pb with silo & cdrom

[Eric Delaunay <delaunay@lix.polytechnique.fr>]

Hello,

  I'm trying to build a bootable CDROM with silo with no success.

I can boot the kernel from the CD but I get the following error while loading
an initial ramdisk:

  Image too large to fit in destination

  Internal error while loading physical blocks from device

I thought it was due to the compressed ramdisk, therefore I uncompressed it
then rewrote the CD (hopefully I used a CDRW medium ;-) ), but it always fails
to load the ramdisk :-((

What is wrong with my configuration ?

I put all the silo files under a /boot directory on the CDROM and the linux
files under /install:

/boot/
/boot/cd.b
/boot/second.b
/boot/silo.conf
/install/
/install/debian.txt
/install/linux
/install/root.bin

My silo.conf contains:

message=!cd1
timeout=300
image=!cd2
	label=linux
	initrd=!cd3

and I ran intelsilo [0.8.1 release] (yes I built it on my PC box) with the
following options:

intelsilo -r /mnt -c /data/slink1.raw -C /boot/silo.conf -l /install/debian.txt,/install/linux,/install/root.bin

The linux kernel is 1607596 bytes long. 2867200 for initrd file.

I'd appreciate any help.
Thanks in advance.

Eric.


PS: I have had to patch intelsilo not to abort while opening an unexistant
/data/slink1.raw under the chroot'ed environment.  See the patch below.
