hello i would just like to KNOW how you can determine which type of pci slot you have?
how do i know whether i have 32 bit or 64 bit pci slots?

i am looking to buy a ETHERNET card and some of them have 32 bits and some have 64 bits so i need to know.

thanks for any help.
Exactly what is the MAKE and model of your computer and/or motherboard?

I believe it's highly unlikely you have 64-bit PCI slots. Per http://www.soundonsound.com/sos/dec04/articles/pcnotes.htm:
"I've never seen any 64-bit slots or expansion cards either, and none of the motherboards in any of the PCs I've had during the last 13 years have featured any PCI slots other than standard-width 32-bit ones running at 5V, with a 33MHz clock and 133MB/second maximum throughput."

And, where did you even find a 64-bit Ethernet card? Everything I see at Newegg.com is 32-bit; see
Network Interface Cards (x) > Interface : PCI

So, get a 32-bit card. thanks for your help. im UNSURE of my motherboard make but this is the SITE where i saw the 64 bit Ethernet card
