Dual refresh rate display can be selected with the ” DualRefresh ” option described above. If 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. Firstly, the memory requirements of both heads must fit in the available memory. You may have chosen to use a CD, and in that case you can simply burn all the files to a CD and transfer them that way. Kinda funny, that’s apparently a relatively early VGA clone chipset yet the machine itself dates to ’96 or so However if you do try this option and are willing to debug it, I’d like to hear from you. It also has higher limits on the maximum memory and pixel clocks Max Ram:

The Chips and Technologies chipsets supported by this driver have one of three basic architectures. Which diagnostic result should I believe, I wonder?

It also includes a fully programmable dot clock and supports all types of flat panels. This option forces the two display channels to be used, giving independent refresh rates. Unfortunately, most if not all require that you use a floppy disk.

Many LCD displays are incapable of using a 24bpp mode. This is a very similar chip to the If you try and go chipe Windows setup and change the driver now, you will find a blank window: This is a more advanced version of the WinGine chip, with specification very similar to the x series of chips.


This serial link allows an LCD screens to be located up to m from the video processor. These option individually disable the features of the XAA acceleration code that the Chips and Technologies driver uses. It doesn’t occur under Chipw 2. This option will override the detected amount of video memory, and pretend the given amount of memory is present on the card. I’ve been trying to restore and I’m having a difficult time with finding video drivers for Win98 in particular – Most of Windows’ built-in CHIPS drivers actually fhips horrible video corruption the second the system tries to display anything that isn’t text mode, the Windows bootsplash or xx16 56550 though the GPU can apparently do xx fine.

Display might be corrupted!!!

For a fhips discussion on the dot clock limitations, see the next section. Answer yes to the prompt that comes up. If you see such display corruption, and you have this warning, your choices are to reduce the refresh rate, colour depth or resolution, or increase the speed of the memory clock with the the ” SetMClk ” option described above. Try a lower dot clock.

You may not reproduce, transmitthis publication without the express written permission of Chips and Technologies, Inc. For this reason the default behaviour of the server is to use the panel timings already installed in the chip. However these numbers take no account of the extra bandwidth needed for DSTN screens.

This option might also be needed to reduce the speed of the 6550 clock with the ” Overlay ” option. However luckily there are many different clock register setting that can give the same or chipe similar clocks.


This chip is basically identical to the Which is the reason for the drop in the dot clock.

This sets the physical memory base address of the linear framebuffer. The flat panel timings are related to the panel size and not the size of the mode specified in xorg.

Similar to the but also incorporates “PanelLink” drivers. Hence I hope that this section will clear up the misunderstandings. The four options are for 8bpp or less, 16, 24 or 32bpp LCD panel chios, where the options above set the clocks to 65MHz.

It often uses external DAC’s and programmable clock chips to supply additional functionally. Many laptops use the programmable clock of the x chips at the console.

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. So with the ” Overlay ” option, using the ” SetMClk ” option to reduce the speed of the memory clock is recommended. Therefore the server uses a default value of
