TOC results in (providing that the checksum passes) transfer of control to a routine pointed at from page 0. If something is trashing that, and the checksum'ed length is set to 0, then you'll branch off into the ozone. If the checksum fails, then you get the PDC default of rebooting. Don't know if that's your problem, but it's probably worth checking into whether something is trashing physical address 8 (TOC vector - 0xc is the length of the checksum.) lamont
