I'll remember that one as I've never used it with non ISA cards.

Bootup should take seconds.  On a 10Mb/s  network moving 10MB should take what?

10MB = 80Mb =8 seconds at 10Mb/s (or is it nearer 10bits to a byte with network
overhead ?)

Have you got your nfsserver running?  After booting the kernel, you'll see a
message like
"doing the pivot_root"  I think this is where the NFS filesystems on the server
are mounted.  Next thing is an X-server starting on the client connecting to
your xdm on the server.

on SuSE use YAST to install an nfs-server and configure your /etc/exports to
publish your ltsp directories


the script ltsp_initialise should have altered it to add something like

## LTS-begin ##
#
# The lines between the 'LTS-begin' and the 'LTS-end' were added
# on: Sun Dec 15 18:03:05 GMT 2002 by the ltsp installation script.
# For more information, visit the ltsp homepage
# at http://www.ltsp.org
#
/opt/ltsp/i386                  192.168.20.0/255.255.255.0(ro,no_root_squash)
/var/opt/ltsp/swapfiles         192.168.20.0/255.255.255.0(rw,no_root_squash)

# The following entries need to be uncommented if you want

You can start the nfsserver

 with 

chkconfig nfsserver on

Check your firewall isn't blocking the packets.

Also  check you can resolve names of the clients on the server.  edit /etc/hosts
with the ip addresses and names of the clients.
