[LinuxBIOS] Bios & PCI

[Art Fore]

Apparently, the PCI bus is setup during booth with the bios. We have a 
problem with this. We have a system, dual booth Suse Linux and WinXP. It 
is connected via a "Stargen" chip which is actually a serial PCI bridge. 
This controls an external instrument where each card is a PCI instrument 
connected via andother "Stargen" chip.  If we shut down the instrument 
system, and change a card, and turn it back on, we then have to rebooth 
the computer to get it to re-instanciate the PCI bus and recognize the 
new card.

Is it possible with OpenBios or LinuxBios to be able to perform this 
function from the operating system without having to do a reboot?

Please note I am not a bios guru.

Did you try the latest kernel with hot plug pci support?

Have not tried that yet. Will try it. Hopefully it works. Will be good 
excuse not to use Windows for the system, altlhough the application is 
written in .net so we can use in in Llnux with Mono.

I think, as Yh Lu mentioned, the OS should be doing that job, not the 
BIOS. Have you looked at hot plug support at this point?

thanks
