Re: [K12OSN] 3com ISA NIC Booting


There were big changes between K12 1.1 and 2.0.  The biggest
change that I know if is that K12-2.0 is based on LTSP 3.0,
which was a major change for LTSP.

Indeed, the network drivers are compiled as modules on LTSP 3.0.

PCI network chipsets are automatically detected, but ISA chipsets
are not.

If you want to make it work with an ISA card, such as the 3c509, you
will need to pass both option-128 AND option-129.

For more information, take a look at this document:


Down near the bottom, you'll find important information for
configuring ISA network cards.
