 *
 * Name: sizer.h
 *
 * Modification History
 *
 * Aug 10, 1990 - Randall Brown
 *	Added include file <sys/devio.h>
 *
 * Dec 12, 1989 - Alan Frechette
 *	Added include file <sys/sysinfo.h>. Added new field
 *	"alive_unit" to alive device structure.
 *
 * July 14, 1989 - Alan Frechette
 *	Added define for XMINODE.
 *
 * Jun 19, 1989 - Darrell Dunnuck (darrell)
 *	Fixed include of cpuconf.h -- had given Alan wrong info.
 * 
 * May 10, 1989 - Alan Frechette
 *	Added a new name list element "NL_roottype" for determining 
 *	network boots.
 *
 * May 02, 1989 - Alan Frechette
 *	Changes to deal with new unique "cpu" handling for both
 *	vax and mips architectures. 
 *
 * Feb 12, 1989 - Alan Frechette
 *	New sizer code which supports multiple architectures.
 *      This file is a complete redesign and rewrite of the 
 *	original V3.0 sizer code by Tungning Cherng.
