If you want to use both cards at the same time, your oscam.server will have to include two reader entries, something like:

#
# Read more: http://www.streamboard.tv/svn/…/doc/txt/oscam.server.txt
#
# Internal reader upper (or if the box has only one reader)
#----------------------------------------------------------
[reader]
label = upper
enable = 1
protocol = internal
device = /dev/sci0
group = 1
emmcache = 1,3,2
blockemm-g = 1
blockemm-unknown = 1
#below optional entries I've used for TV-Vlaanderen
cardmhz = 500
ratelimitecm = 4
ratelimitseconds = 10
#caid = 0100
#auprovid = 00006C
# Internal reader lower (boxes with two readers)
#-----------------------------------------------
[reader]
label = lower
enable = 1
protocol = internal
device = /dev/sci1
group = 1
emmcache = 1,3,2
blockemm-g = 1
blockemm-unknown = 1
I have a TV-Vlaanderen card running in the lower configuration.
The upper configuration is a merge from what I had on my previous box, it's still a work in progress and I have to check if it works with more than one channel at a time.
