Would there be any alternative display cards that can be used, if this PCIE based display protocol is an actual industry standard used in other embedded applications? --- End quote --- What is the motherboard? Is it an Intel D915GUX? The Intel D915GUX motherboard GMA900 Graphics Controller contained within the Intel 82915G GMCH (Graphics and Memory Controller Hub) supports an ADD2 card (Advanced Digital Display Card – 2nd Generation) in the PCI Express x16 slot. There is only one PCI Express x16 slot on the Intel D915GUX motherboard, so there is no question about installing the card in the correct slot. The ADD2 card isn't really an industry standard, it is an Intel chipset specific interface. https://en.wikipedia.org/wiki/Serial_Digital_Video_Out |

The motherboard is indeed an Intel D915GUX. Thank you for that additional clarification regarding ADD2. I guess I'm in luck that Agilent decided to use a fairly uncommon and (now antiquated) Intel proprietary interface to drive the display! I have ordered both the Chrontel CH7308 chipset IC and new 14.318 MHz crystals. I will update once those parts have arrived and I have a chance to place them on the board and retest. I noticed that the system only has 1G of ram and uses a 2.9 GHz celeron. I ordered up 4x 1G sticks of ECC 533mhz ram and a Pentium 4 640 which should be compatible with the chipset and bios on this board. Also a 64G intel SLC SSD. Nothing like a little retro PC build. The first machine I ever built was also an LGA775 board, but that supported the awesome q6600 which I had cranked up to 3GHz. Cooler master 690, big typhoon cooler, evga 8800 GTS's in SLI... when life was simple. |

I have an Agilent 16901A logic analyzer which also uses an Intel D915GUX motherboard. Without double checking, I'm pretty sure it also uses the same 0960-2530 LVDS display adapter card. (There are also later versions of the 16901A which use an Adlink M-880 or M-890 motherboard. Those Adlink motherboards have the LVDS display connector integrated on the motherboard). The standard CPU on the Intel D915GUX motherboard version of the Agilent 16901A logic analyzer is an Intel Celeron 352 - Celeron D CPU 3.20GHz. I haven't tried to upgrade to a faster processor. I did upgrade the standard 1GB of system RAM to 4GB. Without checking I'm not sure how much system RAM was actually available to the OS, I think it was closer to 3GB than 4GB after the BIOS subtracts reserved sections of the motherboard address space. |

Beware, the display settings seems to be saved in your motherboard bios. I've decided to upgrade the internals and now my LVDS output is not working as VBIOS of new board is not configured properly. |
