help
This option sets the maximum permissible HyperTransport
downlink width.
Use of this option will only limit the autodetected HT width.
It will not (and cannot) increase the width beyond the autodetected
limits.
This is primarily used to work around poorly designed or laid out HT
traces on certain motherboards.
