I've tried both kernel 2.6.60.x and 2.6.8 from Ross Vumbaca's page.
I can use RawDisk to squirt the kernel into my Boot partition (RDB disk) which is MDH3B: (effectively a linux dd command in OS4).
however, once I'm in UBoot, and enter Diskboot 500000 0:3 0
and then type Bootm the boot process fails with a bad CRC error on both the 2.6.x kernels. Am I forgetting something ?
