Jump to first page Project Purpose 1. Setup PCMCIA controller, let it probe correctly PCMCIA card attached on it. F 2. Set up Ethernet interface, including assign IP address, subnet mask to it. F 3. Setup PPP dialup client, write a script program using AT command set to dialup. Configure pppd to setup PPP interface.

Jump to first page Configureation Steps n Ethernet card, Modem,etc are installed onto laptop computer by PCMCIA controller as PCMCIA card. n PCMCIA card can include ethernet card, modem, memory card, serial card,SCSI&IDE card,etc. n PCMCIA support should be compiled into Linux kernel

Jump to first page Contd (Steps) n Put system reserved I/O port, memory into /etc/pcmcia/config.opts, in out project,parameter is : F I/O Range: 3E0-3E1 F Memory Range: D8000-DBFFF n Current release contain drivers for all the devices. All these drives are loaded as modules on linux. n When system(socket driver) detect the availability of pcmcia card in socket slots, it will run corresponding shell program under /etc/pcmcia to bring up interfaces. n Ethernet card will run network, modem will run serial,etc
