Subject: [Qemu-devel] [PATCH v3 12/19] magnum: disable floppy DMA for now
Date: Tue, 26 Jan 2016 22:32:17 +0100	[thread overview]
Message-ID: <1453843944-26833-13-git-send-email-hpoussin@reactos.org> (raw)
In-Reply-To: <1453843944-26833-1-git-send-email-hpoussin@reactos.org>

Floppy uses the DMA controller in rc4030 chipset, and not the i8259 from the ISA bus.
It's better to disable DMA than to call the wrong DMA controller.
