>Description:
	SAMSUNG SP1203N 120GB hard disk couldn't be sometimes recognized by
	kernel even if BIOS and boot lorader recognized it.
>How-To-Repeat:
	SAMSUNG SP1203N 120GB hard disk has this problem 
	I can't test on another mother borad, but tested on some of the
	same model machine.
>Fix:
	Some hard disks needs more delay in sys/dev/ic/wdc.c.
	I don't know this is the right fix or not, but it seems to solve
	the problem.
