Well, here's why.
Let's say I take out the PCI card and put the AGP card in. I reboot
(into text only mode, of course) and spend some time trying to set up X.
I give up, and want to go back to the PCI card to run Netscape, look for
more info, maybe download some new files. I have to open the box, take
out the AGP card and put the PCI card back in.
Now, once I've found out some more info, or downloaded some files, I
need to open the box, take out the PCI card and put back the AGP card.
It would be much simpler if I could keep both cards in there for a few
days. I would be able to boot the machine in text mode, change a
parameter so as to select initialisation of the AGP card, reboot and try
X. If it doesn't work, I change the parameter so as to select the PCI
card (which works), and do some more research.
Now, I have read somewhere, that you can set the order of initialisation
of PCI cards. I think that this is the mechanism used to set, for
instance, which NIC is initialised as being eth0 and which as eth1 in a
I hope that a similar mechanism can be used to select a PCI card or an
AGP card to the exclusion of the other... Or perhaps, if the BIOS
automatically enables the AGP card whenever present, simply disable the
AGP card in the boot sequence, so that the OS is forced to use the PCI
I hop also that my problem is sufficiently well defined, now, and that
somebody will have run into a similar problem. No schadefreude intended,
of course ;-) since I am hoping for a solution!
