boot rom

I have a macpro1,1 . after doing some reading, i found that snow leopard will not boot to 64bit kernel unless the EFI was something etc etc

Anyone know anything about this and or if i can upgrade these items?

Its doubtful that it will be upgradeable, and even if it is, it makes little difference, all your applications can already run in 64 bit mode and address gigabytes of RAM.

You cannot upgrade it.

And why do you want to boot K64? It's like K32, but less of your stuff works with it. 64bit mostly matters for your applications, which will work just fine in 64bit regardless of which kernel you are running.

Read the other threads about it. No, MP1,1 and all other 32-bit EFI machines will not boot into 64-bit kernel. It is probably a minor trickery required to make it boot but not in the official firmware.
