CHIPS AND TECHNOLOGIES 65550 DRIVER

This is a problem with the video BIOS not knowing about all the funny modes that might be selected. However there are many differences at a register level. This can result in a reddish tint to 24bpp mode. The problem here is that the flat panel needs timings that are related to the panel size, and not the mode size. Alternatively the user can use the ” TextClockFreq ” option described above to select a different clock for the text console.

Hence the maximum dot-clock might need to be limited. Therefore the server uses a default value of For the chips either using the WinGine or basic architectures, the chips generates a number of fixed clocks internally. As anf additional note, the boot splash has a bit of text referring to the video chipset that might tell us a little more: That would explain the corruption issue.

tevhnologies 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. The amount of ram required for the framebuffer will vary depending on the size of the screen, and will reduce the amount of video ram available to the modes. It should be noted that the dual channel display options of the require the use of additional memory bandwidth, as technologiies display channel independently accesses the video memory.

Really like the form factor! This option might be used if the default video overlay key causes problems.

However to use the dual-head support is slightly more complex. The ct supports dual-head display. The ” 665550 ” can be used to force the modeline values into the panel size registers. It is completely ignored for HiQV chipsets. However use caution with these options, because there is no guarantee that driving the video processor beyond it capabilities won’t cause damage. Techbologies is possible to force the server to identify a particular chip with this option.

Many potential programmable clock register setting are unstable. If you exceed the maximum set by the memory clock, you’ll get corruption on the screen during graphics operations, as you will be starving the HW BitBlt engine of clock cycles.

This is correct for most modes, but can cause some problems. Note that the ” -bpp ” option has been removed and replaced with a ” -depth ” and ” -fbbpp ” option yechnologies of the confusion between the depth and number of bits per pixel used to represent to framebuffer and the pixmaps in the screens memory.

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 cause horrible video corruption the second the system tries to display anything that isn’t text mode, the Windows bootsplash or xx16 colors though the GPU can apparently do xx fine.

However some video ram, particularly EDO, might not be fast enough to handle this, resulting in drawing errors on the screen. If you get pixel error with this option try using the ” SetMClk ” option to slow the memory clock.

Also, a photo of the machine itself for anyone who’s curious!

The XVideo extension has only recently been added to the chips driver. Try this if the cursor seems to have problems. I’ll technnologies this post once I have. The driver is capable of driving both a CRT and a flat chios display. For technplogies complete discussion on the dot clock limitations, see the next section.

A general problem with the server that can manifested in many way such as drawing errors, wavy screens, etc is related to the programmable clock. Further to this some of the XAA acceleration requires that the display pitch is a multiple of 64 pixels. VBEMP is more or less my last resort for if I can’t find drivers specifically for the 82c, but won’t it result in degraded performance vs.

That is from 0 to for 8bit depth, 0 to 32, for 15bit depth, etc. But assuming your memory clock is programmed to these maximum values the various maximum dot clocks for the chips are. The overlay consumes memory bandwidth, so that the maximum dotclock will be similar to a 24bpp mode. 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.
