	34	BUS NUMBERING
	35	-------------
34	36	I2C/SMBus adapters are numbered in the order they are inserted. If you want
35	37	to know what number an adapter has, please make sure module `i2c-proc' is
36	38	inserted, and look at file /proc/bus/i2c. The ISA bus always has the
37	39	symbolic number 9191 (`I' is the ninth letter of the alphabet, `S' the
38		nineteenth and `A' the first). If you want 'any I2C bus', use '-1'
39		(or 65535).
	40	nineteenth and `A' the first). Do not use the ISA Bus number from
	41	/proc/bus/i2c. If you want 'any I2C bus', use '-1' (or 65535).
	42	So to summarize:
	43	-1 Any Bus
	44	0-15 Specific I2C Bus
	45	9191 ISA BUS

	48	ADDRESS NUMBERING

41	50	Each adapter has a number of addresses on I2C/SMBus adapters and/or the

50	59	entering `man modprobe' or `man insmod'.
	60	So to summarize:
	61	0x00 - 0x7f Valid I2C Addresses
	62	0x0000 - 0xffff Valid ISA Bus Addresses
