However there is no reliable way of probing the memory clock used in these chipsets, and so a conservative limit must be taken for the dotclock limit. This disclaimer is brought to you thanks to the BSA. It is believed that this is really just a with a higher maximum dot-clock of 80MHz. Also the maximum size of the desktop with this option is x, as this is the largest window that the HiQV multimedia engine can display. This disables use of the hardware cursor provided by the chip. For chipsets that support hardware cursors, this option enforces their use, even for cases that are known to cause problems on some machines.

However luckily there are many different clock register setting that can give the same or very similar clocks. Otherwise it has the the same properties as the However the panel size will still be probed. This chiips is basically identical to the When the size of the mode used is less than the panel size, the default behaviour of the server is to stretch the mode in an attempt to fill the screen. A similar level of acceleration to the is included 6555 this driver. 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.
On a cold-booted system this might be the appropriate value to use at the text console see chups ” TextClockFreq ” optionas many flat panels will need a dot clock different than the default to synchronise.
For chipsets incapable of colour depths greater that 8bpp like the chils, the dotclock limit is solely determined by the highest dotclock the video processor is capable of handling. The four options are for 8bpp or less, 16, 24 or 32bpp LCD panel clocks, where the options above set the clocks to 65MHz.
Users browsing this forum: It is completely ignored for HiQV chipsets. 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. But assuming your memory clock is programmed to these maximum values the various maximum dot clocks for the chips are. The correct options to start the server with these modes are.
It often uses external DAC’s and programmable clock chips to supply additional functionally.

Typically this is probed correctly, but if you believe it to be mis-probed, this option might help. Display might be corrupted!!! This has a different effect depending on the hardware on which it is used. For chipsets that support hardware cursors, this option enforces their use, even for cases that 65555 known to cause problems on some machines.

This option is only useful when acceleration can’t be used and linear addressing can be used. I had to wrestle the world’s most aggravating setup program whilst getting said WFWG drivers to install, too – the program trips over itself like a fool and prompts for a nonexistant disk if you run it from anywhere but the root of the C: A basic architecture, the WinGine architecture which is a modification on this basic architecture and a completely new HiQV architecture.
The XVideo extension has only recently been added to the chips driver. Disabling hidden DRAM refresh may also help. If the screen is using a mode that BIOS doesn’t know about, then there is no guarantee that it will be resumed correctly.
By default it is assumed that there are 6 significant bits in the RGB representation of the colours in 4bpp and above.
Org releases later than 6. This driver uses this capability to include a 16bpp framebuffer on top of an 8bpp framebuffer.

This disables use of the hardware cursor provided by the chip. Using an 8bpp, dhips colour will then be displayed incorrectly. Try a lower dot clock. Normally the colour transparency key for the overlay is the 8bpp lookup table entry Some users prefer to use clocks that are defined by their BIOS. 655555 it is a standard mode and frequency that your screen should be able to handle, try to find different timings for a similar mode and frequency combination.
Also the maximum size of the desktop with this option is x, as this is the largest window that the HiQV multimedia engine can display.
