.SH OPTIONS 
.TP 5
.B \-i
# interpret the data on the EEPROM and display it as a set of fields.
.TP 5
.B \-f
# Use \fIdevice\fR instead of \fI/dev/i2c-1\fR.
.TP 5
.B \-a
# Use \fIslave_address\fR instead of \fI0x50\fR.
.TP 5
.B \-n
# Do not send the page number when addressing the memory on the EEPROM. Some
smaller EEPROM chips aren't organized into pages and get confused if a page
number is sent with the memory address. Use this when reading EDID.
.SH EXAMPLES
.TP 20
.B eepromread -i
# display the contents of the EEPROM as a list of label:value pairs.
.TP 20
.B eepromread
# display the first 256 bytes of the EEPROM in HEX and ASCII.
.TP 20
.B eepromread -f /dev/i2c-3 -a 0x54
# display the first 256 bytes of the EEPROM on I2C bus 3, slave address 0x54.
.TP 20
.B eepromread -f /dev/i2c-3 -n
# read the EDID info from the display on I2C bus 3 on the BeagleBoard-xM.
.TP 20
.B eepromread -f /dev/eepromb1s50 -i
# access the EEPROM through the /dev/eeprom interface once the
cat24c256 driver has been started.
.SH DESCRIPTION
.PP
\fIeepromread\fR is a simple tool for viewing the contents of an EEPROM.
For EEPROM data that is in a specific format that this program knows how to
detect, \fIeepromread\fR can properly format each of the fields and display
the information via the \fI-i\fR command line option.
.SH NOTES
If the \fIcat24c256\fR driver has claimed the EEPROM device that this
program is attempting to read from, then you must access it through
the /dev/eeprom interface rather than the /dev/i2c interface.
