- AFAIK (from the schematics 8) there is an MFP in there, but the serial lines
- don't go anywhere (which is a pain, there are some free drivers in there too
- 8( )
-
- The falcon serial interface is run on an SCC - I can't tell whether this
- is arranged as with the SCC in the TT.

- Hmm, more scope for loadable ones I think - in fact, I am _sure_. Myself,
- I'd like to see all but the TOSFS driver loaded at startup rather than linked
- in. (I know this may be unreasonable, I haven't looked at it yet).
- Then the kernel should go looking for the appropriate drivers for the
- current hardware, and load any user-supplied ones. (you'd probably do it
- with a small tree structure :
-
- \mint
- \mint\system
- \mint\drivers
-
- or similar. Who knows - it would be nice. So would AiNA (you guess 8)
