Thanks for the help Steve and Patty!! This is just an FYI to let you all know what I eventually got to work..... In my syslinux.cfg I was able to place the work "scsi": label onescscidrive kernel vmlinuz append ks=nfs:10.1.1.1:/redhat.disks/ks.cfg scsi initrd=initrd.img network In the post section of the ks.cfg file I was able to grep the commandline as such: cat /proc/cmdline | grep scsi Then I looked at the return value to see if the word scsi was found or not (grep returns a 0 if the word was found).
