- You can't upgrade non-Indigo's to that OS release, unless they
- have reality engine graphics; 405F (the r4k indigo release) is
- not a general release.
-
- There shouldn't be any compatibility issues, although of course
- there will be slightly different bug lists on the various machines
- (fewer on the later releases, we hope!).
