What sets the base address of a card? Is it the card or the PC / BIOS?
All PCI and PCIe cards use PCI enumeration, where the card can be forced to respond by slot during enumeration, and a block of ROM data giving a text string, Vendor ID and device ID and a description of features including register layout. The PCI enumeration then figures out a good fit in the I/O address space and assigns addresses to the card.
So, even if you leave a card in the same slot but add another card, these addresses can get changed.
