Quick Hack: Make a MSDOS Bootable USB drive… with Virtualbox?

by on Jun.29, 2019, under How-To's, Miscellaneous, Quick Hacks

To set the scene for this quick hack, I needed an MSDOS bootable USB drive so that I could flash firmware for a FreeNAS box I was building. Infortunately FreeDOS wasn’t working, unetbootin had failed me, and I was getting desperate. Fortunately VirtualBox to the rescue!… wait, what?

  • Install Virtualbox
  • Acquire a MSDOS .iso from the Internet (they’re out there.)
  • Create a new VM with a 500MB hard drive.
  • Attach the MSDOS iso to the VM and boot it
  • Depending on which MSDOS iso you have, you will need to partition and format the C: drive. Use fdisk to partition the 500MB drive (don’t forget to set it bootable) and then use format c: /s to format the 500MB drive as bootable. Perform the MSDOS installation or copy the DOS directory from the ISO.
  • Shutdown the VM
  • Locate the .VDI for the VM and use VBoxManage to export it to raw: VBoxManage clonehd image.vdi image.img –format raw
  • Use a tool like dd, rawwritewin, or imgburn to write the image.img file to a USB key.
  • Upon successful write, remove then reinsert your USB key. Your machine will mount it as a typical USB drive (Windows/Linux/Mac all behave the same in this regard).
  • Copy over the BIOS flashing utilities, RAID flashing utilities, etc. to the key drive.
  • (Optional) You can also create a \efi\boot directory and place a uefi boot file in there if you need it as well.
  • Eject the USB drive, then boot your target system. The USB disk will show up as drive C:.

The secret sauce is the VBoxManage command. It allows you to export a Virtualbox Disk Image (VDI) to a raw image that can be written to a USB disk. Now you have a solid MSDOS installation on a keydrive for all those damned ROM flashing utilities that will only work in DOS!

Happy hacking!

Site News: Quick Hacks category

by on Jun.29, 2019, under Miscellaneous

Between work and life in general, I haven’t had much time to come up with really noteworthy long posts like I’ve been. It’s been several months since my last post about Cruising with Wi-fi, and a year between that and the previous post.

In an effort to try and produce more content for my site, while not putting too much a damper on work and life, I’ve decided to create a new post category called “Quick Hacks”. This category will be reserved for quick little things that I’ve encountered that are noteworthy, but previously didn’t justify their own full-length post. Now, the category “Quick Hacks” will give these hacks, mods, experiences, and ah-ha moments their own spotlight where they belong.

To my adoring fans (all 142 of you according to the FB page), thank you for hanging around. Here’s to this site’s continued success!

Thank you.

Defcon 25 Title Image

Yes, it’s faded. I took this pic from a projection standing about 50ft away.

Good fortune has smiled upon me.  My company offered to send me to DEFCON 25, flight and hotel paid.  In this article, I’ll talk about DEFCON 25, the sights, the sounds, and my experiences of a hardware geek gone to the world-renowned hacker mecca. If you have ever wanted to go to DEFCON but aren’t quite sure what to expect, I have provided a summary of the trip as well as an important “FNG TIPS” list of things you want to be aware of before you leave.

New threat to sobriety: Arduino powered JagerBomber costume!

Arduino powered Jagerbomber!

Arduino powered Jagerbomber! (click to zoom)

The challenge for this year’s Halloween party was to find a “B-rate” superhero or villan.  No superman, spiderman, ironman, or other mainstream nonsesne here. We had to come up with something unique and not-mainstream, so my answer was clear.  I present to you the Arduino powered Jagerbomber, complete with countdown timer. This costume served me quite well, winning both the party’s “Best Male Costume” and later on at work, “Best Costume” so I’m sure it’ll give you some good ideas for next year!  Remember, only 363 Days till Next Halloween!

I know it’s been a while since I posted, and I do apologize.  Life has definitely not been kind to me in the regards of time however I have not forgotten anything. I have two major posts coming up hopefully within the next week, however here’s a quick article about a trick I discovered while working on a project with a friend.  The project was to see if their content filter could be broken in their chat application andthrough a little bit of HTML know-how and some PHP code, I was able to crank out a generator to do just that.  Read more to find out the details.

Welcome to the inaugural post of YourWarrantyIsVoid.com.

It has been a rough couple of months with the site migration to the new server, but I’m hapy to say that the migration was a success.  New tools have helped me completely overhaul the YWIV site into something that at least looks like it was coded in this century.  Read more to find out what all I have in store for this site.
