From c52acf60b6c12ff5eb58eb6ac568c159ae0c8737 Mon Sep 17 00:00:00 2001 From: Pavel Hrdina Date: Wed, 13 Jun 2012 15:43:11 +0200 Subject: [PATCH] fdc: fix implied seek while there is no media in drive The Windows uses 'READ' command at the start of an instalation without checking the 'dir' register. We have to abort the transfer with an abnormal termination if there is no media in the drive.
