- No, the S3 (82c911) and ET4000 (Tseng) are definatly NOT compatible on
- register level, so I'll doubt X11 running on it (with ET4000 drivers)!
- Of course, there might be S3-drivers too, but I'm sure about it.

- There are palette chips out there that can do
- - 256 out of 256K
- - 256 out of 16M
- - 32K fixed
- - 64K fixed
- - 16M fixed
- combinations of the above are possible and available.
-
- But there's no such beast with 32K out of 16M neither announced nor
- available (at least not from Sierra, AT&T, Brooktree or Inmos).
- I know since I looked heavily into that stuff recently...
-
- Ciao, Klaus.
