-
- I mean that when a piece of kernel code is loaded, it stays in memory
- unless it's a loadable module that subsequently gets unloaded.

-
- Perhaps the speaker *meant* to say that they could be *unloaded*....
-
- SunOS 4.x doesn't, as I remember, officially support loadable SCSA
- target drivers. 5.x, I think, does. *That* may be what the apparently
- rather confused speaker was trying to say....

-
- Nope; you were, it seems, the only non-confused person in a room of 150
- extremely confused people. 4.x's kernel is *not* pageable, and anybody
- who claims it is simply doesn't know what they're talking about.
