3C90x - Why does my HP VA PC hang at POST during memory check?

Question: After installing a 3C90X NIC in my HP VA machine and attached to the network, if I perform a warm boot, the machine will hang at POST during memory check.

Answer: The PC only hangs if the NIC is installed onto a live network. Since HP implements a PCI RESET a bit differently than how the 3C90X detects this signal, the NIC is still active at the time of reboot (i.e. it is not aware of the warm boot command Ctrl Alt Del). Please contact HP for an updated BIOS that resolves this issue.
