HI Nick. :-)
I searched with chip number and I found card manuals.
Manual just shows the specification and features of
the card. I found base address and IRQ of each port is
allotted by system BIOS. I didn?t find driver code for
exact board but I got similar board driver code. That
code access BIOS space to get the port base and port
number information of a card.
Can we do the same in eCOS? I have already searched in
eCOS but I didn?t find any API to access BIOS space.
Thanks for your valuable suggestion Nick.. :-)
Thanks
