Re: Diskless Notebook

["Richard C Ferri" <rcferri@us.ibm.com>]

Heinrich,
     In my network boot kernel (which I run on diskless workstations, but
haven't tried laptops) I have 4 options I had to turn on myself in the
kernel:

NFS root on (CONFIG_ROOT_NFS)
ext2 filesystem (CONFIG_EXT2_FS)
BOOTP and RARP support (???)
Enable option to get IP address from the original bootp  ( I think this is
CONFIG_IP_PNP_BOOTP)

Do you have all of these enabled? Now, my diskette has only the ethernet
device driver on it, not the entire kernel.  I serve my kernel over the
network directly.  My kernel is also monolithic, meaning it has no loadable
modules (all kernel options are yes or no, none are set to module)  I got
my info from one of the original etherboot web pages, long ago...

Regards...

Hi,

I am trying to run diskless Linux on a Toshiba notebook.
I compiled a 2.4.0 kernel with
     - IP: kernel level autoconfiguration
     - PCMCIA support
     - a driver for my PCMCIA network card
     - Root file system on nfs

I copied the kernel to a floppy (w/o LILO) and bootet the laptop.
The network card was recognized and initialized, but too late! The
kernel had already tried IP autoconfig before and found no devices. So
it all ended with

     "Root-NFS: No NFS server available, giving up"

Is there any way i can get this to work? I have not tried supplying
Server IP on the kernel command line; i do want to use bootp-config.

TIA
