'ram disks' as devices haven't been used in quite a while. The standard method of using filesystems in memory is 'tmpfs'. Try mount -t tmpfs -o size=nbytes /test/dir If you really need a ram disk (for non-filesystem uses, maybe?) you could create it with mknod /dev/ramdisk b 1 1 (IIRC, anyway). Then you can allocate the size using dd. -- Liam
