Subject: [PATCH 7/9] Add documentation for extra boot parameters
Date: Thu, 26 Jan 2006 18:45:25 +0000 (GMT) [thread overview]
Message-ID: <20060126184525.8550.50440.sendpatchset@skynet.csn.ul.ie> (raw)
In-Reply-To: <20060126184305.8550.94358.sendpatchset@skynet.csn.ul.ie>
Once all patches are applied, two new command-line parameters exist -
kernelcore and noeasyrclm. This patch adds the necessary documentation.
