+The SMBus Driver
+----------------
+
+The SMBus driver allows up to 4 SMBus devices to be configured in the
+system.  By default, the driver will register any SMBus interfaces it finds
+in the I2C address range of 0x20 to 0x4f on any adapter.  You can change this
+at module load time (for a module) with:
+
+  modprobe ipmi_smb.o
+	addr=<adapter1>,<i2caddr1>[,<adapter2>,<i2caddr2>[,...]]
+	dbg=<flags1>,<flags2>...
+	[defaultprobe=1] [dbg_probe=1]
+
+The addresses are specified in pairs, the first is the adapter ID and the
+second is the I2C address on that adapter.
+
+The debug flags are bit flags for each BMC found, they are:
+IPMI messages: 1, driver state: 2, timing: 4, I2C probe: 8
+
+Setting smb_defaultprobe to zero disabled the default probing of SMBus
+interfaces at address range 0x20 to 0x4f.  This means that only the
+BMCs specified on the smb_addr line will be detected.
+
+Setting smb_dbg_probe to 1 will enable debugging of the probing and
+detection process for BMCs on the SMBusses.
+
+Discovering the IPMI compliant BMC on the SMBus can cause devices
+on the I2C bus to fail. The SMBus driver writes a "Get Device ID" IPMI
+message as a block write to the I2C bus and waits for a response.
+This action can be detrimental to some I2C devices. It is highly recommended
+that the known I2c address be given to the SMBus driver in the smb_addr
+parameter. The default address range will not be used when a smb_addr
+parameter is provided.
+
+When compiled into the kernel, the addresses can be specified on the
+kernel command line as:
+
+  ipmb_smb.addr=<adapter1>,<i2caddr1>[,<adapter2>,<i2caddr2>[,...]]
+	ipmi_smb.dbg=<flags1>,<flags2>...
+	ipmi_smb.defaultprobe=0 ipmi_smb.dbg_probe=1
+
+These are the same options as on the module command line.
+
+Note that you might need some I2C changes if CONFIG_IPMI_PANIC_EVENT
+is enabled along with this, so the I2C driver knows to run to
+completion during sending a panic event.
