This table is created each time the system is booted and contains entries describing various pieces of hardware in the system. The items in the table include main memory size, cache sizes, floating point unit, and disk drives. Without arguments, the hinv command will display a one line description of each entry in the table. The -v option will give a more verbose description of some items in the table. The -c class option will display items from class.
Classes are processor, disk, memory, serial, parallel, tape, graphics, and network.
The -t type option will display items from type. Types are cpu, fpu, dcache, icache, memory, and qic. Otherwise, hinv exits with a value of 0.
