[Dri-devel] Resetting secondary video adapter

[Jon S. <jon...@ya...>]

I ran across this program for resetting secondary
adapters. 
http://www.arava.co.il/matan/svgalib/hypermail/1660.html
Inside of the download you can build vbios.vm86. The
vm86 version worked on my Rage128. The x86emu version
runs, but doesn't reset the adapter.

I had tried hacking this code out of X86 without
success. I also tried moding lrmi. lrmi needs more of
the bios vectors, entry points, etc set up.

There are later versions of x86emu here
ftp://ftp.scitechsoft.com/devel/x86emu but I can get
them to build. 

On a related note, in redhat-config-xfree86 the probe
monitor button is always disabled on the secondary
adapter. This is because redhat-config-xfree86 uses
ddcprobe to do the configing. ddcprobe uses lrmi which
can't handle a secondary adapter.

The code in vbios.vm86 could probably be merged into
ddcprobe/lrmi to make it work. Then it would be easy
to give ddcprobe a reset parameter too.
