Thanks for reply. But still not got it clearly. To get the result of command:"grep ramdisk /etc/fstab", ramdisk need to be mounted first. How do I mount ramdisk? I'm using the GENERIC kernel, Do I need to change the config file or rebuild the kernel? I also tried command "rdconfig /dev/rd0a 2048", but it reported "/dev/rd0a: Device not configured", how to deal with this?
