I have a stable AMD machine using Zephyroth's Leopard 10.5.2 rev2 (now updated to 10.5.5).

I am using the standard Darwin bootloader (non-EFI), but I am curious if there's a difference between this and the PC_EFI v8.

This is simply a question to satisfy my curious mind on the difference between the two and possible advantages and disadvantages both has on a machine.

Also, I'm using MBR partition. I know PC_EFI v8 cannot be installed on MBR, yet I read on another forum that it now can.

How to update from 10.5.2 to 10.5.5

I also loaded Zepy's 10.5.2 and the bootloader working fine in SATA drive.

How did you update 10.5.2 to 10.5.5? I tried using ASU while extracting the monitor showed reboot and nothing worked. I reinstalled 10.5.2 again.

Any help in updating to 10.5.5
