From 03ff3683be1e3a4e9644150b7f12f046374dcbcd Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Thu, 20 Oct 2011 16:37:26 +0200 Subject: [PATCH] pc: Fix floppy drives with if=none MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Commit 63ffb564 broke floppy devices specified on the command line like -drive file=...,if=none,id=floppy -global isa-fdc.driveA=floppy because it relies on drive_get() which works only with -fda/-drive if=floppy. This patch resembles what we're already doing for IDE, i.e. remember the floppy device that was created and use that to extract the BlockDriverStates where needed.
