vga_setchipset (3)
force chipset
SYNOPSIS
DESCRIPTION
Force detection of a chipset (when chipset detection fails).
vga_setchipset(VGA)
can be useful if the chipset specific
stuff or the SVGA detection stuff gives problems.
However, at first the automatic detection should work well, and if not a specific
chipset can be forced from
/etc/vga/libvga.config .
Because of that,
void vga_setchipset(int chipset )
should probably never be used by applications. If used nevertheless, it should be called
directly before
vga_init (3).
As of now the following values are defined for
chipset:
UNDEFINED
This is the default and specifies autodetection.
VGA
A plain VGA card, not that the SVGA must behave like an ordinary SVGA card then which
will probably mean it is in an ordinary (25x80) textmode.
ET4000
Tseng ET4000/ET4000W32(i/p) cards.
CIRRUS
Cirrus Logic GD542x/3x cards.
TVGA8900
Trident TVGA 8900C/9000 (and possibly also 8800CS/8900A/B) cards.
OAK
Oak Technologies OTI-037/67/77/87 cards.
EGA
An ordinary EGA card. The notes about VGA apply.
S3
ET3000
MACH32
A card (from ATI or not) based on the ATI Mach32 chipset.
GVGA6400
A Genoa(?) GVGA6400 card.
ARK
ARK Logic ARK1000PV/2000PV cards.
ATI
An ATI SVGA (VGA Wonder and friends) card. This does not (necessarily) include
the newer cards (usually called Mach something).
ALI
MACH64
A card using the ATI Mach64 chipset. Support is not complete.
CHIPS
Chips and Technologies chipsets 65525, 65535, 65546, 65548, 65550, and 65554 (usually in laptops).
