Subject: [Qemu-devel] [PATCH v4 10/11] fdc: fix seek command, which shouldn't check tracks
Date: Mon,  6 Feb 2012 22:29:11 +0100	[thread overview]
Message-ID: <1328563752-3976-11-git-send-email-hpoussin@reactos.org> (raw)
In-Reply-To: <1328563752-3976-1-git-send-email-hpoussin@reactos.org>

The seek command just sends step pulses to the drive and doesn't care if
there is a medium inserted of if it is banging the head against the drive.
