Yes, that's right. Other missing pieces of info:

- I was using the elilo shipped with a RHEL4 beta
- my elilo.conf:

image=xen
        label=xen
        initrd=xenlinux
        read-only
        append="nomca console=ttyS1,57600 root=/dev/sda2"

xenlinux is a large uncompressed binary - so it's easy to hit space toabort it's loading.

Ok, this means it is using the plain_loader.c. But that should not
really matter.

Murphy's law. Now that I'm trying to debug, I can't reproduce the problem any more. Non debug: startup.nsh> elilo xen ELILO Loading xen.....done Loading initrd xenlinux...initrd.c(line 90):read initrd(xenlinux) failed: 1 ELILO boot: xen Loading xen...ConvertPages: Incompatible memory types plain_loader.c(line 292):relocation is disabled, cannot load kernel Exit status code: Load Error Debug output is also attached. One thing I noticed is that if the loading of initrd (xenlinux) fails, the memory for initrd is freed, but the memory for the main image (xen) is not freed? -Arun
