Happens with QEMM386 and HIMEM.SYS/EMM386.EXE. I guess the application does at this point swithing to 286 protected mode and trying to move conventional memory up to EMS memory. Issue is NOT present under VMWare Server 2.0 and with real hardware. DOS; MS-DOS 6.22 QEMU: 0.12.3 under Fedora 11, 2.6.30.10-105.2.23.fc11.x86 on AMD Phenom II Quad Core, x86_64-softmmu. Any comments or ideas (I guess something with protected mode and MMU might be wrong)? Thnx. Ciao, Gerhard -- http://www.wiesinger.com/
