Subject: [Qemu-devel] [PATCH v3 8/9] fdc: fix seek command, which shouldn't check tracks
Date: Mon, 23 Jan 2012 09:50:39 +0100 [thread overview]
Message-ID: <1327308641-14736-9-git-send-email-hpoussin@reactos.org> (raw)
In-Reply-To: <1327308641-14736-1-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.
