Gnu Grub booting from CD

[Niklaus]

Hi,
 I have a bootable CD and normal ISO9660 data CD , both has linux on it.
 I don't have the BIOS password and hence cannot change the bios
startup options.

1) Is there any way to boot the CD from grub command line ?

2) Can i access the data in ISO9660 from grub command line ?

I can boot a floppy like root(fd0)
chainloader +1
boot

simlarly windows partition like root(hd0,2)
chainloader +1
boot

Is there anything for bootable CD .

How to access data in ISO CD . Can we do it like ext2 of harddisk.

Regards
Nik
