I've successfully installed Mac OS X 10.5.6 using iPC. But when I try to boot up it gets stuck on Using (number) buffer headers and (number) cluster IO buffer headers. Only solution to that is to insert iPC disk and boot up like this:
cpus=1 rd=disk0s2 -v "Graphics Mode"="1280x1024x32"
Result: Boots up correctly, but no sound Whatsoever despite installing VoodooHDA, Azalia Audio and AppleHDA.kext. Tried installing ApplePIIXATA but that made it worse and actually started a kernel panic so I had to reinstall the whole thing again. Please help me on this one.
