RE: [ixp1200] GigaMAC diagnostic problems...
What microcode are you running to run this test? I will try to reproduce the problem here. --Dirk

Has anyone tried to use the diagnostics w/ the GigaMACs---we set it up and both internal and external loopback modes fail. We have the MAC enabled w/ jumper J34 and we get the status lights on both the ports when we loop a cable between them but the IXbus tx/rx tests fail---the microcode should send packets and recv them but it doesn't. I'm wondering if this is a hardware problem or a diagnostic program problem. I think it is the latter because if I run my own diagnostic program, I can get the GigaMAC's receive counter to increase when I send it packets (even though it doesnt appear to assert the rxrdy flag when the IX bus polls it). Any guidance?

Im talking about the diagnostics test from Intel---it comes w/ the system. Unless you've removed the diagnostics from the flashROM you should be able to set jumpers 12 & 26 both to 2-3 and restart it. But, if you really want the microcode, its in the BoardSupport/Diagnostics directory of the installation. Austen McDonald austen@cc.gatech.edu God does not care about our mathematical difficulties.
