Wonders !

I was about to give the card it's last rites. I thought well let me
try under the other OS

I didn't have any drivers for the same, since the demodulator driver
doesn't exist in the other OS also, but the bridge device does have
the driver.

I plugged the card in, the OS searched for drivers, since i didn't
have any didn't load any..
So it went under a question mark.

Looking under Resources,

It showed the PCI information string like this ..

PCI\VEN_1822&DEV_4E35&SUBSYS_00311822&REV_01\4&2E98101C&0&10F0

then i thought try with the driver eventhough support for the
demodulator doesn't exist ..

Downloaded and installed drivers ..

Lo ..!

Memory Range: F87FF000 - F87FFFFF
IRQ : 17

it got assigned a memory region indeed.

So, to wrap it up, the device is not dead .. We have something wrong
in the PCI subsystem probably.
