In this case the driver divides the video processors dotclock limitation by the number of bytes per pixel, so that the limitations for the various colour depths are. 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 ” Overlay ” option. The server doesn’t prevent the user from specifying a mode that will use this memory, it prints a warning on the console. So if you have a virtual screen size set to x using a x at 8bpp, you use kB for the mode. A similar level of acceleration to the is included for this driver.

Note that it is overridden by the ” SWcursor ” option. However there are many older machines, particularly those with x screen or larger, that need to reprogram the panel timings. You may notice that the file size of the installer software is much smaller than the file size of your actual driver.

This can result in a reddish tint to 24bpp mode. A technologjes letterbox ” effect with no stretching can be achieved using this option. Author Anx something about chipa. This option will override the detected amount of video memory, and pretend the given amount of memory is present on the card. The following options are of particular interest to the Chips and Technologies driver. If this option is removed form xorg. This option might also be needed to reduce the speed of the memory clock with the ” Overlay ” option.


Chips and Technologies drivers – Chips and Technologies Video Drivers

This can be done by using an external frame buffer, or incorporating the framebuffer at the top of video 6554 depending on the particular implementation. Similar to the but also incorporates “PanelLink” drivers. Try deleting theses options from xorg. Reply to this review Was this review helpful?

The chipset has independent display channels, that can be configured to support independent refresh rates on the flat panel and on the CRT. However this version of the Chips and Technologies driver has many new features and bug fixes that might make tehnologies prefer to use this version.

If you use the ” overlay ” option, then there are actually two framebuffers in the video memory. The effect of this is that the maximum dot clock visible to the user is a half or a third of the value at 8bpp.

For this reason it is recommended to use one of the programs that automatically generate xorg. This option sets the centering and stretching to the BIOS default values.

However it additionally has the ability for mixed 5V tecnnologies 3. From Chips and Technologies: However, some machines appear to have this feature incorrectly setup.


This chip is specially manufactured for Toshiba, and so documentation is not widely available. This option might be used if the default video overlay key causes problems. This problem has been reported under UnixWare 1. Use caution with this option, as driving the video processor beyond its specifications might cause damage.

In this way PseudoColor and TrueColor visuals can be used on the same screen. Note that all of the chips except the rev A are 3. If the colours seem darker than they should be, perhaps your ramdac is has 8 significant bits. This option is only useful when acceleration can’t be used and linear addressing can be used.

XFree86 believes that the 8bpp framebuffer is overlayed on the 16bpp framebuffer.

Enter the e-mail address of the recipient Add your own personal message: By techologies the two display share equally the available memory.

This sets the physical memory base address of the linear framebuffer. The programmable clock makes this option obsolete and so it’s use isn’t recommended.
