Other Parts Discussed in Thread: XIO2001

Dear Sir 

I use XIO2001 to extend 4 PCI slot ,

If I use 4pcs of  PCI 33MHZ LAN card at the same time with XIO2001 and run windows tool for full loading test 

The system will be hang up

If I use 3pcs of PCI 33MHZ LAN card to test ,the system will be workable

So far I had already do below test ,but the result is still fail 

Please kindly help to provide the suggestion to do 4pcs LAN card work at the same time 

1. IDESL and AD16~AD19 connection - correct 

2. INTx routing connection - correct 

3. CLKOUT6 to CLK length is the same with other CLKOUT[5:1] length 

4. Change to 66MHz clock - fail (blue screen) 

Thanks

    Hello,
    It is a combination of all the above registers, those registers work together to control the pre-fetch agent.
    If you want to know which setting causes your system to hang:
    Start with the default settings then adjust the PFA_REQ_CNT_LIMIT register first until you find the setting the gives the best performance. Then using this new setting do the same thing for the PFA_REQ_LENGTH_LIMIT. Keep the caching set to full the entire time.

    I can send you the winrom if you provide an email address.
    Regards
