<p>不用示波器，</p><p>对地打PCI的AD及控制信号的二极体值就可以。</p>

会员715

<p>32条AD线是好的，他们测的是CBE_0、PAR、FRAME这三个信号有问题，这片主板的现象板载的显卡检测不到，此主板板载的显卡是从南桥接一组32位PCI　BUS给显示IC的，我在测量的时候只能发现会有一闪波，其它的测量不到，我有图片，但不知道怎么传上来让你看看。</p>

你那板是那出的呀,,显卡不是由北桥控制的吗,你讲的波应该是行场的波行吧

图片呢.

SERVER板，不需要多高的显示，直接走 PCI BUS就可了

会员15

400M的示波器!!!!!!!那么好的工具!!!!!

会员509

应该是Server板，这个是的板载PCI显卡。量测PCI讯号的好坏除CLOCK，RST＃外其它只要量对地二极值就够了，不需要用示波器。
