Wolfgang,
I think I understand the solution. But I'm not sure.
Are you saying. Create a partition which is not formatted with a file system and whose sole purpose is to contain a kernel image. Then, modify the diskboot command to read the contents of that partition into memory and execute.
Regards, Mark.

You have to adapt the existing IDE/ATA code so it can talk to your IDE controller. Then you can use the "diskboot" command to load a kernel image from a disk partition.
I'm in the process of completing a port of U-Boot to the Motorola
PrPMC800
which is uses a PowerPC MPC7410 processor. My goal is to have U-Boot
boot
Linux from a hard drive instead of from flash. I've just completed the

PCI/IDE support for this. I thought I could have U-Boot load Lilo or
Grub.
What the h*ll do you need lilo or grub for? You got U-Boot! :-)
