I assume that you are talking about
the CMOS setting menu you get after pressing a key during boot, F2 for
my laptop, although often the 'delete' key for other computers.

On my laptop there isn't an 'Advance' tab. Vista works perfectly, and
starts up with the wireless enabled. There is an button which toggles
it on/off and lights up when data is being transferred.

There seems to be quite a variation of BIOSs around, so perhaps this one
has the wireless always enabled on boot and controlled by the push
button?

Re the 8.4/8.10 bit. 8.4 may have a driver for you W/lan 8.10 may not.

At the present time I'm not in any great hurry to get this working with
Ubuntu and will wait until I can get a DVD with 9.04. Hopefully this
will have the problem sorted out
