Cube2 install problems - Kernel panic VFS

Hello all,

I'm new here... I allready got some hints from the list archives for which
I would thank everybody.

I'm trying to install Debian on a Sun Cobalt Cube2 with 32Mb ram
using the howto Martin Michlmayer.

The first problen I encoutered was/is that the DHCP server doesn't
acknowledges the IP for the cobalt. In the list i found a workaround
for this:

nfs /nfsroot vmlinux-2.4.27-r5k-cobalt initrd.gz

and than the execute (which I not completely understand)

execute initrd={initrd-size}@{initrd-start} console=ttyS0,{console-speed}

I used: execute initrd= filesize of initrd.gz @0 console=ttyS0,115200

After which I get the follow output and ending with a kernel panic

> execute initrd=1557955@0 console=ttyS0,115200
