Hi,
I'm trying to boot original 440GP "Ebony" board wiath original IBM ROM Monitor:
...

	440GP 1.18 ROM Monitor (02/11/02)

...

However I've discovered that it requires special image in KDI (Kernel Downloadable Image) format. And it seems that the only way to make such image is to use 'mkimage' utility from LynuxWorks which is not widely available :-)
Can anybody help me with this?

thanks in advance,

P.S. For some reason I cannot replace ROM Monitor with U-Boot on this board.

Huh? I'm away from my Ebony right now, so I cannot check which OpenBIOS version it has but I never heard about KDI.

Image generated by the make bzImage in 2.4 or 2.6 official kernel should be bootable on Ebony with original IBM firmware.

Why do you think IBM firmware requires LynuxWorks special image? This sounds like a nonsense, frankly.

I also thought similar, but:

- make bzImage within stock 2.6.9 gives me zImage.elf
- when trying to boot Ebony with it I have:

Booting from [EMAC0] Ethernet 0 ...
Sending bootp request ...

Loading file "zImage.elf" ...
Sending tftp boot request ...
Not a valid boot image file

And I'm completely lost with this :-)

regards,

You should use arch/ppc/boot/images/zImage.ebony, not zImage.elf

Correct OpenBIOS image has "\0RPO" at the beginning.

Thanks,
the problem was buggy OpenBIOS v 1.18 (problems with EMAC). After upgrading to 1.19 everything works fine.

thanks,
