How do I determine if a system supports a 32 and/or a

How do I determine if a system supports a 32 and/or a 64-bit kernel?

Added: 09/13/01

From the command-line
=====================
$ getconf HW_CPU_SUPP_BITS
32 ---> system supports only 32-bit
32/64 ---> system supports both 32 and 64-bit
64 ---> system supports only 64-bit

From SAM
========
1) goto Performance Monitors -> System Properties -> Processor
2) check Kernel Width Support: value

The following summarizes the 11.00 implementations supported on HP9000
Servers:

32-bit only
===========
* A-Class: A180/180C
* D-Class: D200/x10 (only w/ XSW 9806+)
Dx20/x30/x50/x60
* E-Class: all
* F/G/H/I-Class: all
* K-Class: K100/200/x10/x20
* T-Class: T500/520

32/64-bit
=========
* D-Class: Dx70/x80/D390
(Dx70/Dx80 supports 64-bit only w/ Firmware rev. 38.30+)
(D390 supports 64-bit only w/ Firmware rev. 38.31+)
(Dx70/x80/D390 require XSW 9808+ to run 64-bit)
and provide NO support for any EISA cards!)
* K-Class: Kx50/x60/x60EG/460XP/x70/x80
* R-Class: all
* T-Class: T600
* Enterprise Parallel Servers: all

64-bit Only
===========
* A-Class: A400/500
* L-Class: all
* N-Class: all
* V-Class: all
