Note: ATI mach64 based boards use several RAMDAC types, video memory types ( VRAM/DRAM ), clock generator chips etc. That's why the supported mode list is dependent on individual board configuration. 

Smart display modes managment

Each ATI mach64 based board has ROM-coded table which describes highest supported resolutions, color depths, refresh rates and dot clock frequency values for each individual board. ATImach64 display driver makes supported mode list depended on this table. 

Advanced cunfiguration options ( Expert Inspector )

ATImach64 Display Adapter Device Driver has extended Select Mode Panel for Configure.app. 
	Part User  includes standard Select Panel means.
	Part Expert  is designed for experienced users who wish to custom-tailor their card configuration for best possible performance.
	This panel is used for:
1.  Changing refresh rate for current resolution/color depth 'on the fly'-
without system rebooting.
2.  Tuning screen adjustments ( the screen centering, position, refresh rate and line frequency on one mode, keeping all other modes unchanged ). Display modes may be configured to use the best resolution and refresh rate your monitor can support.
3.  Changing current mode ( resolution, color depth and refresh rate ) via WindowServer only rebooting (  'exit' command in Login Panel ).

Installing the Device Driver
