do you want to use your apple wireless keyboard on any pc?
i've successfully tested the special keys (includeing FN-KEY) on my vista ultimate x64.
apple wireless keyboard
leopard 10.5.2 macosx dvd (including the bootcamp drivers)
first of all i made my wireless keyboard working with my pc. (blue tooth key, ...)
then i installed sharpkeys http://www.randyrants.com/sharpkeys/ and changed some keyboard mappings for german keyboard (<> ^°, right-alt to delete,(screenshot))
insert bootcamp dvd and start AppleKeyboardInstaller64
ive noticed that keyboard now was correctly identified as apple keyboard HID-device
i thought creating a systemrestorepoint could be useful and then i installed the bootcamp64.msi.
reboot an the apple wirless keyboard was running fine with fn-key and media function ;-)
fine-tuneing: i setup to use F1-F12 keys (not the media keys) to be the default function.
special thanks to following site which gave me the idea installing the bootcamp drivers ;-)
