My DVD drive is SATA, but per your suggestion I hooked up an IDE DVD drive.
Problem was not resolved.
If I type '80' it recognizes my HDD, and obviously since it is a blank drive (Formatted Guid) if I press enter I get the error message
System config file '/com.apple.boot.S/Library/Preferences/SystemConfiguration/com.apple.Boot.plist' not found
I am using a legit retail Leopard 10.5.1 disk
If I type '?' and press enter nothing happens
both -v and -f give the error message
'escape' brings me back to the screen with options of entering two-digit hex device
Im at a loss, but Im a noob too so...
