No.... He's looking for a bootblock you can install on floppies so that you have a boot-time PAL/NTSC option. I had two... One of which I think was the "SwitchInstall" (which I don't remember NOT working on WB 2, but I'll assume that's correct) and the other was always detected as a Virus by several scanners (though it never seemed to harm the disk it was installed on -- just turn off the computer after you were done with it! :lol: )
I really wish I could remember what the last one was called, and if I ever got either of them to work with WB 2.x. Of course, thinking about it for a second.... Would you really need a bootblock switcher? For WB 2+, couldn't you just replace the NTSC monitor device with a PAL one, if you have ECS Agnus?
