I'm new to embedded PPC Linux. Does anyone have a link to a good webpage explaining how to make a ramdisk- or flash-based CPU boot from the rebuilt kernel image I have? This is a Motorola MCIP805 CPU.
Thank you very much in advance! Regards, Bill Smith 214-654-5622 bsmith at iphase.com At 05:29 PM 9/9/2002 +0200, Wolfgang Denk wrote: >Dear Rod, > >can you please use a standard way to quote text?
