Apple software raid boots fine here with clover. (from external usb stick)

OK. I have educated myself some more in the graphics uefi part . It's very simple. The addon pcie graphics card needs a vbios with UEFI GOP. Sadly my MSI Geforce GTX670/OC doesn't have that. There was a uefi update for my motherboard yesterday that adds UEFI GOP support. If I try to enable 'ultra fast (windows 8 feature which requires UEFI GOP) ' it states that my videocard does not include UEFI GOP. Mailed MSI in the hope they have a hybrid vbios.

I am guessing all the resolution stuff is also handled by this?

It's not a 'waiting for root device' but total system lockup/freeze after the kernel boots. (Not always, random after restarts)  I have to reset the machine.
I think its UEFI related, because BIOS/Legacy Clover always boots without problems. Maybe something in one of the uefi drivers. (tried all the combinations) or I just have a wacky uefi. (asrock extreme 11)

Clover also gives in bios mode a very quick warning flash 'There is a TSC detection problem and needs calibration' before displaying the gui boot menu. (Also in system log in OS X). (I have to voodoo sync kext installed)

About the graphics.. chameleon boot menu has a resolution/vesa of 2560x1440x32 when the resolution is specified in org.chameleon.boot.plist if graphics mode is not specified the graphics/vesa resolution is 1024x768

clover bios mode gives me 1024x768
clover direct uefi gives me 1024x768

but thats is just how the implementation works I think if bios mode is just a extra layer to emulate all uefi.

(all geforce gtx 670)

I will try the radeon card tonight.

lol! I thought -f was working because it booted. Well that's pretty stupid. Did some more tests and it just really random if it boots or hangs. Kernel will just lock up sometimes.. and this is a issue with mountain lion and not lion. Hmm weird stuff. (Have 2 installs)

About the UEFI ROM. I am guessing IF the videocard itself contains an efi rom, it would display the correct resolution? The motherboard uefi will read a PCIe efi compatible rom and load the resolution table? If not it would load the bios compatible (most pc cards) rom and defaults to 1024x768 or lower? I have option in my uefi to to toggle priority on PCIe Cards  'legacy rom' and 'efi rom' if that makes any sense.

I have a 'old' Radeon HD6870 still flashed with an efi extensions. Maybe I'll try that when I have the time.

I have everything working fine now with clover and raid boot . Though I have to -f to startup if not it would hang. Kernel cache isnt always reliable here. Sometimes it starts without -f sometimes not... (I would get some memory map error with the same memory codes or something after 10 secs it starts).

Also did a msr dump. This is normal for my i7-3930K @ 4.2ghz right?
