Hi B-O,

Thanks for this feedback/tip. Will make sure we check this out as well.

Much appreciated.

Gerard

Hi Gerard,

In case you have problem with a second NIC in the PCI expansion bus using
the silver jaw lure, the problem is the violation of PCI timing as the
PLTRST# signal is not used to reset the NIC. They use the PWROK signal to
reset the NIC and on a reboot the PWROK remains high. In the case of full
reset from PCI reset register the PWROK gets initial low and then high, but
violates the PCI bus reset protocol as the RESET# signal should remain low
for at least 100 mS after power (PWROK) is stable.

Best regards,

B-O
