vga_setchipsetandfeatures(3) Svgalib User Manual vga_setchipsetandfeatures(3) NAME
vga_setchipsetandfeatures - force chipset and optional parameters SYNOPSIS
#include <vga.h> void vga_setchipsetandfeatures(int chipset, int par1, int par2); DESCRIPTION
Force chipset, and optional parameters like the exact chipset type and the amount of video memory installed. This function works similar to vga_setchipset(3) and allows the same values for chipset. In addition you can pass additional parameters to the setup routine whose mean- ing heavily depend on the driver. You should only use this for debugging and if you know what you do, which is why we do not document any- thing more here. SEE ALSO

This manual page was edited by Michael Weller <eowmob@exp-math.uni-essen.de>. The exact source of the referenced function as well as of the original documentation is unknown. It is very likely that both are at least to some extent are due to Harm Hanemaayer <H.Hanemaayer@inter.nl.net>. Occasionally this might be wrong. I hereby asked to be excused by the original author and will happily accept any additions or corrections to this first version of the svgalib manual.
