Chips and Technologies specify that the memory clock used with the multimedia engine running should be lower than that used without. Also for non PCI machines specifying this force the linear base address to be this value, reprogramming the video processor to suit. Alternatively the user can use the ” TextClockFreq ” option described above to select a different clock for the text console. A ” letterbox ” effect with no stretching can be achieved using this option. The total memory requirements in this mode of operation is therefore similar to a 24bpp mode. This has been reported on some configurations. So for unexplained problems not addressed above, please try to alter the clock you are using slightly, say in steps of 0.

If the colours seem darker than they should be, perhaps your ramdac is has 8 significant bits. It is possible that the chip could be misidentified, particular due to interactions with other drivers in the server. Option “NoAccel” This option will disable the use of any accelerated functions. The HiQV series of chips have three programmable clocks. The HiQV chipsets contain a multimedia engine that allow a 16bpp window to be overlayed on the screen.

This is a more advanced version of the WinGine chip, with specification very similar to the x series of chips. This can result in a reddish tint to 24bpp mode. Some users prefer to use clocks that are defined by their BIOS. There are therefore a wide variety of possible forms for all options.


This shouldn’t affect higher depths, and is fixable with a switch to the virtual console and back. This may be related to a bug in one of the accelerated functions, or a problem with the BitBLT engine. It is believed that this is really just a technologes a higher maximum dot-clock of 80MHz.

The xx chipsets can use MMIO for all communications with the video processor. The ” FixPanelSize ” can be used to force the modeline values into the panel size registers. For instance, the line. This is a driver limitation that might be relaxed in the future.

If you find you truly can’t achieve the mode you are after with the default clock limitations, look at the options ” DacSpeed ” and ” SetMClk “. For CRT’s you can also try to tweak the mode timings; try increasing the second horizontal value somewhat.

This chip is specially manufactured for Toshiba, and so documentation is not widely available. Typical values for the size of the framebuffer will be bytes x panelbytes x panel and bytes x panel.

It also has higher limits on the maximum memory dhips pixel clocks Max Ram: For other screen drawing related problems, try the ” NoAccel ” or one of the XAA acceleration options discussed above. Hence I hope that this section will clear up the misunderstandings.

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. The differentiation between the models is seen not only in their capacities but also in their speed performance, the index of which will be uncovered below. So with the ” Overlay ” option, using the ” SetMClk ” option to reduce the speed of the memory clock is recommended.

In its current form, X can not take advantage of this second display channel. So using this option on a xx chipset forces them to use MMIO for tecbnologies communications.

By default it is assumed that there are 6 significant nad in the RGB representation of the colours in 4bpp and above. Many laptops use the programmable clock of the x chips at the console. Search for drivers by ID or device name Known devices: This is useful to see that pixmaps, tiles, etc have been properly cached.

The authors of this software wish to acknowledge the support supplied by Chips and Technologies during the development of this yechnologies. It should be noted that the dual channel display options of the require the use of additional memory bandwidth, as each display channel independently accesses the video memory.

Use caution as excess heat generated by the video processor if its specifications are exceeded might cause damage.
