PXE Network Windows Installation

Howto use your Funtoo machine to serve a MS Windows installation over the network In this guide we will assume that you have followed the PXE Network Boot Server Wiki article and have a working network/pxe boot setup. As of now this guide will cover Windows XP. Soon it will be expanded to also cover Windows 7.

Prerequisites

1. A working Funtoo installation
2. A working PXE Setup (DHCP, TFTP, PXELinux)
3. app-arch/cabextract
4. A legitimate copy of Microsoft Windows
5. Driver for your NIC - Suggested to use a complete driver pack with all major supported NIC hardware for the version of Windows to be installed.
6. RIS Linux toolkit >=0.4
7. A working Samba server setup

Creating the Windows XP Image

• In the previous guide, PXE Network Boot Server, we used /tftproot as the working directory so we will also use it in this guide for convenience. If you chose to use a different working directory then please apply it where needed in place of the /tftproot we will be going by here.

First you will need to create an ISO from your Windows XP installation disc. If you already have the ISO image you may skip this step.

 dd if=/dev/sr0 of=/tftproot/winxp.iso 

If your cdrom device isn't /dev/sr0 please use the appropriate device in this command.

Mount the ISO and Prepare Installation Sources

Mount Image to /tftproot/cdrom

mkdir /tftproot/cdrom; mount -o loop /tftproot/winxp.iso /tftproot/cdrom 

Create the new directory for the network installation files and copy the needed files to it

 mkdir /tftproot/winxp; cp -R /tftproot/cdrom/i386 /tftproot/winxp/i386

Depending on your CD/DVD copy of windows the directory name may be I386 as opposed to i386, if that is the case you will just need to change the first part of the command, keeping the new directory name i386 - this is going to be very important later on when creating the remap file! Check the contents of your newly created i386 directory to see if the filenames are in all CAPS or if they are already in lowercase.

 ls /tftproot/winxp/i386

If you happen to have all UPPERCASE filenames, lets go ahead and run a script to convert it to all lowercase:

 cd /tftproot/winxp/i386;ls | awk '$0!=tolower($0){printf "mv \"%s\" \"%s\"\n",$0,tolower($0)}' | sh 

Extracting and Modifying the Required Boot Files

Install app-arch/cabextract

emerge -av app-arch/cabextract

Extract the prepackaged drivers:

cd /tftproot/winxp/i386;cabextract driver.cab

Install support for a large list of network cards

cd /tftproot/;wget http://downloads.sourceforge.net/project/bootfloppy/pxefiles.tar.gz
tar zxvf pxefiles.tar.gz; cp pxefiles/drivers/* winxp/i386/

Copy the BINLSRV /INFParser tools to /tftproot

cp pxefiles/script/* /tftproot/

Extract the netboot startrom:

cd /tftproot; cabextract winxp/i386/startrom.n1_

Fix the startrom for netbooting xp:

sed -i -e 's/NTLDR/XPLDR/gi' startrom.n12
mv startrom.n12 winxp.0

Fix XPLDR:

cabextract winxp/i386/setupldr.ex_
sed -i -e 's/winnt\.sif/winxp\.sif/gi' setupldr.exe
sed -i -e 's/ntdetect\.com/ntdetect\.wxp/gi' setupldr.exe
mv setupldr.exe xpldr
cp winxp/i386/ntdetect.com ntdetect.wxp

Creating a remapping file

Create the file /tftproot/tftpd.remap and add the following to it:

ri ^[az]: # Remove “drive letters”
rg \\ / # Convert backslashes to slashes
rg \# @ # Convert hash marks to @ signs
rg /../ /..no../ # Convert /../ to /..no../
rg A a
rg B b
rg C c
rg D d
rg E e
rg F f
rg G g
rg H h
rg I i
rg J j
rg K k
rg L l
rg M m
rg N n
rg O o
rg P p
rg Q q
rg R r
rg S s
rg T t
rg U u
rg V v
rg W w
rg X x
rg Y y
rg Z z
r ^/(.*) \1
r ^xpldr xpldr
r ^ntdetect.wxp ntdetect.wxp
r ^winxp.sif winxp.sif

Install/Configure Samba

If you don't already have samba installed then:

emerge -av net-fs/samba

Create a Samba share for your tftp server in /etc/samba/smb.conf *Be sure you have the other required samba settings configured in the file

[Global]
interfaces = lo eth0 wlan0
bind interfaces only = yes
workgroup = WORKGROUP
security = user

[tftproot]
path = /tftproot
browsable = true
read only = yes
writable = no
guest ok = yes

Start Samba:

/etc/init.d/samba start

or if samba has already been started:

/etc/init.d/samba restart

Creating a Setup Instruction File

Create a the file /tftproot/winxp.sif and add the following, replacing SAMBA_SERVER_IP with the local IP address of your samba server:

[data]
floppyless = "1"
msdosinitiated = "1"
; Needed for second stage
OriSrc = "\\SAMBA_SERVER_IP\tftproot\winxp\i386"
OriTyp = "4"
LocalSourceOnCD = 1
DisableAdminAccountOnDomainJoin = 1
 
[SetupData]
OsLoadOptions = "/fastdetect"
; Needed for first stage
SetupSourceDevice = "\Device\LanmanRedirector\SAMBA_SERVER_IP\tftproot\winxp"
 
[UserData]
ComputerName = *

Editing the pxelinux.cfg/default boot menu

Edit your boot menu so that it contains the following entry:

LABEL WinXP
	MENU LABEL Install MS Windows XP
	KERNEL winxp.0

Re-Start all required daemons

If the daemon isn't already running use start instead or restart in the following commands

/etc/init.d/dnsmasq restart
/etc/init.d/in.tftpd restart

Modify Binlsrv, update driver cache, and start driver hosting service

Change the BASEPATH= variable at or around line #62 of binlsrv.py so that it is:

BASEPATH='/tftproot/winxp/i386/'

Generate driver cache

cd /tftproot;./infparser.py winxp/i386/

Start binlservice

./binlsrv.py

Booting the client

If all is well, you should be able to boot the client choosing to boot from network in the boot options, you should get to your PXELinux bootloader, and see the Install Windows XP option after pressing enter you *should* kick off your XP installation via network!! Congratulations!
