Hi,
When I run a program such as Duke Nukem, Dosemu quits with the following
error:
ERROR: BUG: dosemu touched the protected video memory!!!
ERROR: cpu exception in dosemu code outside of VM86()!
trapno: 0x0e errorcode: 0x00000006 cr2: 0x000a7000
eip: 0x08092657 esp: 0xbffff290 eflags: 0x00200246
cs: 0x0023 ds: 0x002b es: 0x002b ss: 0x002b
Page fault: write instruction to linear address: 0x000a7000
CPU was in user mode
Exception was caused by non-available page
ERROR: leavedos() called from within a signal context!
It works fine when running with direct video access on a console.
Other software such as Windows for Workgroups 3.11 and MS Word 6 for
Windows works without problems.
I tried it with Dosemu 1.2.0 RC1 and stable 2003. With both version
King's Quest seems to give the same problem. Prince of Persia works with
stable 2003, but I believe it didn't work with 1.2.0 RC1.
Am I doing something completely wrong or is this a bug?
Thanks in advance,
Julius
