That's certainly a possibility.

Here's a recap (typed in by hand - there may be errors):
sis900_probe: MAC 00:2A:43:AE:30:94 at vendor 0X0400
sis900_probe: vendor :0X1039 Device 0X0900
sis900_probe: RTL 8201 10/100Mps Phyceiver transceiver found at address 1
sis900_probe: Using RTL 8201 as default
rtl8201_read_mode: Medialink on 100Mbs full duplex

I know. I remarked out (#) "authoritative" (along with every other line, for
that matter) which I assumed would force the system to read the ltsp
version. Curiously, webmin, under servers, only shows me the dhcp3 version -
remarks and all.

 It's /etc/ltsp/dhcpd.conf.  Can you check

It's on the system. Here's the whole thing:

# Default LTSP dhcpd.conf config file.


subnet netmask {
    option domain-name "";
    option domain-name-servers;
    option broadcast-address;
    option routers;
#    next-server;
#    get-lease-hostnames true;

    option subnet-mask;

#    filename "/ltsp/pxelinux.0";  [alternative to if/else option below?]

    option root-path "/opt/ltsp/i386";

    if substring( option vendor-class-identifier, 0, 9 ) = "PXEClient" {
        filename "/ltsp/i386/pxelinux.0";
    } else {
        filename "/ltsp/i386/nbi.img";

They were both in /opt/ltsp/i386/boot/. I copied them to /opt/ltsp/i386/ and
ran dhcp3-server restart but no change on the client boot.

Thanks. I really do appreciate this!
