SDRAM Frequency Setting - JA25 & JP9
HOT-591P support 100MHz external frequency AMD-K6 3D, and which allows the user to use
66MHz normal SDRAM DIMM or 100MHz PC/100 SDRAM DIMM. Jumpers JA25 and JP9
are used to set SDRAM frequency which synchronous with System Clock (CPU External Clock)
or synchronous with AGP External Clock.
This feature allows the user to use normal SDRAM with AMD-K6 3D processor.
