thanks for the info but the link u referenced requires a working mac, which i do not have...there is good info there but most are post install issues i cant even get to the installer; still stuck at waiting for root device. i know there is a fix as i have seen many people with this issue resolved, but i cant seem to get it working as for the usb issues i got it worked it with the bios changes you suggested. thanks i keep looking

As for more info ok I am using Olarila OS X Mavericks USB bootable image from TPB I have tried both chameleon and clover boot options for the kernel panic problem i removed these /OS X Install USB/EFI/CLOVER/kexts/10.8/GenericUSBXHCI.kext /OS X Install USB/System/Library/Extensions/backup/IOUSBFamily.kext that got me past the kernel panic, but stuck at waiting for root device did some more research saw some people had success with 3rd Party AHCI kext, so i added that to the Extensions folder...but it did not work. Also tried AHCIDisk=1. npci=0x2000 and (0x3000), dsdt=null, usekernelcache=no, USBBusFix=yes none of these options have made a difference...maybe you have something i don't know thanks

Ok got a little further, seems to be a problem with USB kext, so removed them, now stuck at waiting for root device, so i tried 3rd party AHCI kext, no luck?? see attached screen shot any advice? thanks

Just built new PC and trying to install Mavericks for the past 2 days... finally got past loading drivers, now stuck at kernel panic, cant capture the screen, but it says something about UiMiIntiliaze invalid number of root hub ports?? Also something about AppleHDA failed to load?? Currently runnning Kubuntu and ran the system info from your site, everything checked out as ok for my system Ive tried some of the boot flags suggested from your site, but no luck (cpus=1,USBBusFix=yes, npci,graphicsenabler,PCIrootuid, -x -f -v) Any suggestions? thanks My setup Mainboard-Asus Z87-plus CPU Intel i5-4670k GPU-ATI Radeon HD4850 SSD-Corsair 128GB RAM-Corsair 16GB 2133 DDR3
