[Qemu-devel] WfW setup and DOS display.sys hanging

[Sebastian]

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.

Sebastian
