AIX 64位问题

这是我看到对AIX 64位问题表述最简单明了的帖子：
The types of 64-bit processors are as follows:
PowerPC_RS64
PowerPC_RS64 II
PowerPC_RS64 III
PowerPC_Power3
PowerPC_Power3 II
This is directly from IBM:
COMMAND: bootinfo -K
Reports whether the system is running a 32-bit or
64-bit KERNEL.
- AIX4.3 has only a 32-bit kernel
- AIX5.1 has both 32-bit and 64-bit kernels. Only
one [1] can be active on a system [or within a
LPAR] at a time.
COMMAND: bootinfo -y:
Reports whether the CPU is 32-bit or 64-bit.
COMMAND: oslevel
Reports the AIX version.
COMMAND: smit load64bit
Used to determine/set the USER-SPACE runtime
environment is 32-bit or 64-bit
COMPATIBILITY OPTIONS:
Appl System
User Kernel
Mode Mode Hrdw Compatibility
------ ------ ------ --------------
Option 1: 32-bit 32-bit 32-bit No limitations
Option 2: 32-bit 32-bit 64-bit Note #1
Option 3: 32-bit 64-bit 32-bit Note #2
Option 4: 32-bit 64-bit 64-bit Note #2
Note #5
Note #7
Option 5: 64-bit 32-bit 32-bit Note #2
Option 6: 64-bit 32-bit 64-bit Note #1
Note #4
Note #7
Option 7: 64-bit 64-bit 32-bit Note #2
Option 8: 64-bit 64-bit 64-bit Note #3
Note #4
Note #5
Note 1: Requires AIX4.3 or later.
Note 2: Invalid - not possible to run 64-bit
kernel on 32-bit hardware.
Note 3: Requires AIX5.1 or later.
Note 4: 64-bit user-space appls:
bos.64bit fileset must be installed and
activated using the command "smit load64bit"
AIX4.3 64-bit appls not supported on AIX5.1.
They must be recompiled.
Note 5: The AIX5.1 32-bit kernel is default.
The AIX5.1 64-bit kernel is optional.
The AIX5.1 64-bit kernel is installed on
64-bit hrdw by default, but is inactive.
The AIX5.1 64-bit kernel can be activated at
install-time or later using "smit load64bit"
Use "bootinfo -K" to determine which kernel
is running.
Use "lslpp -h bos.mp64" to determine if the
64-bit kernel is installed.
