Hello all,

I have a bttv848  compatible PCI Tv Card (It's A Miro Media PCI TV Card -
circa 1996).

It works perfectly under win with the miro drivers, but unfortunately
Miro was taken over recently by Pinnacle and I am quite sure that Miro
offer no support for Linux users.

The card, however does run under Linux but it's a matter of
configuration. I've been trying off and on to configure it for a long
time now, but I've not had much luck,

I reckon I'm quite close now:

I have found a bttv848 driver on www.rpmfind.net - It installs fine with
no warnings (although it is an rpm!)

when I run it, It wants to use /dev/video to display the output.
I don't have /dev/video. 

doing a cat /proc/pci lists:

	Bus 0, device 11, function 0:
		Multimedia video controller: Brooktree Bt848 (rev 17).
		   Medium devsel. Fast back-to-back capable. IRQ 10. Master Capable
Latency=32.  Min Gnt=16.Max Lat=40.
		   Prefetchable 32 bit memory at 0xe30000000 [0xe30000008]

I imagine all i should need to do would be something along the lines of
(as root)

#cd /dev
/dev# ln -s /dev/device_on_irq_10 /dev/video

it's just i don't know what or how to assign that device on irq 10.
please tell me if I'm completely wrong. There are no specific howtos on
this subject, I have looked. Please don't flame me.

Many Thanks In Advance,

Alistair Ross.
