Subject: [Qemu-devel] [PATCH] Serial: DOS Plus regression
Date: Sun, 28 Feb 2010 16:03:58 +0800 [thread overview]
Message-ID: <473191351002280003y34b9f473m27db1fea2cec1bb8@mail.gmail.com> (raw)
The commit in r1049 (serial interrupt fix (Hampa Hug)) prevents
booting Digital Research DOSPlus. Following patch partially reverts
that commit and makes DOSPlus booting in QEMU again.
