[BProc] How do I make a beoboot kernel that will work with beoboot-cm.1.5?

[Larry B. <ba...@us...>]

I have the Clustermatic 3 CD distribution installed, and I want to use =
the beoboot-cm.1.5 package.  I downloaded the beoboot-cm.1.5 tarball, =
made an RPM, installed it, created a phase 1 boot floppy and a new phase =
2 image file.  Unfortunately, it did not work.  From Eric's release =
notes, I assume this is because the phase 1 kernel does not support =
tmpfs.  I also assume the phase 1 kernel it is using is the one that =
came with the Clustermatic CD distribution, because I can see from its =
.config file that it does not support tmpfs.

I tried using the non-smp bproc kernel from the Clustermatic 3 CD =
distribution as my phase 1 beoboot kernel.  It made it further into the =
boot process, but it failed with: "Couldn't find symbol real_mode_conf".

Next, I tried to make a new beoboot kernel with tmpfs support using the =
kernel source tree from the Clustermatic 3 CD distribution:

   # cd /usr/src
   # tar -cf - linux-2.4.19-lanl.22 | ( cd /home/baker/tmp ; tar -xf - )
   # cd /home/baker/tmp/linux-2.4.19-lanl.22
   # cp configs/kernel-2.4.19-i386-beoboot.config ./.config
   # vi .config

      Change # CONFIG_TMPFS is not set
      to     CONFIG_TMPFS=3Dy

   # make symlinks
   # make dep
   # make clean
   # make bzImage

"make bzImage" fails when compiling lib/rwsem-spinlock.c.  The errors =
are: "redefinition of `init_rwsem'" and other function names, =
".../include/asm/rwsem.h:85: `init_rwsem' previously defined here" and =
other function names, and "structure has no member named `activity'".

Given a clean Clustermatic 3 CD installation, how do I make a beoboot =
kernel that will work with beoboot-cm.1.5?
