The second problem or more of a question is that is it possible to save the boot options so that it always boots in PAL-mode as now I have to always go to boot menu and set the PAL-mode on.
There are programs that will write a boot block that forces PAL or NTSC. Look for InstallSwitch in Aminet. Its a WB 1.x app tho, not sure if it will work on WB 3.1?
