+.Sh DESCRIPTION
+.Ox
+provides machine-independent bus support and drivers for CardBus devices.
+.Pp
+The flags are used with cardslot definition.
+The lowest order (right-most)
+bit of defines the PC Card attach sequence at
+boot-time.
+When the bit is set, a PC Card in the slot is probed and
+attached immediately.
+However, the PC Card is probed after kernel thread wakes up.
+If a PC Card is used as a boot device (e.g., CF
+card or network card), you should set this bit to 1.
+.Sh SUPPORTED DEVICES
+.Ox
+includes the following machine-independent CardBus
+drivers, sorted by function and driver name:
