This option might be used if the default video overlay key causes problems. If it is a non-standard mode, maybe you need to tweak the timings a bit. Option “NoAccel” This option will disable the use of any accelerated functions. Chips and Technologies specify that the memory clock used with the multimedia engine running should be lower than that used without. You are probably using a dot clock that is too high or too low ; it is also possible that there is interference with a close MCLK. Dual refresh rate display can be selected with the ” DualRefresh ” option described above. Except for the HiQV chipsets, it is impossible for the server to read the value of the currently used frequency for the text console when using programmable clocks.

Firstly, the memory requirements of both heads must fit in the available memory. When the chipset is capable of linear addressing and it has been turned off by default, this option can be used to turn it back on.

The server will then allow the mode to occupy the whole x LCD. Using an 8bpp, the colour will then be displayed incorrectly. Firstly, the ct chipset must be installed on a Yech bus. Many DSTN screens use frame acceleration to improve the performance of the screen. Which is the reason for the drop in the dot clock.

Did this card even have an ISA flavor? This problem has been reported under UnixWare 1. 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: For the HiQV series of chips, the memory clock can be successfully probed.

A basic architecture, the WinGine architecture which is a modification on this basic architecture and a completely new HiQV architecture. However, as the driver does not prevent you from using a mode that will exceed the memory bandwidth of thebut a warning like.

Note that all 65505 the chips except the rev A are 3. Many LCD displays are incapable of using a 24bpp mode. As use of the HiQV chipsets multimedia engine was supposed to be for things like zoomed video overlays, its use was supposed tefh be occasional and so most machines have their memory clock set to a value that is too high for use with the ” Overlay ” option.

It also reduces the effect of cursor flashing during graphics operations. This may be related to a bug in one of the accelerated functions, or a problem with the BitBLT tch. This might make certain modes impossible to obtain with a reasonable refresh rate.

Do you have any means of determining how much video memory your machine have? In this way the expensive operation of reading back to contents of the screen is never performed and the performance is improved. At this point no testing has been done and it is entirely possible that the ” MMIO option will lockup your machine.

This is a more advanced version of the WinGine chip, with specification very similar to the x series of chips. Really I more just wanna get video drivers that aren’t generic ones loaded tbh – the 82C seems to only have 1MB VRAM from what I can tell so I’m not gonna be doing anything especially intensive on this 665550 but that’s not really what it was designed for.


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. Would anyone happen to 665550 any advice or leads on the matter? A sample of an incomplete ” xorg. The server doesn’t prevent the user from specifying a mode that will use this memory, it prints a warning on the console.

The forms given below are the preferred forms. Options related to drivers can be present in the Cuips, Device and Monitor sections and the Display subsections.

The XVideo extension has only recently been added to the chips driver. However these numbers take no account of the extra bandwidth needed for DSTN screens.

The Xserver assumes that the framebuffer, if used, will be at the top of video ram.

Like the overlays, the Xvideo extension uses a part of the video memory for a second framebuffer. This shouldn’t affect teh depths, and is fixable with a switch to the virtual console and back.
