[pkg-wine-party] Bug#792125: Should suggest or recommend dosbox for DOS binary support

[Ben Hutchings]

Source: wine
Version: 1.6.2-22
Severity: normal

WINE includes 'NTVDM' support for running DOS programs within the same
filesystem namespace as the Win32/Win64 programs.  It prefers to use
DOSBox for this, but if not then the i386 build will try to use VM86.

I will be disabling VM86 in Debian i386 kernels starting with Linux
4.1 (see #792003).  It has never been available on amd64 kernels.
I also suspect that use of VM86 for DOS emulation depends on being
able to map low memory addresses, which has long been disabled by
default to mitigate the security impact of null pointer dereferences
in the kernel.  Certainly dosemu doesn't use VM86 in this case.

Ben.
