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.
