Using an Atheros Wireless Card on DRBL

Hello,

I’ve recently been testing a new driver addition to the gPXE project which allows a PXE boot over Atheros 5k-based wireless adapters. (Project details here: http://etherboot.org/wiki/soc/2009/oremanj/journal/week12)

I have an Asus EeePC which uses this wireless adapter and I would like to be able to boot a DRBL image over the wireless adapter. Currently, I can initialize the Atheros wireless card using the new drivers in gPXE, connect to the network, request DHCP from the DRBL via PXE, and do an initial boot via TFTP. During the initial boot, however, the machine hangs saying that it cannot find a network card and cannot continue.

I’m wondering what would be the best way to integrate the proper Atheros driver I need, as well as the wireless SSID and key settings, so it can carry on with mounting the NFS shares and continue to load the rest of the OS as it would with a wired NIC.

I’m running this on a Ubuntu 7.10 server with kernel version 2.6.22, so the Ath5k/madwifi/ath_pci driver I need should already be compiled and ready to go.

Thanks in advance,

Corey

Hi Corey,
This is really interesting.
What you have to do now I think is you have to modify the package
mkpxeinitrd-net from DRBL.
1. In the file /usr/bin/mkpxeinitrd-net, you have to add the drivers for
the wireless network.
2. The busybox which comes with mkpxeinitrd-net does not have "iwconfig"
command, so you might have to insert the command from your GNU/Linux
system to the created network initramfs (remember some libs you also
have to insert).
3. In the file /usr/lib/mkpxeinitrd-net/initrd-skel/linuxrc-or-init, you
have to assign wireless SSID before it requests IP address from DHCP server.

I will try to test here recently. If you make it, please share that with us.
Thanks.

Steven.
