It doesn't seem to have a boot options menu ( f1 or f2 ) like some livecd distros. However, I viewed the isolux.cfg from my Feora box and there are some things you could try.
You could try booting into runlevel three and do XFdrake from there. To get into different run modes like that, type it in at the boot prompt.
For example:
livecd init 3
You could also try the second option by typing:
safeboot
Here is the isolinux.cfg
Code:
default livecd
prompt 1
timeout 50
label livecd
kernel vmlinuz
append livecd=livecd initrd=initrd.gz root=/dev/ram3 devfs=nomount psmouse.proto=imps acpi=ht nomce vga=788 keyb=us
label safeboot

append livecd=livecd initrd=initrd.gz root=/dev/ram3 acpi=off vga=normal keyb=us noapic nolapic noscsi nopcmcia nomce unionfs=no
