- JP6 is reserved for future AMD K6 processors. Simply leave JP6 OPEN for all existing Intel,
Cyrix, AMD K5 and AMD K6 processors.
- This motherboard is compatible with Cyrix 6x86 CPU, which must be Revision 2.7 or newer.
Please contact your CPU supplier for details on identification of Cyrix 6x86 CPU revisions
- This motherboard can be run with Cyrix 6x86-P200+ CPU specifications of all add on cards.
If system does not behave reliably at 75MHz Bus Clock , you should set the Bus Clock to
50MHz (JP3 set "2-3", JP4 set "2-3", JP5 set "2-3").
- JP8 set "1-2" means Synchronous CPU Clock/PCI Clock. JP8 set "2-3" means ASynchronous
CPU Clock/PCI Clock (always 32MHz).
- * = Default setting.
