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



I was referring to booting with Etherboot floppies like you can get from Rom-O-Matic. These have always worked for me in the past, but not at all in 6.0.0.

One one particular one, for example, it boots from the floppy, (normal) gets an IP via DHCP, (normal) loads the kernel, (normal) and then fails with the "kernel panic" because it can't load the NIC.  I know how to configure for that and it is done, but it doesn't work. There is a 3com card in there and the option lines are configured, and the workstation has entries in the /etc/lts.conf to load the 3com card. like"NIC=3c509". And it doesn't work.  I have tried several different cards, adjusting the configs for each but to no avail.

It says:

ERROR! Could not automatically detect the network card.
input:ImPS/2 Generic Wheel Mouse as /class/input/input1
PCI cards. . .etc.etc.etc
Usually specified in option-129, in the
/etc/dhcpd.conf file. See . . . docs for info. . .

Kernel Panic - not syncing: Attempting to kill init!


I have the option-129 line set correctly.

I have the right computer name set in dhcpd.conf and also in the lts.conf for this particular workstation.

All to no avail.

Thanks for the reply. . .

Doug,

Once you get into antique hardware :) the rules change. PXE and
etherboot were not around at that time (I don't think) so getting them
to work is a serious challenge. The most used process is to have some
other method of booting available (floppy or CD or even a hidden flash
card with an IDE adapter.)

Some really old stuff _may_ be able to netboot _if_ the add-on network
card has a boot rom AND the mainboard is able to handle that. You would
need to have the "corporate" pc's as the home user style would not have
the BIOS capability.

By the time you get to an ide-flash adapter plus flash card you are
halfway to a new, tiny thin client that is very low power and fanless.
The power savings alone would cover the additional cost over a couple of
years. Plus desktop real estate is at a premium as well.
