1/open ubuntu.iso in winrar or 7zip (or any other iso reading capable tool).

2/launch winnfsd with the following :
winnfsd.exe -id 0 0 x:\pxe\iso\ubuntu.13.04
note : adapt the above path with your own path
3/use the below ipxe script :

Latest version 1.0.0.14 now support ProxyDHCP features.
In short :
TinyPXE Server can now co exist « peacefully » with another dhcp server on the same LAN.
No more race conditions where first one (dhcp server) to answer wins the lease.
With ProxyDHCP option enable, TinyPXE Server will now « only » provide the boot file name information (and only to proxydhcp clients) : the client will then use/combine the dhcp offers from both servers (lease+boot file name).
Tested with success with the following boot straps : ipxe , gpxe , pxelinux , startrom.0 , pxeboot.com …
Discuss it here at reboot.pro.
More info around PXE here.
Cheers,
Erwan

A quick article around my adventures with the Arduino.
This time, lets play with infrared.
More precisely lets catch IR signals and send them back.
The IR sensor can be found here.
The IR emitter can be found here.
You can use 2 arduino or built it all on one arduino (if so, add a object.enableIRIn() after each send or you wont be able to receive after the 1st send).
Here below the wiring and a quick and dirty sketch for sending.
Now go and place with your remotes !
Sketch to send signals with your IR emitter.
/* * IR LED must be connected to Arduino PWM pin 3. */ #includeIRsend irsend; void setup() { Serial.begin(9600); } void send(int code) { for (int i = 0; i < 3; i++) { irsend.sendNEC(code, 32); // code, length delay(40); } } void loop() { send(0x11223344); delay(5000); }

Agenda
- Prepare winpe (3 or 4) with QuickPE
- Prepare the ipxe script
- Prepare the PXE server with TinyPxe Server
- Prepare the ISCSI target
- Boot to winpe, prepare the drive, and Install windows
- Reboot to your target !
Note that we have already covered installing win7 (or win8) directly to an ISCSI target : here.
However, there are times where yoy may not have a dvd drive or media available, or else, you may also want to perform some tasks before triggering the windows setup.
Prepare winpe (3 or 4) with QuickPE
You can either use MS WAIK (winpe3), or MS ADK (winpe4) or an existing windows setup DVD or ISO file.
Launch _run_me.cmd and make your choice.
Prepare the ipxe script
The following will attach an iscsi drive and will boot your winpe
#!ipxe
dhcp net0
set gateway 0.0.0.0
set keep-san 1
sanhook iscsi:192.168.1.248:tcp:3260:0:iqn.2000-01.com.synology:test
set boot-url http://${dhcp-server}
initrd ${boot-url}/images/winre.iso
kernel ${boot-url}/memdisk iso raw
boot
Prepare the PXE server with TinyPxe Server
Use ipxe-undionly.kpxe as « boot file name » and the above script (name it install.ipxe) as « filename if user-class=iPXE »
Prepare the ISCSI target
There you can either use starwind target free edition or any other target (many home nas device do have that feature also).
The target should be at least 8GB.
Boot to Winpe, prepare the drive
Now lets network boot (pxe as first device in the bios).
Computer will pxe boot, load ipxe, then load your script.
The script will atatch your iscsi target and boot into winpe.
Note : you need one physical disk in your computer or else winpe might reboot in a loop. Also the windows setup will not go pass the disk selection if not physical disk is present.
Once in Winpe you should see your iscsi target listed as a physical drive : to check this, launch CloneDisk or diskpart.
Fist, lets create a disk, then lets create a (active) partition and finally lets format it : you can do all this with CloneDisk or diskpart.
Then Lets also take care of the MBR and BS either with « bootsect.exe /nt60 c: /MBR » or with bootice or with CloneDisk.
Finally lets also create the bcd store with the following « bcdboot x:\windows /s c: ». C: is your iscsi disk, X: is your winpe disk.
Another alternative is to copy the bcd folder and the bootmgr file from your dvd to your target drive.
Then edit c:\boot\bcd with bootice or bcdedit and add a default win7 entry.
Now we are ready to perform the installation : map a drive thanks to PeNetwork (in the tinyshell launchbar) and either map a dvd shared over the network or an iso found in a network share.
Note : CloneDisk can also mount a virtual dvd driver from an iso file (only in winpe4).
Launch the windows setup and let it run : you should find your iscsi drive there.
Boot to your ISCSI target via PXE
Here comes your second ipxe script, name it boot.ipxe and use it within Tiny PXE Server :
#!ipxe
dhcp net0
set gateway 0.0.0.0
set keep-san 1
sanboot iscsi:192.168.1.248:tcp:3260:0:iqn.2000-01.com.synology:test
Windows should the complete the installation, and reboot one last to your windows desktop.

Here below the different steps to backup or clone a (physical or logical) disk (hosting any operating system) using WinPE and CloneDisk.
1.Getting tools
First, lets get the needed files and prepare our working folder :
QuickPE and unzip it to x:\quickpe.
CloneDisk and unzip it to x:\quickpe\extra
2.Preparing
Now, lets prepare our WinPE iso
Generate your WinPE iso using any of the option that suit you best : use WAIK or ADK or your sytem WinRE or a DVD or an ISO …
3.Booting
At this point, you have an iso file in x:\quickpe\x86 named winxx.iso.
you can either burn it to cd/dvd (easiest path),
« burn » to a usb stick with rufus
or (more complex) boot it thru pxe (using these guides).
4.Networking
This step is needed only if you intend to backup your drive to an image file over a network drive.
Once booted, ensure you have a correct network setup using PeNetwork : click on the info button.
Provided, you have a network connectivity, then map a network drive, still using PeNetwork.
5.Backuping
Now, launch clonedisk from x:\extra folder, choose your source drive and either back it up to your network drive or clone your source drive to a new target drive.
