^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) * base: up to 4 ints
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) Base addresses for the ACCESS.bus controllers on SCx200 and SC1100 devices
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) By default the driver uses two base addresses 0x820 and 0x840.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) If you want only one base address, specify the second as 0 so as to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) override this default.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) The SC1100 WRAP boards are known to use base addresses 0x810 and 0x820.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) If the scx200_acb driver is built into the kernel, add the following
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30) parameter to your boot command line::
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31)

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34) If the scx200_acb driver is built as a module, add the following line to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35) a configuration file in /etc/modprobe.d/ instead::
