Hi,
I noticed in newer versions of Qemu (Debian Jessie) a regression causing
DISPLAY.SYS from MS-DOS 6.22 to hang the system as soon as loaded.
The Windows for Workgroups 3.11 SETUP.EXE file hangs with a cleared
screen and the cursor blinking in the top left of the screen. The
DOSIDLE.EXE[1] file hangs after printing out some system information.
Git-Bisecting returned "roms: update vgabios binaries" (commit
6eefccc0bb9c34051b1e21880fc3a1c1c8686edd) as the bad commit.
I tested the i386-softmmu target on Debian 7.3 (wheezy), x86_64 host and
gcc 4.7.2 (Debian 4.7.2-5) without KVM support.
