@ritechnet

1. I don't understand sr-iov enough ,but i google it a while ,i got the necessary conditions to enable sr-iov are os support ,bios support ,device support and driver support. Maybe you ignore one of them??

2. Does this bios dump is made from programmer??

3.You can't see option "Above 4G Decoding" under Advanced >>PCI Subsystem Settings ,right??
