initial ramdisk in ubuntu
 

hi everybody!
i need your help!
i have some problems with "initial ramdisk" (initrd).
i did with instructions of the following link
Linux initial RAM disk (initrd) overview
http://www.ibm.com/developerworks/li...inuxInitialRam
but my initrd not run.
after loading, it stopped,and failure notice :
"ramdisk : compressed image found at block 0
no filesystem could moun root,tried : cramfs
kernel panic-not syncing : VFS :unable to mount rootfs on unknown - block (104,1)"
they are some last lines on screen.
i don't know why!

Perhaps this is wrong forum (currently, LinuxQuestions.org > Forums > Linux > Linux - Newbie), you might want the mods (moderators) to move it to Ubuntu. At LQ, you can do this by reporting your post & making the request in your report.
