Hi,

Be sure to pay attention to some components this guide ask you to remove. You need at least PCMCIA and .net working. I also think i kept bluetooth.
NB: speaker client do not work here and i have not investigated that further.
But you need at least 1 gb of HDD . .net is needs about 200mb alone when installed. I have a 2gb HDD (a 100 usd upgrade)and have about 1 gb free.
