23Device-specific notes
24---------------------
25
26The SC1100 WRAP boards are known to use base addresses 0x810 and 0x820.
27If the scx200_acb driver is built into the kernel, add the following
28parameter to your boot command line:
29 scx200_acb.base=0x810,0x820
30If the scx200_acb driver is built as a module, add the following line to
31the file /etc/modprobe.conf instead:
32 options scx200_acb base=0x810,0x820
