PXE booting to BARTPE

PXE booting to ISO

Goal

We want to boot ISO images via PXE (rather than through CD). This means that, as long as we have enough RAM in the local pc's, we can boot BARTPE, WINPE and any LIVE CD (such as KNOPPIX, PCLINUXOS, UBCD, etc).

Assumptions

You are a network/server administrator and know what TFTP, BARTPE and PXE, a network boot, means. Your SME SERVER is your DHCP server.

Install TFTP package on your SME SERVER

-install SMESERVER-TFTP-SERVER on your SME SERVER: http://wiki.contribs.org/Tftp_server

Create a BARTPE.ISO on your local pc

-download BARTPE on your local pc: http://www.nu2.nu/pebuilder/

-create a BARTPE disk using WINDOWS SERVER 2003 source (i386 directory)

-you now have a BARTPE.ISO (on your local pc)

Obtain WINDOWS SERVER 2003 SP1 files needed

-download the WINDOW 2003 SERVER SP1: http://www.microsoft.com/downloads/details.aspx?FamilyId=22CFC239-337C-4D81-8354-72593B1C1F43&displaylang=en

(You now have a file called: WindowsServer2003-KB889101-SP1-x86-ENU.exe)

-open WINRAR to open the WindowsServer2003-KB889101-SP1-x86-ENU.exe file

-extract the following files from the W2K3SP1:

ntdetect.com
ramdisk.sy_
setupldr.ex_
startrom.n1_

-The underscore files are compressed. We need to decompress/expand them:

expand ramdisk.sy_
expand setupldr.ex_
expand startrom.n1_

Transfer files to SME SERVER

-copy the following files to the SME SERVER in the "/tftpdboot" directory:

ntdetect.com
setupldr.exe
startrom.n12
bartpe.iso

WORK WITH FILES IN THE TFTPDBOOT DIR

-the files are case-sensitive and need to be named exactly as follows:

ntdetect.com (lower-case)
NTLDR (rename the setupldr.exe to NTLDR, all caps)
startrom.0 (rename the startrom.n12 to startrom.0) (This is a ZERO)
BARTPE.ISO (all caps)

-create a winnt.sif:

vi winnt.sif

-the contents of the winnt.sif file:

[SetupData]
BootDevice = "ramdisk(0)"
BootPath = "\i386\System32\"
OsLoadOptions = "/noguiboot /fastdetect /minint /rdexportascd /rdpath=bartpe.iso"

-create a pxelinux.cfg directory:

mkdir pxelinux.cfg

-change to pxelinux.cfg dir and create a default file:

cd pxelinux.cfg
vi default

-the contents of the default file:

prompt 1
implicit 0
timeout 600
default foo
LABEL foo
   kernel startrom.0

Boot client PC

-that should do it! Start your client PC and boot from the network.

-at the prompt, when it asks for an image type: foo

-pretty cool, huh?
