The setting are: Default , 66/33, 75/37, 83/41, 100/33, 103/34, 112/37, 124/41, 105/35, 110/36, 115/38, 120/40, 133/44. When the setting is :"default" the CPU HOST Clock will depend on the setting of JP9. If JP9 are set to 66MHz only have the choice of 66/33, 75/37, 83/41 on screen. If the JP9 are setting at 100MHz, then you can have 100/33, 103/34, 112/37, 124/41, 105/35, 110/36, 115/38, 120/40, 133/44. *Please turn off system power if the screen does not have any display after change of the setting. Then press and hold down " INS " key, and turn on system power again (release " INS " key till the screen has display) to reset correct frequency of CPU HOST clock. · DRAM Clock: In this item you have the choice : Host CLK , HCLK ­33M. We recommend the Max. 3-4 POWER MANAGEMENT SETUP 18 The Power Management Setup allows you to configure you system to most effectively save energy while operating in a manner consistent with your own style of computer use.

Disables all four modes Minimum power management. Standby Mode = 1 hr. , Suspend Mode = 1 hr. , and HDD Power Down = 15 min. Power Saving Maximum power management -- ONLY AVAILABLE FOR SL CPU'S. Doze Mode = 1 min. , Standby Mode = 1 min. , Suspend Mode = 1 min. , and HDD Power Down = 1 min. User Defined Allows you to set each mode individually. When not disabled, each of the ranges are from 1 min. except for HDD Power Down which ranges from 1 min. and disable. There are four selections for Power Management, three of which have fixed mode settings. PM Control APM: When enabled, an Advanced Power Management device will be activated to enhance the Max. Power Saving mode and stop the CPU internal clock. Power Saving is not enabled, this will be preset to No. [. . . ] A¡G IF your motherboard embedded Audio chip, you can set JP4 1-2 closed to disable onboard sound controller. Q¡G What can I do after setting higher frequency in "CPU Host / PCI CLK" the system hang up (do no have display)?A¡G Press and hold down "INS" key then turn on computer power (release "INS" key till the screen has display). Get into BIOS setup, and reset correct frequency. [. . . ]
