I install 7.0 + 6.0.7 on the hard disk which is formatted under driver version 2.2.8 and I use system switcher 1.1 to switch between the two systems. When I boot the System 6.0.7, the message "Welcome to Macintosh" disappears. Moreover, I run MacTools Deluxe and it shows the catalog files and the boot block are damaged. I phoned Ehman Company this morning and they are going to send me a new driver of version 3.29 for $15. This version will not work either if one is going to use VM. Version 3.4 will not be available until next month.
