kernel panic and my memory block

[akonstam trinity edu]

I am getting a familiar message when booting my FC2 system but for the
life of me I can't remember what to do to fix it.

It is the well known:
kernel panic : no init found Try passing init= option to kernel.

Well the initrd file is there. /initrd exists. 

Could someone job my memory? Getting old is hell.
What might the init= option look like?
