I'm trying to install gentoo linux via network, and I'd like to make grub with diskless options.

./configure --enable-diskless

At this time, I have to add driver option (like --enable-rtl8139), but my PC's (eEEPC 701) network device is "Atheros L2 Fast Ethernet 10/100 Base-T Controller". Grub has no option for it...

Is it possible use grub for network install in this case?
