dell latitude d820 pci and pcie bus configuration diagram
Posted on 2008-10-14
Anyone know where I can find some kind of a block diagram that will tell me if and how my Dell latitude d820 shares internal PCI buses and the such. The desktop motherboard manuals usually tell you which onboard IDE controllers, video cards, and PCI slots share data buses so that you can plan on not saturating one bus when you plug in data intensive devices such as video capture cards, gigabit NICs, etc. Like I know the 1384 port shares a bus with the PCMCIA slot so I am weary of trying to capture video throught the DV onto an external raid drive plugged into the PCMCIA slot.
I called Dell but their tech couldn't tell me.
My specific situation is as follows:
- I use an D-Dock with a PCMCIA card in it for VGA video capture card pushing almost 130MBs
- I have and external MAGMA PCMCIA to PCI bridge for some other video capture cards.
- I have an external eSata raid plugged into a eSata contorller in the express card slot.
If I try and use everything at the same time I imagine there will be a bottleneck somewhere.
I know a Desktop would be more appropriate for this but I have both business and portability reasons for doing it this way.
