problems with bridge in pci bus line
 

My wireless card doesn't work and I think that's it's due to skips in the pci bridges. I need to add the line "pci=assign-busses" to the kernel boot line. However, I'm not sure where to add this. Do I just add it to /boot/grub/menu.lst? and I just add it to the end of the file? I tried to find the bootloader, but could not.

Also, I'm dual booting, reassigning the busses at startup won't screw anything up in windows xp?

Thank you very much for the help ahead of time.

Just edit the corresponding kernel line in /boot/grub/menu.lst and add the pci=assign-busses to the end of it. For example, if should read something like:
kernel /boot/vmlinuz-2.6.17-10-generic root=/dev/sda5 ro quiet splash pci=assign-busses
