64 bit on solaris 7

[sunilprao]

Hi all,

Is there any way to check if my box is running on 32bit mode or 64 bit mode?

I checked dmesg and messages and syslog files but none had the information.

Thanks
Sunil

The command isainfo -kv will let you know whether the OS is 64 bit or 32 bit, the default startup is defined in /platform/sun4u/boot.conf man page, on systems containing 200MHz or lower UltraSPARC-I processors, the 32-bit kernel is chosen as the default boot file, on higher end systems, the 64-bit kernel is selected. See man boot(1M) for details.

Hope it helps,

Regards,
