Log Message:	Issue a SysError(dsOldSystem) if we are trying to use MacOS < 8.1.0 with a NewWorld ROM. That may be 8.1.0 included but original iMac had a NewWorld ROM compatible system. Otherwise we will crash because the boot routine is trying to execute code through unitialized descriptor that points to 0x13ff, which is obviously wrong (and unaligned on word-boundaries for 68k code).
