Responses are summarized
=======================

1.      http://soldc.sun.com/articles/64_bit_booting.html

2.      boot from the file /platform/sun4u/kernel/sparcv9/unix
        OK>boot <boot_disk> /platform/sun4u/kernel/sparcv9/unix

3.      Document ID 21434 FAQ on Booting Solaris to either the 64-bit
kernel or
        the 32-bit kernel

4.      /usr/sbin/eeprom boot-file="kernel/sparcv9/unix"        then
reboot

5.      Login as root and use the eeprom command to set the boot-file
parameter
        to the 32-bit kernel:
                # /usr/sbin/eeprom  boot-file="kernel/unix"

        The next system reboot will boot the 32-bit kernel or
                (OR)
                ===
         vi /platform/sun4u/boot.conf
                uncomment and verify that the line looks exactly like
this:

           ALLOW_64_BIT_KERNEL_ON_UltraSPARC_1_CPU=false
    reboot and then once the system is back up, verify that it is truly
running
        32-bit with "isainfo -b"


6.      eeprom or the ok prompt

                boot-file = kernel/unix
                Will always boot into 32-bit mode


Thanks
