First... EXCELLENT JOB with the fix on this! If it wasn't for you and the concise procedural outline you've posted here I would have NEVER been able to fix this!
Second, it was from the previous forum/postfix that I had bookmarked that also finally made this work and the LAST step I needed to do in order to make it work when I was done applying your steps.
I have an HP dv5000 from September of 2006. Here is the final step:
Run regedit. Key you want to edit is located in:
Original Key Value: SDParam = 16 (Decimal)
New Key Value: SDParam = 1
That's what made it work for me on the next reboot!!!
I am going to post this, along with your steps, on as many forums as possible so people can get this working to. Unfortunately, Microsoft locks up that hotfix so I will be zip the files I extracted from them and host them for free elsewhere.
Thank you again!!! You made my Christmas this year!
One computer geek to another!!!
I have an HP Pavillion dv8000 series laptop that has a Texas Instruments PCIxx12 Integrated FlashMedia card reader in it, but found when I purchased a 16GB SDHC memory card, my computer would not even recognize the card at all. After many hours of searching the net, and many wrong attempts at getting the TI card reader and Windows XP SP2 to properly read my high capacity SD card, I finally got it to work, hopefully this info will save someone from having to spend all the time I had to in order to get this to work... but rest assured, the TI intergrated card reader will work with SDHC memory cards after doing installing these fixes.
First thing that needs to be done is to obtain the Windoows XP HotFix which is here: http://support.microsoft.com/kb/923293
You will have to click on the link given on the above page to request this HotFix, and choose your Language, Operating system, and processor type, and Microsoft will email you the HotFix and give you a password that is needed to unzip the HotFix file... they sent it to me within about 30 minutes of my request. Apparently Windows XP can't read SDHC memory cards without this, even if you do have a compatible card reader. Once you recieve this file, install it.
Next, you need to obtain the latest TI Integrated FlashMedia card reader (which by the way, HP did NOT have listed for my model of computer). The driver version is 184.108.40.206 A, and can be downloaded at:
Now this driver says it's for Vista, but I assure you it works fine with Windows XP... as a matter of fact, the previous version of the TI FlashMedia software (220.127.116.11 A), simply will NOT support my 16GB memory card. Download the TI driver and install it, and upon rebootting your computer after installing these two fixes, you'll hopefully find you computer can now use the SDHC memory cards!
I suspect this TI driver and windows fix will probably work for any computers that have the intergrated TI FlashMedia card reader in it, but can't say for sure since I have only confirmed it got my HP dv8000 series notebook computer working with the SDHC card.
