RE: [E1000-devel] kernel parameters

[Brandeburg, J. <jes...@in...>]

Hi Heiko,

First, since you cannot pass those driver options on the append=3D line =
you have a couple choices left.

1) modify the kernel source, just change the default for the value =
you're interested in in e1000_param.c

2) start using initrd files, as I'm almost positive you can put the =
e1000 in an initrd file, and set up /etc/modules.conf to pass load =
options to the kernel module.

Sorry if you have already tried the initrd way, as in my opinion it is =
the best way.  Let us know what you end up doing!

Jesse
