RIS for Linux - Boot winpe from the net / Ris Windows Installation

A new pdf guide written from scratch it's available on the main page

This document describes how to setup an opensource (Linux based) alternative to windows ris
You can also use this stuff to install windows from the net

Required software:

Required Stuff:

ris-linux contains following files:

TFTP Server

Download atftpd apply the patch, compile and install it, you can configure it using inetd, by adding the following line:

tftp dgram udp wait nobody /usr/sbin/tcpd /usr/sbin/in.tftpd /tftpboot

If you are using hpa tftp server apply the respective patch and recompile it. The author suggested me to run hpa tftp server standalone without using inetd, because inetd support is broken and hpa tftp can directly handle tcpwrappers.

Please note that filecase lookup doesn't work (at least for me) when having links in the path, I suppose this is a security measure, or maybe the linked path should be in the chroot. Anyway this is not related to my lookup patch, if you are using hpa ftpd you should known how it works :)

DHCP: bootp

Assuming the tftpd and dhcp/bootp directory is /tftpboot, we need to have following files:

All files should be in the root of tftpd directory.
Take care of case since files must have exactly the case used in this document
pxelinux.cfg/default is a standard syslinux file you can use this simple one:

TIMEOUT 0
PROMPT 1

label xpe
    kernel startrom.0

DHCP Server configuration

Edit dhcp server configuration, in my distro is /etc/dhcp3/dhcpd.conf
Configure the server this way:

subnet 192.168.129.0 netmask 255.255.255.0
{
  range dynamic-bootp 192.168.129.100 192.168.129.110;
  default-lease-time 600;
  max-lease-time 7200;
  filename "pxelinux.0";
  server-name "attila.of.war";
  next-server attila.of.war;
}

Replace attila.of.war with your dhcp server name, also use startrom.0 instead of pxelinux.0 if you don't want to use pxelinux.

Samba configuration

Make your build without iso and copy the contents of pebldr directory in a suitable place, a good choice is to name the directory ris and rename pebldr folder to winpe.
The directory structure should be ris/winpe/i386..., also you need to put a symbolic link in /tftpboot pointing to winpe directory. If your tftp server doesn't allow symbolic links you should put the directory on the top of your tftp server root.

An example configuration for samba:

[REMINST]
     path = /mnt/disk/ris
     browsable = true
     read only = No
     guest ok = Yes

You must set null passwords = true in smb.conf.

You also need to modify server name and path in SetupSourceDevice option of winnt.sif file.

Edit the path in fixup-repository.sh and launch it to fix case of needed files.
Note: you don't need to fix names if you are using my new atftpd patch.

Binl Server

First you need to build device driver cache using infparser.py, e.g. infparser.py /mnt/disk/ris/winpe/i386/inf, this will create devlist.cache file that must be in same directory of binlsrv.py.
Now you can launch binlsrv.py, it will load the driver cache and will reply to client requests.

./binlsrv.py
Succesfully loaded 662 devices
Binlserver started...

Then start the client and boot from network, at pxelinux prompt enter xpe, the client will start and if all is ok binlsrv.py should receive a driver request:

Recv NCQ len = 48
NCQ Driver request
[R] Vid: 0x1022
[R] Pid: 0x2000
[R] rev_u1 = 0x2
[R] rev_u2 = 0x0

[R] rev    = 0x10
[R] rev2   = 0x88
[R] subsys = 0x20001022

[S] BusType (REG_SZ [1]) = 5

Finally if xpe starts but tcpip network will not work, windows shares are ok, any solution?

Windows RIS installation from the net
If you want to use windows remote installation service you should use winnt-ris.sif and rename it to winnt.sif, you can setup both xpe from pxe and windows installation by renaming ntldr and winnt.sif and hex-editing the files, I'll add an howto soon for this. Also make sure you have files in the path specified in winnt.sif.

Note: Right now windows installation from the net works only if bypassing all ris stuff, so you'll not able to use OSChooser.
A detailed description about configuring this can be found here.

Note: if your card doesn't support network boot you can use a floppy image made with Rom-O-Matic, part of Etherboot project. You need at least a version 5.3.8 image to support pxelinux, the etherboot-pci with all drivers doesn't compiles yet, you must wait some time. Select Floppy bootable ROM Image (.zdsk), default options are ok. Write it with RawriteWin from windows or using cat image.zdsk > /dev/fd0 from Linux.
There is also a tool shipped with Windows Server named rbfg.exe that makes similar floppy images but it doesn't support all cards supported by etherboot.

I've made a driver with support for most common nics, compiled drivers: 3c90x 3c595 eepro100 e1000 ns8390 rtl8139 tg3 tulip pcnet32 via-rhine forcedeth sis900 etherboot.zdsk
