In my quest to get a balloon into the Stratosphere, I ran across a few teams using Arduino boards to operate payload functions and some that used the Digi Xtend RF modules for communication. I bought both!

Let’s face it, the best USB thumb drive will boot on it’s own into it’s own operating system or specialized utility. Those are the thumb drives that save the day! Of course, if you have a thumb drive that boots into a drive imaging utility that really does you no good at all if you need to do a virus scan. That’s where Multipass (Multiboot) USB comes in.

Here’s how it works:

Every bootable drive has a set of instructions at a certain place that tells the computer how to load and run what’s on the drive. Normally, these set of instructions tell the computer to load Windows, OS X, DOS, Linux or whatever type of system you’re using. With the addition of a “Boot Manager”, the drive tells the computer to load the boot manager the same way – except the boot manager can now give you a selection of what you want to boot your computer into. Boot managers have been around for a while, but making their way onto USB drives is relatively new.

OK, so what’s the plan? What are we going to do with this USB Drive? I have several tools I consider “favorites” and we’re going to combine them all on one USB thumb drive. Here they are and what they do:

Trinity Rescue Kit – “Trinity Rescue Kit or TRK is a free live Linux distribution that aims specifically at recovery and repair operations on Windows machines, but is equally usable for Linux recovery issues.” - Trinity is my newest favorite tool. It resets passwords, runs virus scans from 4 different vendors, rootkit detection, filesharing, drive evacuation – you name it. It’s a very thorough tool.

Kon-Boot – “Kon-Boot is an prototype piece of software which allows to change contents of a linux kernel (and now Windows kernel also!!!) on the fly (while booting). In the current compilation state it allows to log into a linux system as ‘root’ user without typing the correct password or to elevate privileges from current user to root. For Windows systems it allows to enter any password protected profile without any knowledge of the password.” - It does exactly what it says it does. very well and damn near seamless.  Fantastic for Forensics and getting back into machines that you’ve long forgotten the passwords to.

Ophcrack – “Ophcrack is a free Windows password cracker based on rainbow tables. It is a very efficient implementation of rainbow tables done by the inventors of the method. It comes with a Graphical User Interface and runs on multiple platforms.” – As the one in charge of IT security, it’s my job to make sure your passwords are secure enough. This fantastic tool will tell me who passes and who fails the test!

DBAN - “Darik’s Boot and Nuke (“DBAN”) is a self-contained boot disk that securely wipes the hard disks of most computers. DBAN will automatically and completely delete the contents of any hard disk that it can detect, which makes it an appropriate utility for bulk or emergency data destruction.” - With a government IT background and my current position having to rely on HIPAA guidelines, DBAN is a great tool to wipe a computer’s hard drive to Department of Defense specs.

Hiren’s 9.9 – Hiren’s Boot CD is the standard by which all other Rescue CDs are measured. This CD has an amazing amount of stuff on it. It was my #1 go to CD for a long time.

Ubuntu 9.04 LiveCD - “Ubuntu is a community developed, Linux-based operating system that is perfect for laptops, desktops and servers. It contains all the applications you need – a web browser, presentation, document and spreadsheet software, instant messaging and much more.” – If the machine won’t boot at all and you NEED to get into an operating system for something, an Ubuntu LiveCD will save the day.

Windows 7 Install DVD – Windows 7 is going to be a hit. I’ll be prepared with the ability to install it from a USB drive as well as boot into the recovery mode to solve problems.

BackTrack 4 - “BackTrack is the most top rated linux live distribution focused on penetration testing. With no installation whatsoever, the analysis platform is started directly from the CD-Rom and is fully accessible within minutes.” - Again, as a security professional, I need to know when my systems are vulnerable. This amazing set of applications allows me to attack my systems and find their weak points.

Macrium Reflect - “A complete disaster recovery solution for your home and office. Protect your personal documents, photos, music and emails. Upgrade your hard disk or try new operating systems in the safe knowledge that everything is securely saved in an easily recovered backup file.” - Time for a new hard drive? Boot into Macrium for a fast way to clone your existing data to your new drive. It’s today’s Symantec Ghost.

Let’s begin!

There are three tools you’ll need to pull this off – PeToUSB, grubinst and grubfordos. Format the USB drive with PeToUSB by selecting the drive and choosing: Enable Disk Format, Quick Format and Force Volume Dismount. If you have a drive thatps over 2GB, you’ll get an error. Ignore it and format the drive as FAT32 using Disk Manager in Windows. Next, run grubinst_gui.exe from the grubinst package. Select your drive and click install. No options need to be changed. Copy the grldr file from the grubfordos package and place it into the root of your drive. Finally, create a text file called menu.lst and place it with the grldr file. You can now boot from the USB drive. You’ll quickly find out that at this point, there’s nothing to boot into except the bootloader! Time to put your goodies on the drive.

From what I understand, the next version of grub will give you the ability to multiboot directly into an ISO image of a CD or DVD more reliably. As of now, there are only a few ISOs that this will work with. Let’s go through some examples of my configuration.

Hiren’s BootCD: One of the easiest to set up. Simply extract the contents of the ISO and copy the HBCD folder to the root of your USB drive. Edit the menu.lst file and add the following:

title Hirens 9.9
kernel /HBCD/memdisk
initrd /HBCD/boot.gz

You’ll now have the menu option to boot into Hiren’s Boot CD. It gets tricky though. Let’s take a look at Ubuntu LiveCD. For this one to work, we need to extract the entire contents of the CD to the USB drive. Our menu entry for it would look like this:

title Ubuntu 9.04 x86
root (hd0,0)
kernel  /casper/vmlinuz boot=casper ramdisk_size=1048576 root=/dev/ram rw quiet splash
initrd  /casper/initrd.gz

It takes a little trial and error to get things working the way they should, but the payoff in the end is worth it. What about Ophcrack and other BootCDs that contain “BOOT” folders? If you copy all the BOOT folders to one location, won’t they screw everything up? Yes they will. What we will do is put them either in subdirectories or rename the BOOT folder to something like “Ophcrackboot” once they are on the thumbdrive. Here is my Ophcrack entry:

title Ophcrack
kernel /ophcrack/boot/bzImage rw root=/dev/null vga=normal lang=C kmap=us screen=1024x768x16 autologin
initrd /ophcrack/boot/rootfs.gz

Finally, here is my entire menu.lst for my Multipass USB drive:

splashimage=/splash.xpm.gz
color red/black white/black

root (hd0,0)

title Ubuntu 9.04 x86
root (hd0,0)
kernel  /casper/vmlinuz boot=casper ramdisk_size=1048576 root=/dev/ram rw quiet splash
initrd  /casper/initrd.gz

title Windows 7
map (hd0,0)/win7.iso (hd32)
map –hook
chainloader (hd32)

title Trinity Rescue Kit
configfile /submenu.lst

title Hirens 9.9
kernel /memdisk
initrd /HBCD/boot.gz

title Macrium Reflect
map (hd0,0)/macriumreflect.iso (hd32)
map –hook
chainloader (hd32)

title Kon-Boot
map –mem /konboot.img (fd0)
map –hook
chainloader (fd0)+1
map (hd1) (hd0)
map –hook
rootnoverify (fd0)

title Ophcrack
kernel /ophcrack/boot/bzImage rw root=/dev/null vga=normal lang=C kmap=us screen=1024x768x16 autologin
initrd /ophcrack/boot/rootfs.gz

title ntpasswd
kernel /ntpasswd/vmlinuz rw vga=1 initrd=/ntpasswd/initrd.cgz /ntpasswd/scsi.cgz
initrd /ntpasswd/initrd.cgz

title BackTrack 4 BETA
root (hd0,0)
kernel /bootbt4/vmlinuz vga=0×317 ramdisk_size=6666 root=/dev/ram0 rw quiet
initrd=/bootbt4/initrd.gz
boot

title DBAN
kernel /memdisk
initrd /dban.img

title Boot the First Hard Disk
rootnoverify (hd1)
chainloader +1

So what does it all look like when it’s finished? I’ve added a custom background to my installation and you can too. read the documentation for grub4dos to find out how – it’s super simple. Now for the eye candy!

First off, let me first apologize to the vintage TV purists out there. I know there are very few of these televisions left out there and most aren’t as nice looking as this TV. Parts are hard to find and even if I did revive it, even though it’s nostalgic, I wouldn’t enjoy watching it every day.

I bought the TV a couple of years ago at an auction just because I loved the way it looked. When I got home, I plugged the TV in hoping to see an image on the screen but was instead met with a blank screen but fantastic sounding audio. I was slightly disappointed, but what do you expect for a as-is, where-is sale? I shuffled it into a spare room where it sat for all that time. As you can see from the picture to the right, it was a TV, but also a TV stand in itself! That’s no way for a classic RCA to live…

I started looking around for a tube 4:3 TV that I could house in the RCA cabinet that preferrably had HD abilities. Sadly, my search to find the right picture tube never panned out. I wound up waiting too late to search and now all the store shelves are loaded up with widescreen LCDs. You’re lucky if you can find a tube TV now. Seeing the state of things on the shelves I decided to drop the tube TV idea and move on the replacing the tube with an LCD.

In my Multi Touch table project, I’m using a Dell 23″ widescreen LCDso I grabbed it and laid it up against the RCA’s screen. Hmm… with a little bit of modification, I can put the widescreen LCD in there!

Let the hacking begin!

I started out by removing the guts of the TV. As you can see in the picture to the left, it had a lot of guts! Heavy, too.

While playing mad scientist in the back of the TV, I found a ring on the tail end of the TV tube that had broken loose and was just flopping around. That’s probably what the problem was, but I was on a mission!

I removed everything you see in the photo, the mass of tubes on the bottom of the cabinet, the tuning assembly on the left and the picture tube itself.

Once the case was gutted, I took the tube fascia off and marked where to make the cuts so the LCD panel would fit. I had hoped to leave a few of the original tube support mounts to use to secure the LCD, but due to it’s width they had to go.

An air powered auto body saw made very short work of the heavy duty steel that the fascia was made of. It cut through it like butter. I was able to cut right up to the tape line nice and smooth without even disturbing the tape!

Once I had the fascia trimmed, I dropped the LCD into place to make sure everything would fit. It fits like a glove!

Since it was rather late at night to go parts shopping, I grabbed a few lengths of wire, some electrical tape and an old pair of black slacks I’ve never worn and put them to use.

I strapped the LCD to the case with the wire and cut strips from the slacks to lay over the top and bottom edges of the LCD to act as a blackout cloth since the fascia and the LCD don’t mate up completely.

I had planned on making a run to Lowes to pick up something proper to strap the LCD in with, but it is Mother’s Day after all. I’ll stop by the hardware store sometime this week and finish up the LCD mounting.

I’ve still got a little bit of work to do with this to be complete. Here’s a short list:

• Set up the dedicated PC. It will be a Dell Dimension 4700 2.8GHz machine. Needs a video card upgrade first.
• Mount the IR remote control receiver. This should be pretty straight forward.
• Mount an external DVD writer in the case. See that funny looking panel with the “RCA Victor” and chevron on it? That’s a flip down access panel. The drive is going behind that!
• Audio. I need to do something about sound. I’m thinking a small amp to drive the stock speakers. They sound awesome!

After all of that, the RCA Victor Media Center should be complete! Here’s a few more shots showing the finished product. I’ve succeeded in turning a vintage 1957 Console TV into a high definition media center capable of playing 1080p content for just about $300!
