If the kernel is zimage.usb2, is the following correct:

BL2 ext2    loadlin zimage.usb2  root=/dev/hdb2 ro initrd=initrd.gz
BL2 ramdisk 	   		 root=/dev/ram rw  initrd=initrd.gz
BL3 ext2 			 root=/dev/hdb1 rw initrd=initrd.gz
BL3 loop			 root=/dev/loop0 rw initrd=initrd.gz

What is initrd.gz doing?  Why does regular BL use it for ramdisk and loop 
but not to boot to ext2?  Ubuntu apparently needs it to boot to ext2.

Thanks a lot.  I don't know why XP (2002) included my card when SW10.2 did 
not.
