Are you sure you are getting the correct contents of those ROMs? Would it be worthwhile to try and get the author of the ROMs to add standard ROM headers? The content you included doesn't look that useful unless that is what IA64 instructions look like. If reading past 1MB for those ROMs causes a reboots, could something be wrong in the IA64 fault handing code? I'd feel a lot better if someone actually tried this patch on a ppc or sun machine. ===== Jon Smirl jonsmirl@yahoo.com _______________________________ Do you Yahoo!?
