I did:
lspci -v > pcifile

at root

and then

cat pcifile

it did show info, but I thought it would create a txt-file. where can I find it?

it shows this text about the RME:
(03:00.0 Multimedia audio controller: Xilinx Corporation RME Hammerfall DSP (rev0b)

Flags: stepping, medium devsel, IRQ3
Memory at 20800000 (32 bit, non-prefetchable) [size=64k]

Is that useful?

THanks a lot for your help so far! I am sure I will start making some music on Linux one day

Oh... I am running from CD-rom and didn't do an installation (need to clean up the junk on my harddrives etc..)
