Yeah. That's what makes the lspci approach unusable for my purposes.
The approach I want to take is this:
1. Get guaranteed access to the DMI data, either via a /{proc,sys}/dmi or /var/run/dmi initialized at boot time.
2. Develop an exception list of mobos that have ISA slots that don't show up under DMI.
My logic would then be: if the box has PCI, and DMI shows no ISA slots, and the motherboard is not on the exception list, then suppress ISA questions.
This would be a kluge, but it would have the advantage that the exception list is finite and can be expected to stop growing. -- <a href="http://www.tuxedo.org/~esr/">Eric S. Raymond</a>
