CHIPS & TECHNOLOGIES 65550 PCI DRIVER DOWNLOAD

The default behaviour is to have both the flat panel and the CRT use the same display channel and thus the same refresh rate. It is possible to turn the linear addressing off with this option. It also includes a fully programmable dot clock and supports all types of flat panels. The overlay consumes memory bandwidth, so that the maximum dotclock will be similar to a 24bpp mode. This may be related to a bug in one of the accelerated functions, or a problem with the BitBLT engine. 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. However there are many differences at a register level.

Firstly, the memory requirements of both heads must fit in the available memory. Additionally, the ” Screen ” option must appear in the device section. This option forces the server to assume that there are 8 significant bits. So with the ” Overlay ” option, using the ” SetMClk ” option to reduce the speed of the memory clock is recommended. It should be noted that the dual channel display options of the technoloies the use of additional memory bandwidth, as each display channel independently accesses the video memory.

This can be done by using an external frame buffer, or incorporating the framebuffer at the top of video ram depending on the particular implementation.

Display might be corrupted!!! The xx MMIO mode technokogies been implemented entirely from the manual as I don’t have the hardware to test it on. We recommend that you try and pick a mode that is similar to a standard VESA mode. It is possible that the chip could be misidentified, particular due to interactions with other drivers in the server. It also includes a fully programmable dot clock and supports all types of flat panels.

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 technologiees are. Typically this will give you some or all of the clocks The HiQV series of chips have three programmable clocks. However to use the dual-head support is slightly more complex. This option is only useful when acceleration can’t be used and linear technolpgies can be used.

This is a debugging option and general users have no need of it. This is useful for the chipset where the base address of the linear framebuffer must be supplied by the user, or at depths 1 and 4bpp. If you find you truly can’t achieve the mode you are after with the default clock limitations, look at the options ” DacSpeed ” and ” SetMClk “.

But assuming your memory clock is programmed to these maximum values the various maximum dot clocks for the chips are. The server will then allow the technologiea to occupy the whole x LCD.

This option can be used in conjunction with the option “UseModeline” to program all the panel timings using the modeline values. This reduces the amount of video ram available to the modes. It also has higher limits on the maximum memory and pixel clocks Max Ram: Chips and Technologies specify that the memory clock used with the multimedia engine running should 655550 lower than that used without. This option sets the centering and stretching to the BIOS default values. In addition to this many graphics operations are technilogies up using a ” pixmap cache “.

However the panel size will still be probed. If this is a problem, a work around is to remove the ” HWcursor ” option. For a complete discussion on the dot clock limitations, see the next section. The XVideo extension has only recently been added to the chips driver. By default it is assumed that there are 6 significant bits in the RGB representation of the colours in 4bpp and above.

However these numbers take no account of the extra bandwidth needed for DSTN screens. This sets the physical memory base address of the linear framebuffer. It might affect some other SVR4 operating systems as well. Hence the maximum dot-clock might need to be limited. This is usually due to a problem with the ” LcdCenter ” option.
