how do I log into this machine - with a twist...
I know this topic has been covered in one form or another, but it hasn't been covered to handle my problem.

I was given a Sparc4 running Solaris 2.5.1

The root password is unknown. This machine has no cdrom drive and it has no floppy drive.

I tried booting into the single user mode, but that requires the root password.

Right now I'm at a loss. I have a Solaris 2.6 CD but as I mentioned no CDRom to access it. I was wondering if it's possible to put the CDRom in my FreeBSD server and somehow have the Sparc4 boot off the CD over the network.

The problem is the address of the Sparc4 not only in a different network, but it's a different class. Is there anyway I can change the ip address w/o logging into the machine?

If I am able to boot over the network and use the CD in my FreeBSD machine, how exactly would I go about 1. reinstalling the OS, 2. entering a new root password?

I'm really lost with this one... any and all help will be greatly appreciated.

Oh yeah... taking out the HD isn't really an option, because I don't have a SCSI controller... :/

mklnim

MKLNIM(1)						      General Commands Manual							 MKLNIM(1)

NAME

       mklnim - make Linux Netinstall Image

SYNOPSIS

       mklnim outputfile [path-to-cdrom]

DESCRIPTION

       mklnim  is  a  shell  script  that takes a SuSE, TurboLinux or a RedHat CDROM, or equivalent disk directory, and creates a network bootable
       image (NBI) that can be used with Etherboot (http://etherboot.sourceforge.net/) or  Netboot  (http://www.han.de/~gero/netboot.html).   This
       NBI,  when  booted via the network, will make the target computer behave just as if a CDROM boot (TurboLinux), or a floppy boot (RedHat and
       SuSE) had been selected.  A conventional install can be done from this point onwards.

       There are several occasions when this technique is useful: 1. It can be used to quickly boot a target computer when the floppy  loading	is
       very  slow. 2. In the case of TurboLinux, it loads the CDROM initial ramdisk which does not require any further floppy loading. In the case
       of RedHat, it only loads the floppy initial ramdisk which does not contain the material in the supplementary floppy, and may  require  more
       floppy  insertion.  3. It can start the install from a floppy of any size, not just 1.4 MB, or even from a floppyless machine, if one has a
       boot ROM (providing no further floppy access is required).  4. It could be used as part of an automatic installation process.

       Naturally, all this assumes that the infrastructure for diskless booting (bootp and tftp servers) has been set up.

BUGS

       If supplementary floppies are required, this script doesn't include that material in the network boot image. Please  feel  welcome  to  fix
       this problem.
