ISA 14.318MHz Clock

Common Options : Enabled, Disabled

Quick Review

This BIOS feature allows you to overclock the ISA bus using the reference clock generator speed of 14.318MHz. This greatly improves the ISA bus speed by running the bus 72% faster than normal. At this clock speed, 8-bit cards will have a bandwidth of 7.16MB/s while 16-bit cards will have a bandwidth of 14.32MB/s.

In most cases, it is recommended that you enable this feature to give the ISA bus a performance boost. Of course, this is only useful if you have ISA devices in your system. Otherwise, this feature is redundant.

Please note that while newer ISA cards are capable of running at this 'out-of-spec' speed, older ones may not work properly at this speed. Therefore, if your ISA card fails to function properly, disable this feature.
