Hello again everyone ... here's what I've got.
I started from scratch, reinstalled RedHat 7.3 on the Master node and all the clients. Our (hopefully soon-to-be) cluster consists of one single processor box for the Master node and seven dual-processor boxes for the compute nodes. I'm running the smp kernel on the Master node to avoid compatibility issues. There's one important note, however:
I had to compile some drivers provided by Intel to get support for the on-board network cards. The drivers were installed in the usual manner with an "insmod" command. Everything seemed to work fine. The MAC collection worked without error as did the creation of the autoinstall boot floppy.
When I reboot the nodes with the boot floppy everything seems to proceed normally. I can watch the network traffic come over from the Master node and all the files appear to be installed. However, when I remove the boot floppy and reboot the node, I get the following messages: (Does anyone know a way to scroll back and read the lines that have scrolled passed? I've tried the Ctrl-PageUp and Ctrl-B, but neither seems to work.)
<long list of unresolved symbol errors regarding mptscsi.o>

What's curious to me about this is that the same SCSI controller is in each of the machines, however the problem seems to be that the drivers for the SCSI controller are never loaded upon reboot after network installation.
Should I create my network install image on one of the client nodes and port this to the Master node? If so, what set of RPMs do I need to include in my client installation? Also, has anyone done this before?
Thanks for all of your help.
Tony
