ACK! Three failures for Yosemite, cant guarantee support in Mavericks. Its geting hard to find images that work. I have a CrosshairV in one system, use a Samsung w AMD APU in another (laptop) and the third is an Acer POS AMD APU from WalMart. Video cards vary. The tower has 2xHD7850 Radeons. I either get the following:
1) stuck at boot spinner loading text and zero boot loaded(Tower)
2) graphical boot options but kernel reboots on load (laptop with external HDD written to, then inserted as master HD) --no option to specify settings, must use preselected options
3) bootloader works in text mode but kernel reboots on load
I cant get around the kernel reboots.Ive tried every option I can think of. (GraphicsEnabler=No UseKernelCache=No PciRoot=1 -v -f -x) This issue has persisted since the initial so called AMD releases from Leopard/Snow Leopard.
Ive only gotten the Intel builds to work in the past.(GNT945 mobo and 3+Ghz CPU)
Id like to figure out where the kernel loading issue is coming from.
What makes this more complex is the laptop wont boot USB devices and the Tower doesnt like UEFI partitions on hard drives.ASUS wont fix the UEFI issue.
