Otherwise the gettys started from /etc/ttys on /dev/ttyvX will cause the thing to panic. Of course, you will fix the /etc/ttys to not start them, but the idea of a perfectly ordinary /dev entry which will panic your system hopelessly if you ever touch it gave be the willies. I wonder if the sc0 probe code should write and read back the MDA video memory as well as, or even instead of that broken keyboard probe? I never hacked on my boot blocks, but they seem to get along without video hardware alright. ============================================ Gardner Buchanan <gbuchanan@sympatico.ca> Ottawa, ON
