In LTSP/K12LSTP, the client uses BOOTP/PXE to download a kernel and
an initial ram disk. The initial ram disk contains software to NFS
mount the server and to execute the LTSP software via NFS. The X
server the client runs, for example, is located on the NFS share.

PXES is self-contained, the boot image contains all of the software
needed, including the X server. NFS is not used at all (and since
the LTSP software is *only* on NFS, PXES never uses the LTSP software).

When you boot via floppy, are you using a LTSP or a PXES image?
If you are getting hotplug errors, it must be PXES since LTSP does
not include hotplug...

Could you post your /etc/dhcpd.conf? That'll help us figure out exactly
what software is running.
