user intervention when boot different disk

Hello All, I got a question, but I can't find where to set it up. I need your help.

The systems are with solaris 10 and with two boot devices (disk 0 and disk1). When the operator wants to boot the different disk then the previous one, i want to get the user intervention to ask operator if this is the boot device that he/she really wants to boot it up.

For example, the current boot device is disk 0. when operator reboot the system from disk1, I want that the system can ask "the old boot device is dks0, are u sure you want to boot disk1 " something like that. I got few systems are have this, few not.

Anyone knows where to set it up?

Thanks a lot!

On OK,

run:

setenv auto-boot?=false

It will be prompting to choose the boot device.
Let us know it doesn't solve the purpose.

Thanks,
Deepak

Thanks a lot..Deepak,

but it looks like to set auto-boot? to false won't solve the issue, since I got the eeprom outcome for the working tool, and the auto-boot? is true. Any other possibilities?

Here is the eeprom outcome for the tool with user intervention when boot from different disk

you can't get the ok> prompt to be interactive as if compared to a shell.
you can only make ok> prompt to prompt for password when you need to issue boot commands, which comes with sparc security-mode.
once you set the auto-boot to false, shutdown(init 5) poweroff then on the system, you'll get the ok> prompt. type boot disk or boot disk1
