OK, so I have successfully installed OSX 10.4.3 with JaS and maxxus patches on a Toshiba s149 notebook (used Pacifist to extract IO80211.kext from 4.5 update to get WiFi up), and a P4 desktop with ASUS P4P800-E. Now, I'm trying to install on a machine with the following: ASUS P4P800SE modified with CT-479 for use with Pentium M (725 in this case)... tried with and without modification (using P4 off the other board) and the OS never begins install. Boot Graphics never initiated, but I could see an entry in Darwin that states "EHCI unable to take control of BIOS" has anyone heard of this incompatibility or have any suggestions? thanks!

Does this adapter support CoreDUO processors?

No, only the older (Dothan and below) Pentium-M processors.
