CIFS and POSIX operating systems just really don't mesh well.  They can 
be made to use in combination to some degree, but I can only imagine 
trying to use a CIFS share for boot would end badly. Usually, one would 
use NFS rather than CIFS, as NFS is actually modeled off of POSIX 
filesystem structuring.

iSCSI is inherently different from NFS or CIFS.  NFS and CIFS are 
filesystems.  iSCSI is a network block device, similar to ATAOE or 
Linux's NBD.  You share a disk or disk image over the network, and then 
mount and use a traditional filesystem found on that.  I have a partial 
writeup on the wiki, but be aware that typically when people do iSCSI 
boot, it is done with a physical initiator (SCSI controller) rather than 
a software one like the page below describes.  NFS boot is a much more 
straight forward process.
