To be able to recompile our Linux kernel for our IBM Blade Center, here are a listing of the necessary prerequisites:

• Have the sources installed and available under /usr/src/linux-2.4.9-e.35
• The bcm5700 driver located at /usr/src/redhat (provided by IBM)
• Our standard configuration kernel file, i.e. .config provided as an attached file

Adapt our custom kernel configuration file and the top Makefile:

# cd /usr/src/linux-2.4.9-e.35   /* Go the top sources directory. */
# make mrproper                  /* Make sure you have no stale .o files and
                                    dependencies lying around. */
# sum .config                    /* Verify our customized kernel configuration
64319    16                         file. */
# make oldmenu                   /* Default all questions based on the contents
                                    of the existing .config file. */
# cp Makefile Makefile.orig      /* Check the top Makefile for further
                                    site-dependent configuration. */
# diff -u Makefile.orig Makefile

Verify the files are present in /boot!

Verify that all these new stuffs are OK, then reinstall the network driver using the provided RPM package:

# shutdown -ry now
/*
 * If all is ok, then access the machine through the IBM Management Module
 * Console (MMC).
 */
# cd /usr/src/redhat
# rpm bb SPECS/bcm5700.spec
# rpm ivh --force RPMS/i386/bcm5700-8.1.11-1.i386.rpm
# grep bcm5700 /etc/modules.conf
alias eth0 bcm5700
alias eth1 bcm5700
# modprobe bcm5700

Test if the network is running OK for now, then reboot.
