Can be this chip a sample? I check the codes on the internet and other chips seems to have only B, B2, A Thank you. The DKPCI board (versions A, B, C) includes a number of resistor installation options allowing GPIO pins from the F or B devices to perform. This manual is copyrighted by Chips and Technologies, Inc.

We also thank the many people on the net who have chisp by reporting bugs and extensively testing this server. It is possible that the chip could be misidentified, particular due to interactions with other drivers in the server.

The authors of this software wish to acknowledge the support supplied by Chips and Technologies during the development of this software. It has the same ID and is identified as a when probed. Dual-head display has two effects on the modelines. This option might f6550 be used to reduce the speed of the memory clock to preserve power in modes that don’t need the full speed of the memory to work correctly. If it is a non-standard mode, maybe you need to tweak the timings a bit.

It doesn’t occur f655550 UnixWare 2.

The first two are usually loaded with Firstly, the memory requirements of both heads must fit in the available memory. If you are driving the video ff65550 too fast too high a MemClk you’ll get chiips corruption as the data actually written to the video memory is corrupted by driving the memory too fast. So the driver will attempt to round-up the virtual X dimension to a multiple of 64, but leave the virtual resolution untouched.


However, 8 and 24 bit colour depths seem to work fine.

It is believed that this is really just a with a higher maximum dot-clock of 80MHz. If the colours seem darker than they should be, perhaps your ramdac is has 8 significant bits. A brand-new, unused, unopened and undamaged item in original retail packaging where packaging is applicable. This is useful to see that pixmaps, tiles, etc have been properly cached. It is completely ignored for HiQV chipsets.

This shouldn’t affect higher depths, and is fixable with a switch to the virtual console and back. A basic architecture, the WinGine architecture which is a modification on this basic architecture and a completely new HiQV architecture.

Try a lower dot clock. Using this option the mode can be centered in the screen. Back to v65550 page Return to top. By default the two display share equally the available memory.

Place a shunt jumper on W33 to power down the AD These option individually chipw the features of the XAA acceleration code that the Chips and Technologies driver uses. However these numbers take no account of the extra bandwidth needed for DSTN screens.

This might make certain modes impossible to obtain with a reasonable refresh rate. The and have a 64bit memory bus and thus transfer 8 bytes every clock thus hence the 8while the other HiQV chipsets are 32bit and transfer 4 bytes per clock cycle hence the 4.


So for unexplained problems not addressed above, please try to alter the clock you are using slightly, say in steps of 0.

In fact the timing for the flat panel are dependent on the specification of the panel itself and are independent of the particular mode chosen. You have been warned! 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. 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.

There is the limit of the maximum dotclock the video processor can handle, and there is another limitation of the available memory bandwidth. Redeem your points Conditions for uk nectar points – opens in a new window or tab. 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.

With the chips and later or thethe default is to use the programmable clock for all clocks. Note that all of the chips except the rev A are 3.
