- I'm not sure. Maybe, the four trackdisk devices may have their fssm in
- ROM. But normally, the fssm is allocated by Mount and so in RAM.

- Maybe you will miss DF0:, DF1:, DF2: or DF3: in future... But what do
- you think about the following checks:
- - (dn_Startup<<2)>=1024
- - AllocAbs ((dn_Startup<<2), x) MUST fail

- No enforcer hits und no nonstandard dn_Startup. I think if a program
- like DiskCopy crashes with these device, I may crash too, if there is no
- good way to avoid crashing. Flames to /dev/nil.

- DF0:, DF1:, DF2: and DF3:. I'm not sure, but I think it was using
- KS 1.3. But maybe I'm wrong and was OS 2.04. But the fssm was in RAM.

- I will be away until 10-Jan-92. So don't wonder why I don't answer...
