## NAME

inteltool - a tool for dumping Intel(R) CPU / chipset configuration parameters

## SYNOPSIS

**inteltool \[-vh?gGrpmedPMaAsfS\]**

## DESCRIPTION

**inteltool** is a handy little tool for dumping the configuration space of Intel(R) CPUs, northbridges and southbridges.

This tool has been developed for the coreboot project (see **https://coreboot.org** for details on coreboot).
