Re: [K12OSN] Support for Etherboot on 486's with ISA NICs



I killed the other DHCP server. There is only one running at a time.

Thanks for the input. . .

P.S. I did finally get it to take the boot as far as the NIC is concerned, but now am trying to get X to load. . .

Progress. . .

Thanks again!

Man I suppose that you have 2 dhcp servers running....
maybe thats is the problem...
Your client target to other dhcp server that no have the option to handle
old isa netcards...
I have long time ago this ttrouble.... A router has a dhcp server too... and
when ltsp boot ask for second time dhcp appear this error: no nic... kernel
panic... etc etc...
The presence of other dhcp server running is the problem...
I try to help with my little acknoweldge...
