Certainly if there were some funding available, this is something that I could look at if required. Currently my free time is limited (and already fairly busy) but with sponsorship there is the potential to allocate time within the working week. I must say I'm surprised that HFS+ doesn't boot - certainly I see images in QEMU that require both, and OpenBIOS has booted them successfully for many years. ATB, Mark.
