Yeah ghost works fine in dos as far as imaging a host. It's just I want to
ghost the client from an image file located on a samba host. To do that I need
IP connectivity.
And yes I've look at G4U and definitly want to try it out in the near
future, but need to get something up interim.

Unfortunately, I don't know anything about the kepppxedos, but do have a
question of what you are trying to do? I assume that you are talking about a
Norton Ghos Image, and that is the reference to DOS.
I've used Notron in the past, but it failed to work with the later LVM
partitions, so I had to find a program that supported my lab setups. I found
that g4u worked fine, and later g4l also worked. G4U is netbsd bassed, and
g4l is linux based. Both use dd with compression and ftp to make and
restore images. G4L also includes NTFSCLONE for doing a faster copy of
the ntfs partition data. Niether program does on the fly resizing like Norton,
but do work with LVM and other partition types, and don't have the expense
of having to buy a license for each machine or getting a site license. My
college has a site license an older Norton Ghost, but didn't get any support
from them with the LVM failures.
Hopefully, you will get a response that works for your current setup, but if
not, you might want to look at other options. Also, udpcast is a program if
you want to image lots of machines at once.

Thanks HPA, this is where I was getting at... First am I going in the right direction? I can only get an IP in two ways for the client to boot up a samba share. One, if I somehow grab the IP from pxe process through a memdisk query.Two, if I make a second DHCP request. Option two according to security standards will only work if I can provide some sort of DHCP identifer for those clients. Being that this is DOS, I dont think there is any single identifer to point it out from anything else (correct me if I'm wrong, and I could not find anything in the DHCP packets for dhcpd.conf to work with). So that really only leaves me with option 1. Can you explain how I would do a memdisk query to retrieve the IP (if possible with /dos), Subnet Mask, and GW from the pxeprocess. Your also telling me that there is no reason use the keeppxe line, that is only to keep the undi driver around. Instead I would use "ipappend 1"?? Like this?

Hi Peter, yes that is correct. I am trying to load ghost under dos or any other
format.
I have no problem creating the disks so far, I can load the correct drivers
fine. The problem is when the client makes the second dhcp request it sends out
a DHCP discover packet to the DHCP server. Due to our security protocols we have
to somehow set a identifer in our dhcpd.conf to set aside this boot process from
any others. The easiest way is to use the DHCP Discover Option 60 Vendor Code
Identifer. Unfortunatly all the DOS network stacks that I've looked at
don't send out this identifer.
So really I need a way to either hack the dhcp process to output a vendor code,
or find one that will push out some kind of identifer that I can use in the
dhcpd.conf.
Currently I am using 'keeppxe' and the 3com undi driver.

Hello Jonathan,
what is your problem? As far as I suspect, you want to start via Ghost
under DOS with networksupport to store image files on the network.
A normal diskette may to small to get all your software on it. there
are to solutions to this:
* A simple solution will be to extend with winimage a pxe bootfloppy
from 1.4MB to 2.8MB and copy the ghost files to the bootimage. You
can use your normal bootfloppy as base for this (and do not use the
keeppxe option).
* The other solution will be to start ghost directly from the network
- you may need it anyway to store your image files
For multiple networkcard support under dos there are a lot of different
solutions, e.g. these 3 ones:
* If you want to autodetect your network card you can use tools like
nicfind from Shane Kent you just have to evaluate the %nicnum%
variable after starting nicfind.
* or use as a complete solution barts network bootdisk (based on the
modboot disk - a tricky solution).
These two solutions have to be adept to every different nic you use
and dos drivers must exist (not for e.gsome sis-nics). Also there are
some nics with bootix firmware that crash the nicfind autodection
(don't if this also occurs with barts network bootdisk).
* The third solution will be to use the keeppxe option. This solution
has the charm that your boot disk will get hardware independent
(if this leaves enought lower dos memory for ghost). Undi drivers
are only availible for MS-Net clients, other solutions like netware
clients are tricky but possible (you have to use shims for this).
Remark:
Keep in mind that, if you use himem in config.sys, that the testmem option
is set to off (otherwise your bootimage in memory may be corrupted by
himem).

Unfortunatly we can only pass DHCP ip's to hosts that exhibit a vendor code
'like windows/pxe/and other os's do". Unfortunatly DOS does not, so
we
cannot request a second IP after the pxe process to map samba shares. From

Use the keeppxe option in the boot stanza, and then use an UNDI driver
for your networking in DOS. Like it says in the documentation.
example pxelinux.cfg file
--snip

kernel memdisk
append initrd=my.img.gz keeppxe
--unsnip
you'll need to fix-up your net/protocol.ini and net/system.ini

and it picks up the (followed by \net\netbind.com)
We're using the 3com UNDI driver, which can be lifted from the 3com MBA

Note this doesn't restrict you to using 3com network cards, it works
