- * With respect to clocks, Mach64's are entirely different animals.

- * The oldest Mach64's use one of the non-programmable clock generators

- * All other Mach64 adapters use a programmable clock generator. BIOS
- * initialisation programmes an initial set of frequencies. Two of these are
- * reserved to allow for the setting of modes that do not use a frequency from
- * this initial set. One of these reserved slots is used by the BIOS mode set
- * routine, the other by the particular accelerated driver used (MS-Windows,
- * AutoCAD, etc.). The slots reserved in this way are dependent on the
- * particular clock generator used by the adapter.
- *
- * If the driver does not support the adapter's clock generator, it will try to
