[syslinux] help : extlinux

[Prakash C.S.]

hello,
	i want to boot linux from a usb pendrive of ext2 type.
	1st primary partition. i tried with extlinux.
	i just want only the kernel to load, no other files (init) i dont want.
	
	the / contains only 
	extlinux.sys
	extlinux.conf
	vmlinuz
	
	i created the extlinux.conf file
	DEFAULT BASE
		KERNEL vmlinuz
		APPEND sd0,0
	
	but on booting it shows the error message 
	Missing Operating System.
	
       what is the problem, i dont have too much experience in this.

bye
