= Handling Problems =

== Custom Resolutions ==

The custom resolution feature is experimental and may not work in all cases. The custom resolution feature works by patching the video BIOS. Newer Intel BIOS and ATI/ATOM BIOS are supported. Nvidia BIOS support is coming soon.

By default, the Panorama driver will query the display resolution and timing (EDID) via the Display Data Channel (DDC). 
If this succeeds, the Panorama driver will automatically convert the 1600x1200 entry in the list of available
resolutions that are displayed in the Screen Object settings to the native display resolution. 
You can then select the desired resolution from the list. This is the best method of operation since the exact timings that are
provided by the display are used.

If you have problems with the custom resolution feature, the !PanoUtil.exe program can be used to control the custom resolution functions. 
If you happen to boot to a resolution that cannot be displayed, you can type CTL-ALT-DEL to activate the 
CAD handler and go to a command prompt to execute these commands. If CTL-ALT-DEL does not work you can boot to a command line using ALT-F1 then F2 and use the !PanoUtil command that way.

To reset all the custom resolution settings to the default and set the PM resolution to 800x600:
{{{
PanoUtil -r
PanoUtil -p
PanoUtil -e 0
}}}

To manually set a custom resolution of 1920x1080:
{{{
PanoUtil -c 1920 1080
}}}

To remove the manual custom resolution:
{{{
PanoUtil -r
}}}

To completely disable all the custom resolution support:
{{{
PanoUtil -d
}}}

To reset the Presentation Manager selected resolution to 800x600:
{{{
PanoUtil -p
}}}

To see the status of the custom resolution settings:
{{{
PanoUtil -s
}}}

All of these commands can also be executed from a different boot partition if you specify the drive to operate on. For example, to change the settings on drive d:, add the drive specification to the end of the desired command:
{{{
PanoUtil -s d:
PanoUtil -r d:
PanoUtil -p d:
PanoUtil -c 1920 1080 d:
PanoUtil -d d:
}}}

== Collecting a Testlog Log ==

1. Make sure your system is booted with the Panorama driver installed
2. Navigate to the \Panorama directory on your boot disk.
2. type: 
{{{
testlog panorama
}}}
5. Attach the LOG file to your ticket.

== Systems Running the Debug Kernel Might Get an Unexpected Trace Interrupt ==

The video BIOS in some systems will sometimes generate an unexpected trace interrupt when the system is running the debug Kernel. You can simply disable the trace interrupt handling using the "vc 1" kernel debugger command.  Systems running the retail kernel are not affected.
