Do you have siliconmotion502.chip in your Kickstart?

Of course not :) Just default pegasos2 install cd :) I just thinking about it always, but somehow were sure i should see some output after 100% loading done, like "missing" , or some crash, or like kernel says something, etc..

You can also set os4_commandline env var to get serial debug and use kernel.debug to see if kernel starts or not.

At least even with original firmware, when i boot to OF, and do "setenv os4_commandline test" i have "no such configuration variable", i should dig in into notes i am sure it was something simple..

Just can't stay away

You could see output with os4_commandline set but that's also not default and on pegasos also needs to be defined with nodefaultbytes (there's a Forth script called bootloader_prepare for that on the install CD that you can call). And you need to do that at every boot because NVRAM is not emulated on QEMU so saveenv has nowhere to save.

I simple create in OF code this variable being set , and after boot can simple do "setenv" , and yes, then:


gfx AltiVec/VMX enabled

gfx PPC74xx optimizations enabled

graphics.library cannot configure your graphics board!Either your board is not supported or there's a configuration problem.Did you install PCIGraphics.kmod?

That it then :)

ps. Making morphos boots too now. So some basics works. Next probably need to try to add x86 emulator, probably Uboot's one i use for patch for CFE can be used (hope it will be no slower than one in original firmware).
