I have a Gateway M500 laptop which is loaded with FC1. This laptop supports Secure Digital cards. I bought a 64M kingston card and tried to load but got some error messages. I did put the following in modules.conf: add options scsi_mod max_scsi_luns=255 I also did something possibly stupid: I read somewhere that mkinitrd would set up the SD card, but I didn't see how that would work so I started reading through /sbin/mkinitrd and then did "dd if=/dev/zero of=/dev/sda bs=1k count=64" to set up the disk. I don't know what I am doing here. Here are error messages on boot. Anyone have hint on where to go?
