If your BMI server is using Red Hat, verify that the following software is installed on your BMI server:
Python
Python-xml
TFTP server
If you are going to provision Solaris systems, you also need nfs-utils, configured to export /tftpboot/pxelinux.cfg as read only (ro)
Work Station 3.0 does not have tftp-server; use the RPM from the Advanced Server distribution.
