Sorry, your computer does not have enough memory

    Hi,

  I have replaced the kernel of the 'rescue' disk by a 2.3.x. The
older kernel is bigger then the new one. After booting, kernel
ask to me to insert the root disk. So, I insert the root disk
and after starting loading, I obtain the folowing message :
"Sorry, your computer does not have enough memory"
  I try to tell that it can find 1BG of RAM ;)

  Any idea ?

Stephane.
