I have eeepc 4gb running bt3 final on 4gb sdhc no problem
I installed as per the guide produced by pureh@te 02-20-2008
I followed this the only problem I found was /dev/sda or /dev/sdb depended on the order sd card or usb stick was plugged in.
this guide was for bt3beta and I found I did not have the 4 directories as per the guide but every thing works fine including changes.
Great guide should all work fine
to run wifi
airmon-ng stop ath0
airmon-ng start wifi0
ifconfig ath0 up
to test wifi run
aireplay-ng -9 ath0
you should now get injection working message
best of luck
