I've just installed Mac.OS.X.Tiger.10.4.6.X86-HOTiSO and followed the instructions listed here http://www.nedprod.com/Niall_stuff/MacOS%20X/index.html .

The installation went perfectly (apart from at the end the reboot thing didn't work so I had to manually switch the PC off).

I'm running a 2.8GHz P4 HT which afaik is fine to run OS X.

I cannot boot into OS X using chain0 because it reports a chain booting error nor can I use Acronis to boot into OS X because Acronis can't find it! However, Acronis does see it as a primary 0xAF partition.

Any idea what is wrong?

How did you set up your partition table? I know I could never get my osx to boot when it was on a partition using chain0.

I set it up as written in the guide.

"Boot the Linux DVD and go into Rescue mode. Run fdisk /dev/hda and print the partition table using 'p'. If there are any warnings at all, you must fix them (eg; partition table not in order, or cylinder end not correct). PartitionMagic doesn't always get this correct and FreeBSD's installer is notorious for screwing up your CHS compatibility table in way you normally never notice (as everything uses the LBA table). Change the type of your destination partition to hex 0xaf using the 't' command. Write table to disc using 'x' and reboot using the MacOS X DVD."

Everything ran so smoothly until I tried to boot! agh!

Incidentally, when I install it (I've tried three times now), it completes the installation and attempts to reboot... but I wait and wait and it just doesn't reboot so I have to manually switch my PC off. Maybe it has something to do with that?
