In addition the device, screen and layout sections of the ” xorg. The lower half of the screen is not accessible. Display might be corrupted!!! The HiQV series of chips doesn’t need to use additional clock cycles to display higher depths, and so the same modeline can be used at all depths, without needing to divide the clocks. In general the LCD panel clock should be set independently of the modelines supplied.

If the colours seem darker than they should technopogies, perhaps your ramdac is has 8 significant bits. The server itself can correctly detect the chip in the same situation.

Similar to the but has yet higher maximum memory and pixel clocks. However if you do try this option and are willing to debug it, I’d technologirs to hear from you. Using this option the user can override the maximum dot-clock and specify any value they prefer.

The effect of this problem will be that the lower part of the screen will reside in the same memory as the frame accelerator and technoolgies therefore be corrupt. If the user has used the ” UseModeline ” or ” FixPanelSize ” options the panel timings are derived from the mode, which can be different than the panel size.

Note that all of the chips except the rev A are 3.


At this point no testing has been done and it is entirely possible that the ” MMIO option will lockup your machine. Many DSTN screens use frame acceleration to improve the performance of the screen. This information will be invaluable in debugging any problems.

The four options are for 8bpp or less, 16, 24 or 32bpp LCD panel clocks, where the options above set the clocks to 65MHz. This might cause troubles with some applications, and so this option allows the colour transparency key to be set to hechnologies other value.

For some machines the LCD panel size is incorrectly probed from the registers. The current programmable clock will be given as the last clock in the list. However this version of the Chips and Technologies driver has many new features and bug fixes that might make users prefer to use this version.

This can be found from the log file of a working single-head installation. However there are many older machines, particularly those with x screen or larger, that need to reprogram the panel timings.

The HiQV chipsets contain a multimedia engine that allow a 16bpp window to be overlayed on the screen. This is a problem with the video BIOS not knowing about all the funny modes that might be selected. The server doesn’t prevent the user from specifying a mode that will use this memory, it prints a warning on the console.

The whole thing is divided by the bytes per pixel, plus an extra byte if you are using a DSTN. Therefore the server uses a default value of The overlay consumes memory bandwidth, so that the maximum dotclock will be similar to a 24bpp mode. Note that for the this is required as the base address can’t be correctly probed.


This is a more advanced version of the WinGine chip, with specification very similar to the x series of chips. But assuming technologiies memory clock is programmed to these maximum values the various maximum dot clocks for the chips are.

Information for Chips and Technologies Users

However, as the driver does not prevent you from using a mode that will exceed the memory bandwidth of thebut a warning like.

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.

The amount of ram required for the framebuffer will vary depending on the size of the screen, and will reduce the amount of video ram available to the modes. The first two are usually loaded with For CRT’s you can also try to tweak the mode timings; try increasing the second horizontal value somewhat.

Otherwise it has the the same properties as the Hence the server assumes a An 8bpp one and a 16bpp one.
