NAME

6       vga_setchipset - force chipset

SYNOPSIS

9       #include <vga.h>
10
11       void vga_setchipset(int chipset);
12
13

DESCRIPTION

15       Force   detection   of   a  chipset  (when  chipset  detection  fails).
16       vga_setchipset(VGA) can be useful if the chipset specific stuff or  the
17       SVGA detection stuff gives problems.
18
19       However,  at first the automatic detection should work well, and if not
20       a specific chipset can be forced from /etc/vga/libvga.config.
21
22       Because of that, void vga_setchipset(int chipset) should probably never
23       be  used  by  applications.  If  used nevertheless, it should be called
24       directly before vga_init(3).
25
26       As of now the following values are defined for chipset:
27
28       UNDEFINED
29              This is the default and specifies autodetection.
30
31       VGA    A plain VGA card, not that the SVGA must behave like an ordinary
32              SVGA  card  then  which  will probably mean it is in an ordinary
33              (25x80) textmode.
34
35       ET4000 Tseng ET4000/ET4000W32(i/p) cards.

41              cards.
42
43       OAK    Oak Technologies OTI-037/67/77/87 cards.
