Hi Gustavo, If you look in the documentation "Device Drivers and Installation Commands" LNUX-1203-06, dated from January 21 2002, page 54, you do find the correct list of parameters expected by the channel device layer. The fourth parameter is the number of kilobytes you want to allocate for buffers that will be used by lcs (default is 0 = no decision but you have to specify it) and the fifth parameter is for the port number of your card.
