Multiple cards in Comedi

Dear Comedi users,

I am installing several Advantech PCI-1758 + PCI-1711 + PCI-1724 boards in
an Advantech Industrial Computer with 12 PCI slots. The installation of
comedi-0.7.60, and also comedilib-0.7.20 in RedHat 9.0 (2.4.20 kernel
version), has been completed.

The installation comes with the following default device files:
/dev/comedi0,
/dev/comedi1,
/dev/comedi2,
/dev/comedi3

Due to 11 (eleven) boards will be installed, I created some more devices
file, i.e.: /dev/comedi4 .... /dev/comedi10.

I am not able to perform the comedi_config for /dev/comedi4, /dev/comedi5,
... and so on. The attached file shows that only the first four defauld
device files are
sucessfully linked to the boards.

Can anybody share his/her experiences to work with multiple cards in Comedi?

Thank you very much and best regards,
Dadang Sastrawan
