Updating System Firmware

Alright we have a strange problem that i never encountered.

We have a V445 Sun Fire we are trying to install it via a tadpole laptop (jumpstart laptop) the v445 takes the flash just fine, but we get an error upon reboot saying unable to locate boot device. Well our SUN guru said we need to install patch 121690-04 to fix this problem well one way to install is copy the file to / the at the ok prompt type boot disk /flash-update-SunFire445

well we can not do this since the system can not locate the boot device so that we can load it. So what i did next was boot net -s so i can boot from the Jumpstart laptop then i did a mount /dev/dsk/c0t0d0s0 /var/tmp I mounted it here since i needed /mnt for the Jumpstart laptop directory where the patch files are located. so i now have the following

mount -F nfs -o rw 10.200.xxx.xxx:/jumpstart /mnt
mount /dev/dsk/c0t0d0s0 /var/tmp
I copied over all the patch information to /var/tmp
then did a chmod 755 flash-update* files in that directory of /var/tmp

since it stated i needed to have those files on the local disk in root.

well the .sh script included in that patch refers to directories that in a normal operating state. ie. /kernel/drv but on a mounted system for me it is /tmp/root/var/tmp/kernel/drv when i do a pwd in that directory

do i need to change all the variables and the normal areas to have /tmp/root/var/tmp in front of them for the system to accept the system firmware patch correctly? every time i run the .sh i get "Could not find a writable driver location" i believe it is because it is trying to write to the local temp OS and not the real os hard drive locations.

NAME

       installgrub - install GRUB in a disk partition or a floppy

SYNOPSIS

       /sbin/installgrub [-fm] stage1 stage2 raw-device

       The installgrub command is an -only program. GRUB stands for GRand Unified Bootloader.

       installgrub  installs  GRUB  stage  1  and  stage  2  files on the boot area of a disk partition. If you specify the -m option, installgrub
       installs the stage 1 file on the master boot sector of the disk.

       The installgrub command accepts the following options:

       -f

	   Suppresses interaction when overwriting the master boot sector.

       -m

	   Installs GRUB stage1 on the master boot sector interactively.

       The installgrub command accepts the following operands:

       stage1

	   The name of the GRUB stage 1 file.

       stage2

	   The name of the GRUB stage 2 file.

       raw-device

	   The name of the device onto which GRUB code is to be installed. It must be a character device that is readable and writable.  For  disk
	   devices,  specify  the  slice  where  the  GRUB  menu  file	is  located.  (For Solaris it is the root slice.) For a floppy disk, it is
	   /dev/rdiskette.

       Example 1: Installing GRUB on a Hard Disk Slice

       The following command installs GRUB on a system where the root slice is c0d0s0:

       example# /sbin/installgrub /boot/grub/stage1 
		/boot/grub/stage2 /dev/rdsk/c0d0s0

       Example 2: Installing GRUB on a Floppy

       The following command installs GRUB on a formatted floppy:

       example# mount -F pcfs /dev/diskette /mnt
       # mkdir -p /mnt/boot/grub
       # cp /boot/grub/* /mnt/boot/grub
       # umount /mnt
       # cd /boot/grub
       # /sbin/installgrub stage1 stage2 /dev/rdiskette

       /boot/grub

	   Directory where GRUB files reside.

       boot(1M), fdisk(1M), fmthard(1M), kernel(1M), attributes(5)

       Installing GRUB on the master boot sector (-m option) overrides any boot manager currently installed on the machine. The system will always
       boot the GRUB in the Solaris partition regardless of which fdisk partition is active.
