I have in my custody an Sco Xenix 2.1.3 system (corum.UUCP) that seems to work
just fine and dandy, but i'm curious about one thing (well alright, many
things, but i don't want to drown you out there... (:-)); the diagnostic/
informational messages that are printed on the system console at boot time
include one about the line frequency: "HZ=50".  Now, we are in the US so we
should be at 60Hz, right?  Why is this set to 50?  Does it affect the system
much?  Would the system be faster if its reset to 60?  Should i ignore this
message?

I looked through all the include files i could find and these slices are all
the references i could find to "HZ":

	 */
	#ifdef M_I86
	#define	HZ	20		/* Ticks/second of the clock */
	#define	SSIZE	1024		/* initial stack size (bytes) */
	#endif
	
	#ifdef M_I286
	#define	HZ	50		/* Ticks/second of the clock */
	#define	SSIZE	4096		/* initial stack size (bytes) */
	#endif
	
	
	 */
	#ifdef M_I86
	#define	HZ	20		/* Ticks/second of the clock */
	#define	SSIZE	1024		/* initial stack size (bytes) */
	#endif
	
	#ifdef M_I286
	#define	HZ	50		/* Ticks/second of the clock */
	#define	SSIZE	4096		/* initial stack size (bytes) */
	#endif

Hopefully not being a bimbo with a stupid question,
derek
