Hi Bimal,

And the eth1 card
Intel Corp e100 82801BA/BAM/CA/CAM Ethernet Controller
And the eth0 card
Realtek RTL-8139/8139C/8139C+ 8139too
The client says now:

Aug 28 10:57:10 server dhcpd: dhcpd startup succeeded
and did a search on google for the PXE-E52 error
and got http://riv-mail.mesd.k12.or.us/mailarchives/k12ltspdig/306.html
where the writer says: "What version of pxe does
your client have? I've had success with 2.0 but not with .99."
My client has .99
So I've switched the cable to a different client, the one specified in
host ws001 {
hardware ethernet 00:0E:A6:65:E2:29;
Restarted with a boot floppy... and receive these messages (some but not all
copied - by hand!)
Etherboot 5.0.1
found VIA 6102 at 0xE800, ROM address 0x0000
probing... [VIA 86C100 lrhine.c V1.0.0 2000-01-07
IO address E800 Ethernet Address: 0x00:0x0E:0XA6:0X65:0XE2:0X29
Analyzing media type, this will take several seconds... ok
Linespeed=100Mbs Fullduplex
Searching for server (DHCP)...
<sleep>
ARG!!!!
ok so it is not a problem with the client, yes?
I am going to try buy a new switch and a new network card to cancel out
those two as possible problems.
I know it shouldn't be this difficult... I think I must be missing something
very obvious... So I will keep on until I get it right!
Thanx for your help.
Best regards,
Debbie
