Hi guys,

Here is the beta AppleSMBIOSEFI I have been working on. It will work with original AppleSMBIOS but will try to fix or add some values that original AppleSMBIOS misses. Therefore, you don't have to worry about AppleSMBIOS being updated.

It is based on original AppleSMBIOS and it only works with EFI system right now. It is for both Tiger and Leopard. In addiation, it should fix "About This Mac" crash problem and wrong "Bus Speed" issue.

You can change the memory speed. Just boot with "memorySpeed=n" (n is the speed number you want)
You can change the memory type. Just boot with "memoryType=n" (n is the type number you want, 18 is DDR, 19 is DDR2)

Example:
memoryType=19 memorySpeed=533

Again, it is just the beta version and you still need the original AppleSMBIOS with it.

1. It will use value of "cpu->externalClock" first. If that value returns 0, it will use value of "FSBFrequency".
2. Add "FSB" flag. You can change the FSB value in case the value is still not correct. Just boot with "FSB=n" (n is the speed number you want) However, it doesn't update the value back to "FSBFrequency" yet.

Update: 7/2/2008
1. based on AppleSMBIOS-28
2. Added "serial-number", "board-id", and "system-type". The default serial-number is "W1234567890".
3. Released AppleSMBIOSEFI from memory after adding the values.
4. It should work both on Tiger and Leopard. (I used Tiger to compile the source code.)

P.S. CoolbookController won't work with AppleSMBIOSEFI_28 because model is set to "MacPro3,1". Try AppleSMBIOSEFI_28Air instead or change the model to the ones supported by CoolbookController.
