Title:
QEMU fails to boot DR DOS Plus since 0.6.1
Status in QEMU:
Fix Released
Has this bug been fixed by this commit here:
http://git.qemu.org/?p=qemu.git;a=commitdiff;h=1645b8eee558ffe2389

With DEBUG_SERIAL defined, serial logs:
serial: event 2
serial: write addr=0x01 val=0x02
serial: read addr=0x01 val=0x02

serial: write addr=0x01 val=0x00
serial: write addr=0x03 val=0x80
serial: write add

DOSPlus booting in QEMU again."
