Warren is trying to do the foolish task of figuring out if Apple MAC address prefixes are unique between PPC and Intel Macs. Please e-mail wtogami at redhat dot com if you have any MAC not already listed to add to the prefixes listed below. I especially want to know if you found a MAC address that upsets the trend.
Built-in Ethernet only! I only care about netboot, so wireless and add-on cards are not important here.
Why is Warren doing this? DHCP server has no other way of knowing the client is a PPC to give it a PPC netboot root-path. DHCP server can see the AAPLBSDPC vendor-client-identifier and correctly gives it yaboot, which then downloads kernel/initrd and boots Linux. But the initrd does DHCP discover a second time with the unhelpful vendor-client-identifer "nash", where it cannot differentiate i386 and PPC.
