(I can't reproduce the dosidle problem.) The attached patch does indeed fix both the DISPLAY.SYS and Windows Setup problems for me. Thanks a lot! I can't reproduce the dosidle-problem either, it works now. A straight non-networked Windows for Workgroups 3.11 installation now hangs after loading the Program Manager. I noticed that SeaBIOS does not work correctly with parallel make, log excerpts following: $ LANG=C make -j16 # dual-core machine without SMT Compiling IASL out/src/fw/acpi-dsdt.hex make[1]: warning: jobserver unavailable: using -j1.

Okay, I hae pushed that patch into mainline. > A straight non-networked Windows for Workgroups 3.11 installation > now hangs after loading the Program Manager.
