It is a PCI card form factor. The epson chip does NOT have a PCI 
interface on board, so a PCI bridge chip is there to support PCI 
operation -- In short, if you want to use PCI, it is available by 
activating it with a DIP switch.  I did use it, and it works.

I believe the card is enough for browser operation, yes. I am not sure 
about playing video beacuse I have not performance-checked it , and as 
you pointed out, it is unaccelerated.  It should be able to display 
whatever you throw at it though, so if you can do the MPEG decoding 
completely in software on the MPC side, you should be fine.

Do you work at Turk Telecom or are you just a customer ? What is your 
project, if I may ask ?
