How to specify local boot up disk in CD boot Grub?

Hi Solaris 10 Experts,

I am wondering what is the correct syntax to edit in Grub when trying to specify the local ZFS boot disk while booting up from a Solaris 10 x86 64bits DVD installation disk. In other word, I try to boot up from local disk without removing the Solaris installation disk from drive which is down in a locked up data center. Below is what the current Grub setting is:

 
Grub edit>kernel$ /boot/multiboot kernel/$ISADIR/unix �B install_media=cdrom
Grub edit>module$ /boot/$ISADIR/x86.miniroot

However, I have tried the following changes without success:

 
Grub edit>kernel /platform/i86pc/multiboot �B console=ttya
Grub edit>module /platform/i86pc/boot_archive
Error 15: File not found
  Booting command-list
 
Grub edit>kernel /platform/i86pc/multiboot �B console=ttyb
Grub edit>module /boot/x86.miniroot.safe
Error 15: File not found
  Booting command-list

I am following the instruction from http://docs.oracle.com/cd/E19253-01/817-5506/grub-1/index.html.

I would also like to find out where the current Grub boot up file is located in order to see what is the correct boot up device is in /boot/grub/menu.lst which gives nothing useful:

 
***Do not edit***
The menu.lst file for this system is in /rpool/boot/grub.

The filesystem on this server is as follows:

 
root@sydpathsr01 # zfs list -r rpool | more
NAME                                            USED  AVAIL  REFER  MOUNTPOINT
rpool                                          20.4G   208G    49K  /rpool
rpool/ROOT                                     10.8G   208G    31K  legacy
rpool/ROOT/hostname_srs_2                       10.7G   208G  6.59G  /

rpool/ROOT/ hostname _srs_2@hostname_srs_1         72.2M      -  4.48G  -
rpool/ROOT/ hostname _srs_2@hostname_srs_2         72.3M      -  6.59G  -
rpool/ROOT/ hostname _srs_2/var                   3.85G   208G  3.44G  /var
rpool/ROOT/ hostname _srs_2/var@base_srs_install  22.7M      -  1008M  -
rpool/ROOT/ hostname _srs_2/var@hostname_srs_1     14.7M      -  1.49G  -

As always, your valuable advice would be much appreciated.

Many thanks again,

George
