I wish I wrote the error messages down.  Something about unable to mount
03:05 or something.  I could reproduce the same error by compiling the
kernel without RamDisk support.  Then I could make it go away by only
changing the RamDisk in the kernel.

My installation process went like:
1. Do default Gnome Installation on master (27BZ-7)
2. Set network settings on master.
3. edit /etc/config.boot and add:
	pci     0x1148  0x4300  sk98lin
   so that my ethernet card will work.
4. Rebuild the beoboot image.
5. Build the boot disks.
6. Boot slave 0.
   Here I get the mounting error.
7. Recompile kernel with RamDisk support.
8. rpm -Uvh --force bproc*
9. Boot all nodes and enter in beosetup
10. Now get bproc errors (see further down)
11. download bproc tarbal.  Do make, make install, reboot.
12. Do the beofdisk -d, beofdisk -w, install kernal on /dev/hda on slaves
13. Everything seems to be working fine.

I might have forgotten a few steps.

This is the error I get when installing via RPMS:
[dvos12 at ohm-master1 dvos12]$ bpsh 0 free
bpsh: Child process exit abnormally.

When I run `make install` on the tarbal, reboot, then everything is fixed:
[dvos12 at ohm-master1 dvos12]$ bpsh 0 free
