I get that processor tray serial number line in system profiler when booting with clover. But I don't get it when booting with chameleon. I use the exact same smbios values for both bootloader. So the only difference is the bootloader itself. So something is wrong with chameleon.
Btw I used imac9,1, imac10,1 and all works fine but with imac smbioses, I'm getting the soundpop bug. So that's why I use macpro3,1.
As you can see on screenshot above i got processor sn in sys.prof. even with MBP6,1 smbios. booting with Chameleon Chameleon_i386_v2269test2.zip 1.01MB 0 downloads
