Is this why I cant load any 64 bit drivers? I did some research and read that you need firmware 3.x to run a 64 bit OS? Is this correct? When I finally did load the 32 bit drivers in win 7 I noticed it updated my firmware from 1.53 to 1.57 (or something like that, im not positive) I then installed win 7 32 bit and it loaded the drivers fine. I then installed win 7 64 bit and it still wouldnt load the drivers. I Installed xp 64 bit (since 8.3.4 supports 64 bit) and it would not load the drivers. Last month I decided to sell it to a friend so I used a old server i had lying around and put the card in. I *think* I had ver 7.x when It was up and running. At my wits end, wondering if anyone can offer some advice.īought this 1480 card new (its a legit card) in 2005 and ran perfectly up until I closed my business in 2008.
