Optimize kernel for Xserve

[Andreas Pack]

First, thank you very much for the details answer an for your
configuration file! :o)

Hmm... ok, but I found the Tigon3 (tg3.0) support in
kernel-source-2.4.20-0.7d :) - I only need one gigabit network card.

Btw, is it enough to compile "Broadcom Tigon gigabit" as build-in (not
as module) or do I have to change something elsewhere in the
network-scripts or configuration files?
SuSE would use a module like this "alias eth0 tg3" in modules.conf i
think. But how do I associate an ethX-device to build-in modules with
YDL? That would be interesting for me.

Roger :o)

Yes, I looked in the kernel source for marked ethernet cards, but i'm
not really experienced with macintosh-hardware :( (I come from X86
machines). Sun GEM was one of many supported cards and I was not sure
what to choose. But apart from this, my main intention was to get the
gigabit-network card working.

This information is like gold for me ;o)

Yes, I know and I tried lspci, but that is my result:

00:10.0 Ethernet controller: Apple Computer Inc.: Unknown device 1645 (rev 15)
22:0f.0 Class ffff: Apple Computer Inc.: Unknown device 0032 (rev ff)

Also if I run lcpci like this:

lspci -i /usr/src/linux-2.4/drivers/pci/pci.ids

Do I have to compile the benh-kernel before that works?

THX again :)
