Mac128,
I appreciate your emailing me a disk image. The "mfs400k" image you sent me last night had problems again -- I couldn't get DD+ or DiskCopy4.2 to mount it UNTIL I changed the TYPE and CREATOR to what DD+ wanted to see (DD+ formatted image) and then it worked! So I make a 400k floppy with it, switch on my HD20, waited 30 seconds, switched on my Mac512, then inserted the disk made from your image. It got to the Welcome to Macintosh box and then my HD20 started accessing and the disk was ejected. But a second later the Welcome to Macintosh box started flickering (i.e., computer crashed), just as I reported in my last post.
Now although I would normally suspect the disk as being bad, the fact is that if I switch off my HD20, I can boot from your disk! And yes, the HD20 INIT on that disk loads.
I then proceeded to swap out Finder 5.0 with Finder 4.1. Tried making the 800k MFS disk, but it would only create HFS. So it's clear that I need to do the ResEdit hack on it to enable the MFS formatting for 800k disks. I was brain-dead tired after work this evening, so I didn't feel up to ResEditing today. Perhaps I can do that tomorrow and report back here.
But suffice it to say, despite the fact that this System and Finder should theoretically boot my HD20, my findings are that it doesn't work. Like I said, the Welcome to Macintosh box flickers/freezes after the disk is ejected at boot time.
