Bootable CD/initrd problem

[Mark Glassberg]

I am trying to recreate a Slackintosh install cd with a new kernel.  My cd
boots on my B&WG3 with the "c" key held down.  When the kernel tries to make
/dev/ram0 the root device, however, it fails and the kernel panics.

Below is some detail on what I'm doing.  Any assistance would be greatly
appreciated.

Thanks in advance,
Mark

I use the following to create the image:
	mkisofs -hfs -part -map ~/Slackintosh/iso/maps -no-desktop \
	-hfs-volid "Yaboot_Boot_CD" -hfs-bless ~/Slackintosh/boot -r \
	-o yaboot-cd.iso ~/Slackintosh

The boot directory has:
	-r--r--r-- 1 root root 10485760 2006-10-06 15:04 initrd
	-r--r--r-- 1 root root     1852 2005-12-31 09:48 ofboot.b
	-rw-r--r-- 1 root root  1857228 2007-05-23 15:39 vmlinux
	-r--r--r-- 1 root root   145456 2006-08-19 07:29 yaboot
	-r--r--r-- 1 root root      518 2007-05-24 11:52 yaboot.conf

The map file reads:
	# This mapping is needed to successfully boot and to keep macos
	# from treating everything like a text file (ugly!)
	#
	# EXTN   XLate   CREATOR   TYPE     Comment
