GA-H55M-USB3 reboot loop and/or reboot hang. HD boot no go.

GA-H55M-USB3 F11 downgraded to F10
Intel Core i3 540 3.06G
Kingston DDR3 2GB Bus 1333Mhz (2 Modules)
Hitachi HD 1TB SATA 7200RPM 32M
No graphics card (using video from DVI on MB)

Hi Community:

I am trying to build a system with the excellent iBoot+Multibeast method this are my troubles any help is appreciated:

First Attempt:
(Using 1TB partition or using two 500MB partitions)
iBoot + OSX 10.6 DVD + 10.6.5 Combo + Multibeast - Install OK
iBootGE + OSX 10.6 DVD + 10.6.5 Combo + Multibeast - Install OK
Upon reboot, iBoot from HD kicks in then gray mac booting screen hang (little "sun-like" icon going round n round forever).
Using option -x -v, boots lots of things, then when darwin starts certain things boot up but then hangs on line:

disk1s1s2: iodl(_ior, "d", 79, 4) is unsopported.

Doing a reboot with iBootCD -x -v and Snow Leopard hangs too.

This happens too with these scenarios:
iBoot + OSX 10.6 DVD + 10.6.4 Combo + Multibeast - Install OK
iBoot + OSX 10.6 DVD + 10.6.3 Combo + Multibeast - Install OK
iBootGE + OSX 10.6 DVD + 10.6.4 Combo + Multibeast - Install OK
iBootGE + OSX 10.6 DVD + 10.6.3 Combo + Multibeast - Install OK

Second Attempt:
(Using 1TB partition or using two 500MB partitions)
iBoot + OSX 10.6 DVD + Multibeast - Install OK
iBootGE + OSX 10.6 DVD + Multibeast - Install OK
Upon reboot, iBoot from HD kicks in, very briefly screen with a progress bar at bottom appears followed by a total system restart (reboot loop).
Using option -x -v Wait=Yes boots lots of lines and stops before Darwin Start, pressing enter immediately restarts the hole CPU from start.

Upon reboot using iBootCD and selecting Snow Leopard, it boots without a problem. Here I can work with system ok (install things, copy, paste, use Multibeast, etc) but I can never make it boot from the HD. Even sound works ok!

In a nutshell, currently the only way for me to use the system is to make a fresh install using iBoot + OSX 10.6 DVD (or iBootGE) upon reboot using iBoot cd to login to Snow Leopard.

Any pointers greatly appreciated.

Regards!

The Intel integrated graphics controller is not currently supported. You need to add a graphics card.

Hello MacMan

I guess... I did not read enough!

Thanks for your answer and patience, a compatible graphics card solved the problem.

As stated, a compatible graphics card is mandatory when using 10.6.5 combo and a Core i processor. What had me going round and round for a while was actually seeing video from the 10.6 install with the Intel Integrated Graphics Controller.

This helped me alot too. I know I have a totally unusable Radeon 4850 so I thought "hey I can boot with the GMA HD Graphics, let's just update" and then after updating, nothing but spinny beach ball. Might as well get the system prepped for the new nVidia card, right?

Wrong. Safe mode didn't even work. I figured I could use 10.6.0 with an unsupported graphics card (even if I was stuck with 1024x768) so I should be able to do the same with 10.6.5. I was wrong, it would get stuck. Guess I'm really going to have to wait til I get a supported graphics card before proceeding.
