Re: Intel Plumas Chipset and 100Mhz PCI cards

Hi/

Both the PCI slots are running the same controller.

The following is the output from the lspci -vv command
for the ethernet controllers

As you can see the capabilites does list PCI-X. I am
currently running BIOS version 1.10 on the
machine.Intel has released a new BIOS 1.12 ;I went
through the release notes and couldnt find anything
which would help.

Any ideas /suggestions.

Please cc: me your replies ; I am not on the Linux
-kernel mailing list.


Thanks
Abhishek
