Hi, sorry that I answer this late to your post, but I've been rather busy the last few weeks so no time to use my Hackintosh.

I've looked all over the disk and my HD, but I haven't found any /oah folder... sorry.

Regarding 10.5.5 and unsuable, I could not even type any flag command for the machine always hard-rebooted itself before the option even came up. So, no last message, sorry.
