I was finally able to boot the install disks from floppy and proceed with
the installation by disabling the parallel port controller ppc0 in the
visual kernel configuration.

I tried disabling all other unused devices except ppc0 (keeping only fdc0,
wdc0, wdc1, ppc0, atkbd0, and sc0 -- I also have the PCI-based fxp0 but you
can't disable that without removing the card) and the problem still existed
(even though the visual kernel configuration stated there were no
conflicts). When I disabled ppc0 it worked. I'm able to boot the system by
disabling _only_ ppc0.

After installing, I need to disable ppc0 automatically otherwise the boot
would hang with the same error as originally described (except it changed to
the boot disk instead of fd0).

To automatically disable ppc0, I did the following (mostly just documenting
this in case someone else runs into the same problem):

1. At the boot prompt, enter "boot -c".

2. At the "config>" prompt, enter "visual" to enter the visual kernel
configuration editor.

3. Disable ppc0.

4. Once the system has booted, log in as root.

5. Verify that /kernel.config contains the following lines,

     di ppc0
     q


6. Move /kernel.config to /boot/kernel.conf

     % mv /kernel.config /boot/kernel.conf

7. Create /boot/loader.rc and add the following lines verbatim.

     load /kernel
     load -t userconfig_script /boot/kernel.conf
     autoboot

8. Then reboot.

I still don't know that the original problem was (and now I can't use the
parallel port). Can this information be added to the FAQ, handbook, or
ERRATA.TXT file? 

Steps 6 and 7 are in the ERRATA.TXT file on the FTP site, but there's no
mention of a problem with ppc0.

Is there some known problem with ppc0? I can't seem to find a hardware
conflict.
