This DOS program and its source is included in the svgalib distribu. You may create a et4000.regs on your own with the tseng3.exe program. See the et4000/ subdirectory of the svgalib distribution for examples.ģ. The actual scanner/parser will handle the following entries:Įnable MODE1 using MODE2 registers, eg. If you haveĪ working et4000.regs for your system just copy this file to /etc/vga/libvga.et4000 or link /etc/vga/libvga.et4000 to your The dynamic configuration will be read from /etc/vga/libvga.et4000 which is an ASCII file (see Makefile.cfg for exact naming). Start up faster but might fail on other machines.Ĭompiling the svgalib(7) with DYNAMIC defined (see Makefile.cfg) will set up dynamic register loading. If you use hard linked values, the binary will be smaller and The svgalib(7) may use hard linked or dynamical linked register values. If svgalib(7) fails on your machine or you haveĪ HiColor dac, you need to configure your svgalib(7).

HOW TO CONFIGURE SVGALIB svgalib(7) has a somewhat 'standard' registers set that may work with modern ET4000 cards. The required register values are card dependent.Ģ. Since the video timing is based on the pixel frequency,
Quency synthesizer and provide the following pixel frequencies (in MHz):ĥ0.350 56.644 65.0 72.0 80.0 89.8 63.0 75.0Ĭhecking older ET4000 cards we found a wide spread range of available frequencies. VRAM equipped cards, please tell us about.īy now we found is no reliable way to detect the memory organisation/ timing and the DAC type/capabilities. Svgalib(7) will check the available video memory during startup. There are three important points to be kept in mind:Ī.) amount of available, the organisation and timing of video memory the vgadoc2.zip) and all graphics functions can be used the same way on differentĬards (including the ET4000/W32 based ones).
The Chipset is well documented (by Tseng Labs and eg. Using dynamic loading with other cardsīasically all ET4000 cards are equal, some are even more equal.
