Please see http://www.cs.utexas.edu/users/kharker/linux-laptop/ for special notes regarding module or boot-time parameters to be passed to certain laptops, such as some of the Sony Vaio line and other laptops that use either PCMCIA or parallel adapters to access their CD-ROM drives. This version of the LNX-BBC Bootable Business Card supports PCMCIA Ethernet devices after boot; try "pcmcia start". You will usually need a non-PCMCIA CD-ROM drive to boot this CD-ROM, but see the above URL for more options on some laptops.
