Yes, but you are using a chainloader option as supplied
by Lilo/Grub you are not changing the actually boot device
which is still hd0.
The only way to boot from a CD-Rom other than setting it as 1st boot
device in the BIOS is to boot from a floppy which in turn boots
the CD-Rom, such as can be done with a Win98 Start-up disk or when setting
the Mandrake installation to run from the DOS prompt.
But in both of these cases you are creating an extra step not eliminating
one.
So if you wish to boot from the CD-Rom the easiest, simplist, quickest
solution
is still to change the setting in the BIOS.
