Steps needed:
1) create ramdisk
2) copy rc.liveboot to ramdisk
3) edit rc.liveboot on ramdisk
4) run rc.liveboot from ramdisk
5) exit

More details:

1) to create ramdisk, use lines from rc.liveboot. You view this file using command cat, i.e. writing “cat /etc/rc.liveboot | more”. Using down arrow key scroll nearly to the end of the file where you will see “RAMDisk()”. Now press “q”. The text will remain on the screen but you will be able to write commands. Here are commands you have to execute (one by one). Please note I changed:

- system-image=no in “hdik” line
- ram://51200 in “hdik” line
- $mntpt to /Volumes in “mount” line

Commands to execute:

dev=`hdik -drivekey system-image=no -drivekey eject-upon-logout=no -nomount ram://51200`
newfs $dev #hack to init partition table automatically
newfs_hfs $dev
mount -t hfs -o nosuid,nodev $dev /Volumes

2) If previous step finished without errors you have working ramdisk in /Volumes. Now copy rc.liveboot to it:
cp /etc/rc.liveboot /Volumes

3) To edit rc.liveboot on ramdisk type:
emacs /Volumes/rc.liveboot
Now scroll the file till line 85 and comment this lines (put # before them):
set ${volinfo}
devname=$1
fstype=$2
To save yor changes pres Ctrl+X and then Ctrl+C. Editor will ask you of saving changes, press “y”.

4) To run rc.liveboot from ramdisk:
sh /Volumes/rc.liveboot init 2000000
If everything works fine you should see two lines of text, first saying something like “messed with swap”

5) enter command “exit” and watch as your live Leopard is starting

Hope this helped.

Thank to creators of this great live distro!
