Where is Debian's initrd located?

[Dan Anderson <dan@mathjunkies.com>]

I'm trying to edit my LILO config so that I can run debian (which is on
/dev/hde5).

Where is the initrd for debian located?

I currently have something like this for my debian entry:

	image=/boot/vmlinuz-2.4.18-bf2.4
	label="Debian Linux"
	root=/dev/hde5
	initrd=/boot/???
	append="quiet devfs=mount hdc=ide-scsi acpi=off"
	read-only

I can't find any initrd file in /boot under the debian partition.  Am I
missing something?

Thanks in advance,

Dan
