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.
