RHAS 4 Not Detecting NIC
 

Hi,

We just purchased an HP Proliant DL585 G2 server which has two NC371i Multifunction Gigabit Network Adapters (other specs: four dual core 64 bit 2.6Ghz AMD Opteron processors, 8G Memory, 2 73G drives). I just installed Redhat AS 4 (AMD64/Intel EM64T version) which went smoothly but it didn't detect the network adapters. I downloaded and installed the drivers from HP's site but still no luck. I can't figure out why it won't detect the network adapters. If anyone has come across this problem or has any suggestions, it'd be much appreciated.

Thanks.

Which drivers from HP did you download, the name and/or download link would be helpful.
Did the drivers have and installation or readme guide or file, if yes then try some reading.

Thanks...I found that it was a problem with PCI probing. According to redhat:

"During PCI probing, Red Hat Enterprise Linux 4 attempts to use information obtained from MCFG (memory-mapped PCI config space ACPI table). On AMD systems, there are buses where this type of access does not work and the kernel cannot parse the MCFG table.

"As a work around, the kernel needs to be informed not to use MCFG on AMD based systems. Use the workaround "pci=conf1" or "pci=nommconf" on the kernel boot line in /etc/grub.conf to tell the kernel to use PCI Conf1 type access instead of MCFG-based access."

Thanks for the update and link to the article, it is always nice to see how an issue can be solved.
