Log: hfsplus: Fix disk support for disks > 4GB
The HFS+ driver was truncating the end of the disk to 32bit implicitly by multiplying a 32bit value with another 32bit value. Cast the first one to 64bit, making the result 64bit wide as well.
This fixes booting from big disks for me.

Yes, I'm booting from the 10.4 install image for a while now. It just doesn't find its root device yet. I found that particular issue with a ready-installed 10.4.11 image that I had created earlier with MOL. I was planning to use that to debug the guest with self-compiled kexts.
As a nice side-effect, I can also boot my leopard DVD as well now. Though that one really does complain about the g3beige ;).
It looks like whether booting works is very timing sensitive. It almost feels as if DMA transfers are racy, but that's really just a wild guess.
There might be a timing issue involved.
How did you make your DVD image files? I used Disk Utility and made a DVD Master file. Then just changed the extension to iso. This way worked with CDs. Just not with DVDs. Are you able to view the contents of your DVDs in OpenBIOS using the dir cd:,\ command?
