Two, as I recall, `mode 1' and `mode 2.' Mode 2 is the newer and
better way to do it.

If you can compile a new kernel, you can force a configuration
mode. From src/sys/arch/i386/pci/pci_machdep.c:

 * The configuration method can be hard-coded in the config file by
 * using `options PCI_CONF_MODE=N', where `N' is the configuration mode
 * as defined section 3.6.4.1, `Generating Configuration Cycles'.
