have a Compaq Presario R3000-series machine.  When you put
the 5.4 CD-ROM in and boot up, the machine powers down shortly after you
leave the beastie boot menu.

Workaround: You need a version of the patch originated by Jung-uk Kim
(http://docs.freebsd.org/cgi/mid.cgi?200407021130.58247.jkim).  But
you can't apply the patch until after you install the system, but you
can't install the system until ... (etc., etc.).  I have posted a
patched version of the kernel TEMPORARILY at:

http://www.m5p.com/freebsd/kernel-5.4-r3000.tar.bz2

(My version of the patch, attached, is slightly different from the
original version and disables the keyboard controller test under the
control of a device hint.)  Here is how you can use this patched
kernel, after logging in as root:

A. Unpack the contents of a FreeBSD CD-ROM in some temporary space.
For example, mount the CD-ROM on /cdrom and make a directory
/usr/tmp/5.4.  Then cd to /usr/tmp/5.4 and do:

(cd /cdrom, gtar cvf - .) | gtar xvfp -

B. Replace the distributed kernel with the patched kernel.

cd /usr/tmp/5.4/boot/kernel
mv kernel kernel.orig
tar xvfy kernel-5.4-r3000.tar.bz2

C. cd to /usr/tmp/5.4/boot.  Add the lines:

hint.atkbdtest.0.disabled="1"
hint.acpi.0.disabled="1"

to the end of the file loader.conf (unless you know that ACPI works
on your R3000).

D. cd to /usr/tmp/5.4 and burn a new CD-ROM with this command:

mkisofs -R -b boot/cdboot -no-emul-boot . | burncd data - fixate

E. Install with the patched CD-ROM.

Install in the usual way.  But after the base distribution has been
extracted, go to the emergency holographic shell (ALT-F4) and replace the
kernel which was just installed with the patched kernel:

cp /dist/boot/kernel/kernel /boot/kernel

You should now have a working system.  Here is my modified version
of Jung-ok Kim's patch.                        -- George Mitchell
