## 4. Known Problems and Bug Reports

There are several known problems with the current version of the Mach64 X server. They include:

- Screen blanking in 16bpp and 32bpp modes on certain Mach64 CT cards does not work.
- In doublescan modes, only the top half of the hardware cursor is displayed. The hardware cursor works fine in all other modes.
- Text may not be displayed correctly in certain programs.
- Some RAMDACs are incorrectly reported by the BIOS. This can be handled by explicitly specifying the RAMDAC in the XF86Config file. This should no longer be a problem.
- ISA cards with more than 12Mb of main memory cannot use the server due to the requirement of a video memory aperture. This a major project.

If you are experiencing problems, first check to make sure that you have the very latest available release (including beta releases). ATI releases new cards throughout the year. Each of these new cards require additional programming to support the new Mach64 chips, RAMDACs and clock chips that appear on them. The most recent release is most likely to support your video card.

Second, please check the RELNOTES and README files (as well as the other documentation available with the release). Third, make sure you do not have any Ramdac, ClockChip or Clocks lines in your XF86Config file (all of these are automatically detected by the Mach64 X server).

If you are still experiencing problems, please send e-mail to XFree86@XFree86.org or post to the comp.windows.x.i386unix newsgroup.

Please do NOT send e-mail to me since the developers who answer e-mail sent to XFree86@XFree86.org are better able to answer most questions and I would like to spend my minimal free time working on new enhancements to the X server. Thanks!
