+.TP
+.B "\-a, \-\-all"
+Dump all known I/O Controller Hub (ICH) southbridge, Intel(R) northbridge and Intel(R) Core CPU MSRs.
+.TP
+.B "\-g, \-\-gpio"
+Dump I/O Controller Hub (ICH) southbridge GPIO registers
+.TP
+.B "\-r, \-\-rcba"
+Dump I/O Controller Hub (ICH) southbridge RCBA registers
+.TP
+.B "\-p, \-\-pmbase"
+Dump I/O Controller Hub (ICH) southbridge pmbase registers
+.TP
+.B "\-m, \-\-mchbar"

-.TH ICH_GPIO 8 "March 8, 2008"
-.SH NAME
-ich_gpio \- Intel southbridge GPIO Dump Utility
-.SH SYNOPSIS
-.B ich_gpio
-.SH DESCRIPTION
-.B ich_gpio
-is a user-space utility which can dump all
-register contents of the Intel ICH series Southbridges.
-.PP
-It is mainly used for coreboot development purposes (see coreboot.org
-for details on coreboot), but it may also be useful for other things.
-.PP
-Here is an example output:
-.br
-[root@localhost dumpgpio]# ich_gpio
-.br
-Intel Southbridge: 8086:24c0
-.br
-GPIOBASE = 0x0500
-.br
-gpiobase+0x0000: 0x1a003180

-.PP
-Please consult your datasheet for the register meanings.
-.SH OPTIONS
-No command line options needed just run ich_gpio.
