# set6x86(8)

access Cyrix control registers

## NAME

set6x86, get6x86 - access Cyrix control registers

## SYNOPSIS

**set6x86** \[ *-hpsc* \]  *register\_index* data

## DESCRIPTION

This utility program allows access to the special control registers of the Cyrix 6x86 processors.  This initial manpage is intended to satisfy the lintian requirements of a Debian package and will be improved after the other serious issues are cleaned up.

## PARAMETERS

**register\_index** An index to the specified Cyrix 6x86 config register in decimal (e.g. '24'), hex ('0x18') or octal ('030').

- **data**

  The data to program into the specified register (dec\|hex\|oct) (or the bitmask for the -s' (set) or -c' (clear) options).

## OPTIONS

**set6x86 accepts the following options:**

- **-c**

  The data is a bitmask for clearing bits in the register.

- **-h**

  The usage information is printed.

- **-p**

  The output is pipeable (in hex format).  Only the contents of the register is output.

- **-B**

  We now check /proc/cpuinfo to make sure it is a Cyrix cpu. This option bypasses the check.  It has only been tested on a MediaGX chip and expects the vender id to start with "Cyrix". This option allows setting other chips without that string.

- **-s**

  The data is a bitmask for setting bits in the register.
