一些老主板的关健频率和电压

1.基本电压含:
             vcc3: 3.3v
             vtt: 1.5v
             vcc25: 2.5v
             vcc333: 3.3v
             vcc: 5v
             vcore: cpu之工作电压(是cpu or电压治具而定)
             power_ok or power_good: 3.3v
             cpu之参考电压: ex: vgtl:1v
可power on时先量测基本电压via socket462系列
2.各个rst含:
             pcirst :由hi准位到low准位(5v or 3v)
             agprst :由hi准位到low准位(5v or 3v)
             cpurst:可分(1)586 :由low准位到hi准位(3v)
                                   (2)686 :由hi准位到low准位(1.5v)
                                   (3)socket 462系列:由hi准位到low准位(1.7v)
                                   (4)socket 478系列:由hi准位到low准位(1.5v)
             creset :由hi准位到low准位( 3.3v)
             rst_bt :由hi准位到low准位(3v)
             ide_rst :由hi准位到low准位(5v)
3.各项clk含:
               (1)isa: 14.318mhz(osc由clkgen来)
                             8mhz(bclk由南桥产生)
             (2)pci: 33mhz
             (3)agp: 1x: 33mhz
                             2x: 66mhz
                             4x: 133mhz(uagp有132pin)
             (4)dimm: 66mhz ,100mhz ,133mhz.
             (5)ddr: 100mhz,133mhz,166mhz,200mhz.
             (6)cpu: 66mhz,100mhz ,133mhz.
             (7)北桥: 66mhz,100mhz,133mhz,200mhz.
             (南桥: 14.318mhz.
                             48mhz.
                             33mhz.
             (9)i/o: 48mhz or 24mhz
intel 478系列:
               (1)pci: 33mhz
             (2)agp: 4x: 133mhz(uagp有132pin)
             (3)dimm: 100mhz,133mhz
             (4)cpu: 100mhz,133mhz
             (5)北桥: 66mhz ,100mhz ,133mhz
             (5)南桥: 14.318mhz
                             48mhz
                             33mhz
                             66mhz
             (6)lpc i/o: 33mhz,24mhz,48mhz.
                       *以上皆正常后才上cpu and dimm测试是否开机
