Greetings all,
here's a bit of information which some of you might find usefull.
I have a problem and a solution which some of you might find
helpful.
The Problem:
+ I need the get LTSP to load an alternate NIC as eth0
The Environment:
+ I have Fujitsu Scovery system (onboard eepro with old broken PXE)
It only worked in the past with BPBatch
+ I cannot disable the onboard NIC (no such bios option)
+ I installed a 2nd NIC (Broadcom Gigabit with PXE Bios)
+ The broadcom card always loads as eth1 (not eth0)
The Solution:
+ No modifications to LTSP, but merely some dhcp vender encapsulated options
+ comments are in the attached dhcpd.conf file
+ Passing NIC=tg3 on the kernel options for the LTSP kernel causes the linuxrc
to load the spicific driver instead of running pci_scan.
Here's the dhcpd.conf:
ddns-update-style none;
option subnet-mask 255.255.255.0;
option broadcast-address 192.168.1.255;
option domain-name-servers 192.168.1.102;
option domain-name "foo.com";
option option-128 code 128 = string;
option option-129 code 129 = text;
shared-network WORKSTATIONS {
subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.200 192.168.1.210;
}
}
group {

option log-servers 192.168.1.100;

## Option 128 is ETHERBOOT specific and enables option 129
## Option 129 passes appended parameters to the kernel, and NIC=xxx
## merely sets an evironment variable which the LTSP linuxrc
## happens to use to determine which nic driver to load
## If unset (default) linuxrc invokes pci_scan which in
## my case blows up because I have 2 nics (tg3 & e100)
option option-128 E4:45:74:68:00:00;
