The alpha1 release of the 1.1 xthd code is online at: ftp://shell.sgi.com/collect/xthdAlpha . The file is: xthd1.1alpha.tar
NOTE
To use the new 24Hz timings supported in this release you'll need an
updated vl.h file.
The vl.h will be standard in 6.5.6, but for now, rather than getting
the 6.5.6 images,
just use the included vl.h in place of /usr/include/dmedia/vl.h (be
careful to replace
the actual file and not just a symbolic link in one of the other
include directories).
Differences from 1.0 MR are:
Support for 24P and 24PsF. Specifically, these new vl timings are now available:
VL_TIMING_1125_1920x1080_24p VL_TIMING_1125_1920x1080_2398p VL_TIMING_1125_1920x1080_24PsF VL_TIMING_1125_1920x1080_2398PsF
Below are the supported genlock modes:
23.98P Tri-level Sync Reference -> 23.98P and/or 23.98PsF output; 23.98PsF Tri-level Sync Reference -> 23.98P and/or 23.98PsF output; 24.00P Tri-level Sync Reference -> 24.00P and/or 24.00PsF output; 24.00PsF Tri-level Sync Reference -> 24.00P and/or 24.00PsF output.
These are modes we plan to support in the future, but are not implemented yet:
23.98P and 23.98PsF digital input -> 23.98P and/or 23.98PsF output; 24.00P and 24.00PsF digital input -> 24.00P and/or 24.00PsF output; Color NTSC Bi-level Sync Reference -> 23.98P and/or 23.98PsF output; Color NTSC Bi-level Sync Reference -> 24.00P and/or 24.00PsF output; 1080i59.94 Tri-level Sync Reference -> 23.98P and/or 23.98PsF output; 1080i59.94 Tri-level Sync Reference -> 24.00P and/or 24.00PsF output; 25P output stand-alone or genlocked.
Duallink support is still under development. It is not yet fully functional and we do not recommend using it at this time.

Use hinv -m to check the hardware:
burgers 1# hinv -m | grep HDTV HDTV1 Board: barcode DPD520 part 030-1282-002 rev D HDTV_GENLOCK Board: barcode DPD462 part 030-1382-004 rev B
The thing to pay attention to is the part number. MR hardware is 1282-002 rev D and above, and 1382-004 rev B and above.
Use showprods to see if you have the MR software:

The thing to notice is that the MR software says "HD I/O" and previous software says "XT-HDIO". I know it would have made more sense to change the version number, but, the easiest way to tell is this little subtlety.
You must have 6.5.4 installed BEFORE you plug in your XTHD board. If you cloned a 6.5.4 disk and tried to use it in a system that previously had 6.5.3 or earlier, the system will not boot with the XTHD installed. PROMS prior to 6.27 mistake XTHD for graphics and tries to initialize it.
Boot the system without the XTHD board installed and type 'flash -o' at the command prompt. If you use inst to upgrade to 6.5.4, this step happens automatically. But you still have to upgrade to 6.5.4 BEFORE you plug the board in.
Here is the description of the four 50 pin connectors:
Here are the differences between the "Panasonic" and "Philips" pinouts:
Some of the XTHD boards have an unnecessary washer on the CPOP connector that makes it hard to install the board. It causes the screw to hang up on the slot outline. It is easy to remove this washer if it causes trouble. Its near the CPOP on the bottom side of the board. (The 'CPOP' is the high density 96 pin connector that brings the XTALK signals to the board.)
Here is a 1920x1080 test image that we use.
