Fair point, I didn't cosider the copywrite aspect, bad idea to sell them with the mac firmware then.

Anyway i'm gonna order a few more, interested to see if these work in my Xserve G4 (which can be very picky when it comes to pic cards)

Hmm... Seems 10.4.11 breaks boot ability of my G3, gets to the gray screen then gives the no access sign (still waiting for rot device...).Was booting fine with 10.4.6

Edit: still boots fine in safe mode
