[Beowulf] Diskless booting help:

[Bertrand Russell]

Dear Beowulf members,

I am trying to cluster up 4PCs of SUN hardware (Opteron processor) running
on CentOS-5. I am trying to  do diskless booting. I have configured one
machine as the Head node (with OS and  other programs) with DHCP and  its
running TFTP-server.  I don't have EPROM writer and  planned to use ISOLINUX
CD-ROM boot.  I have made the  bootable CD-ROM with the following files,

 boot.cat, initrd.img, vmlinuz (from CD#1 fo CentOS-5),
isolinux.bin(syslinux directory-downloaded form its official site),
and
pxelinux.cfg (copied from centos wiki).

But when I boot the client I am getting the following error message,

"kernel panic - not syncing: VFS: Unable to mount root fs on unknown block
(9,2).

I could able to guess, this is due to the kernel could not able to mount the
root file system which is not in the CD-ROM. But I want the root file system
along with other directories to be mounted form the head node. Could anyone
guide me to solve this?
