+PCI BIOS support
+CONFIG_PCI_BIOS
+  If you have enabled PCI bus support above, you probably want to allow
+  Linux to use your PCI BIOS to detect the PCI devices and determine
+  their configuration. Note: some old PCI motherboards have BIOS bugs
+  and may crash if this switch is enabled -- for such motherboards,
+  you should disable PCI BIOS support and use direct PCI access instead.
+  Except for some special cases (embedded systems with no BIOS), you
+  probably should say Y here.
+
+PCI direct access support
+CONFIG_PCI_DIRECT
+  If you don't want to use the PCI BIOS (e.g., because you run some
+  embedded system with no BIOS at all) or Linux says it cannot use
+  your PCI BIOS, you can enable direct PCI hardware here. It might fail
+  if your machine is based on some unusual chipset, but it usually
+  works. If both PCI BIOS and direct PCI access are enabled, the use
+  of BIOS is preferred. If unsure, say Y.

+  operation at up to 10MB/s.  On machines where the SCSI bus
+  controlled by the MESH can have external devices connected, it is
