9.1 beta 2 on G4 PowerBook 12" some questions

[vgeloven]

Hi all,

I've been reading a lot of emails in this list but was so far unable 
find info on these things for installing 9.1 beta 2:

- what should I select fro bus /usb

- what should I select for sound

- what should I select for X-Windows

- how do I format the bootstrap partition by hand

- how can I boot newly installed Mandrake from Open Firmware, boot 
hd:11,//?? or something like this

Thanks,

Sander
