- hello
-
- a problem: Setscreen (-1, foo, -1) sets the displayed screen address
- and GEM (VDI) still writes to its old one. now how do i set the displayed
- _video mode_ for the screen at adress foo without affecting GEMs too?
- seems only by hitting the hardware directly. :-( question: has someone
- code for that which i could use that works on TTs or falcons too?
-
- the reason is, when the console screen now takes 300K on a falcon
- (hi res, many colours...) virtual terminals (vt01..09) now would take
- 600K for the first and 300 more for each other open vt... although they
- are just text screens where for the usual 25 * 80 characters ST video
- modes should be as good (32K), and faster too.
-
- i guess just code that saves/restores the hardware register settings in
- the right order and timing would be enogh... then i could do a normal
- Setscreen once at boot time and then just use the saved settings?
-
- thanx...
