Missing drivers on the HP dc7800p with Windows 7

NOTE: I’ve recently moved this page from another domain and, previously, it had a lot of comments – i will try to migrate comments to this new page…

For reasons none of us will ever understand, though HP offers drivers for the dc7800p and Windows 7, there are a few drivers missing from the HP download page. Specifically, the HECI and LMS_SOL devices appear, after installation, with yellow check marks (no drivers installed). If the names of these rascals don’t ring a bell, they are identified in the Device Manager – as I recall – as  ”Unknown Serial Port“, and, “Unkown Device“.   It’s something like that – and a problem for pretty much everyone.

A few people have also reported that they could not find the proper audio driver, as well. While I don’t recall having a problem with the audio driver, it’s been a long time since I performed that particular installation. So, just to be on the safe side, I’ll post a link to the audio driver as well.

Since I posted a link on the HP site, a lot of people have visited and left positive comments. As I said at the top, I will try to get those comments moved to this new domain. I’m glad so many people found these useful.

Driver Downloads

Here are the drivers for the two most commonly elusive device drivers:
HECI Driver

LMS_SOL Driver

I mentioned that I didn’t recall having a problem with the audio driver, but one visitor (thank you, Jeff) left a comment and said that he couldn’t find the right audio driver on the HP site. If you’re having problems with the audio driver, here’s the file provided by Jeff:

Driver Updates

HP also offers some driver updates, which I performed. I put these things on the web to help others, and to make things faster for myself. Optionally, you might want to do these updates:

Chipset Update

Ethernet Driver Update

Thanks for visiting, and, I hope you found this helpful….

    Thank you so much. I had the “terrible two” and was able to nail down the one on my own, but the LMS driver was doing a very good job of hiding from me.
    Your fix worked. I very much appreciate it!

  3. The 7800′s I have had trouble with have now worked out great as far as the drivers listed here in DIY, for the PCI port issues, and controllers, with Win 7 x64 bit, …no problems what so ever. My other problem is, I’m now working on a DC7700, with a PCI Simple communications controller issue, and cannot find anything in HP regarding this issue, except other people going bald pulling their hair out. I tried the 7800 series drivers you have listed here, and to no avail, they didn’t work, along with also trying Vista x64 bit drivers, and w/ the same results, …also tried some of the xw series models drivers, ….and still the same issues. The 7600 ‘s boot up fine, with no issues in device manager, and well as the 7900 I have. I tried the chipsets from those, and same outcome. Also tried just for shi** and giggles an XP chipset, ..now ,that one seemed to almost work, …except that it informed me that it would only be applicable in x32 bit form. I tried Intel’s site,and here are my specs for the 7700: Intel Core 2 Duo E6300 Processor (1.86-GHz, 2 MB L2 cache, 1066-MHz FSB). But again, …Intel is kicking it back out faster than HP’s site did, …..any help would be greatly appreciated, as your site is the only site it seems on the net, that truly wants to help someone, instead of the Google round-a round, or no answers at all , ant help would be greatly accpreciated , ty, Sincerely, George Derment Jr. (geo66wizard@gmail.com)

      Thanks for the kind words, George – and I’m sorry the reply took so long… We don’t have a 7700 to test or we’d like to help. As is stands, we’ve got no experience with that unit – which stinks! I do apologize that we were so slow in responding. Did you ever find the right driver(s)….?
