I had to upgrade my personal laptop which is HP DV6000 ( Part # DV6775US ) to Vista 64-Bit Ultimate edition. I took the laptop with Vista Home premium 32-Bit and have used it for a while. I have decided to upgrade my laptop to 4GB of ram and discovered that 32-Bit won’t use all of it and i would still be capped with 3GB of ram. As RAM and Hard drivers are getting cheaper I ordered both additional 2GB of ram as my original configuration had 3GB ( 1x2GB and 1x1GB module) and a 320GB 7200RPM 16 MB Cache Seagate internal SATA-II hard drive.
I decided to do a clean install as upgrading the existing 32-Bit Vista OS will carry over a lot of crap HP Software. I did not even go ahead to analyze if the upgrade was even possible moving from 32-Bit to 64-Bit. Now it was time to check if I had 64-Bit drivers. Well it was not a surprise, HP never bundles the drivers disk with the newer cheap laptops (and this is the reason they are cheaper) and also they do not even distribute/support 64-Bit drivers on its support/download site cutting them additional cost and bringing the cost of laptop down.
Where do I get the 64-Bit drivers from? Well they are on your disk C:\swsetup\ its not organized but all of the drivers are in there. Browse to random directories and can you can see that each device drivers folders had x86 and x64 Vista64 folders so I was pretty confident that these will work. I made a backup of them on the new hard drive (the new hard drive was already partitioned and plugged in my USB)
As I had the newer hard disk on which I intended to install 64-Bit vista I did not bother to make backup of my existing install. Went ahead and fitted the new hard drive, inserted the vista cd and… I will not discuss any further as this is no brainer. Vista 64-Bit Ultimate was up and running. I loaded drivers one by one which went smooth and I could see Unknown devices in the Device Manager to disappear. Image of what my device manager looked like.
I can now access entire 4GB of RAM. There was a significant performance improvement by adding 7200RPM disk and also I had updated my Vista to SP1 which in my opinion drove me to use Vista.. as always by SP1 lot of bugs are resolved and you are assured to get a product which has been tested in Real world and not just labs.
In case if anyone reading this is interested to have 64-Bit drivers drop me a comment and I would upload it. all drivers currently are approx. 380MB uncompressed and so I am not uploading it with this post.
EDIT: I have uploaded the driver here
