unable to load network bootable image using etherboot

hisuresh · 11-15-2008, 09:38 PM

Hi i am new user to Linux.
I am using centOS 5.2 distribution.
I am installing diskless Linux cluster.
I am using Etherboot.
I download boot rom form http://www.rom-o-matic.net/.
I put this image in floppy disk.
i configured dhcp,tftp servers.
it seems that they are working.
the dhcp server is assigning the client with ip address and tftp downloading vmlinuz.nbi. After that i am getting the following message:

Boot from (N)etwork or (Q)uit?
Searching for server
(DHCP)....
Me: 10.0.0.2, DHCP: 10.0.0.1, TFTP: 10.0.0.1

Loading 10.0.0.1:/vmlinuz.nbi ................TFTP download complete, but
Unable to load file.
<sleep>
<abort>
Probing for pci nic ...
Probing for isa nic....
<sleep>

this message is repeating several times.
I anyone know what is the problem please help me i am eagerly waiting for replies. Thank you

Looks like you need to edit the kickstart file to point to you PXE server. Try checking as per http://www.opensourcehowto.org/how-t...a-install.html

try this link: http://etherboot.org/wiki/doc
it has troubleshooting.
As I said before it looks like you have the wrong file path set in etherboot (soon to be gPXE ) follow this link http://etherboot.org/wiki/filename_specification and you will see what I mean.

K
now it got working.
i changed the kernel.
now problem is NFS mounting file systems.
Here i am creating root device for kernel by using,

mknod /dev/nfs c 0 255
rdev /tftpboot/bzImage

But after some time i could not find nfs in dev directory. whats wrong.
Plz post if u have any idea. Thank u very much
