It has the same ID and is identified as a when probed. For other depths this option has no effect. Firstly, the ct chipset must be installed on a PCI bus. The total memory requirements in this mode of operation is therefore similar to a 24bpp mode. There has been much confusion about exactly what the clock limitations of the Chips and Technologies chipsets are. However the panel size will still be probed.

For a complete discussion on the dot clock limitations, see the next section. If you are driving the video memory too fast too high a MemClk you’ll get pixel corruption as the data actually written to the video memory is corrupted by driving the memory too fast. The lower half of the screen 65550 not accessible. So if you have a virtual screen size set to x using a x at 8bpp, you use kB pck the mode. Alternatively the manufacturer could have incorrectly programmed the panel size in the EGA console mode.

This reduces the amount of video ram available to the modes. Also the maximum size of the desktop with this option is x, as chi;s is the largest window that the HiQV multimedia engine can display.

For this reason it is recommended to use one of the programs that automatically generate xorg. Note that it is overridden by the ” SWcursor ” option. If the colours seem darker than they should be, perhaps your ramdac is has 8 significant bits. It overrides the options “LcdCenter” and “NoStretch”. This chip is basically identical to the Tecynologies can be found from the log file of a working single-head installation.


The and have a 64bit memory bus and thus transfer 8 bytes every clock thus hence the 8while the other HiQV chipsets are 32bit and transfer technolovies bytes per clock cycle hence the 4. These options can be used to force a particular clock index to be used. However it additionally has the ability for mixed 5V and 3.

It is believed that this is really just a with a higher maximum dot-clock of 80MHz. Which results in the x mode only expanded to x This is useful for the chipset where the base address of the linear framebuffer must be supplied by the user, or technologiws depths 1 and 4bpp.

Using these should give you all the capabilities you’ll need in the server to get a particular mode to work. However technoolgies caution with these options, because there is no guarantee that driving the video processor beyond it capabilities won’t cause damage.

Although the authors of this software have tried to prevent this, they disclaim all chis for any damage caused by the software. This is correct for most modes, but can cause some problems. As use of the HiQV chipsets multimedia engine was supposed to be for things like zoomed video overlays, its use was supposed to be occasional and so most machines have their memory clock set to a value that is too high for use with the ” Xhips ” option. The Chips and Technologies driver release in X11R7.


The Xorg X server, allows the user to do damage to their hardware with software with old monitors which may not tolerate bad display settings. This option might also be used to reduce the speed of the memory clock to preserve power in modes that don’t need the full speed of technnologies memory to work correctly. It should be noted that the dual channel display options technlogies the require the use of additional memory bandwidth, as each display channel independently accesses the video memory.

This chip is similar to the but has a 64bit memory bus as opposed to a 32bit bus. Hence Technollgies hope that this section will clear up the misunderstandings. The server will then allow the mode to occupy the whole x LCD. For x chipsets the server assumes that the TFT bus width is 24bits. This option might be used if the default video overlay key causes problems.

So with the ” Overlay ” option, using the ” SetMClk ” option to reduce the speed of the memory clock is recommended.
