hi guys,
i have been reading this post as i have 6920g with just about everything running under ideneb. just got wifi working by adding a dell 1490 card in 2nd pcie slot with aerial wires (wouldnt work at all in first one) and just left my standard intel where it was. did the pin20 trick so its on all the time as acer whitlisted it to not let me switch when using windows. for dual booting i use 'boot-it' which i highly recommend (no connection) i can set the mbr so that only the one partition to which i am installing an os to is visible. after install you just set other partitions to be seen by each os to suit. i have leopard and 4 different windows plus 2 data partitions with no problems
