How to boot DexOS from a USB stick

First thing you will need to download DexUsbBoot in this zip you will find one format program to format the usb FAT (fat16), and a program to put the DexOS + app on a usb drive, so as to boot from it as Fdd or Hdd emulation.
Here some important things to remember, first for safety, you need to format the drive fat16, using the program included with this zip called "usb_format.exe", as window does not format it, as we need it.
If you do not format it as fat16 (FAT in the program), the program will not put DexOS on the drive.
Once formated, put your usb drive in a usb port, click on the UsbDex program and check its got the right drive, then click for Hdd or Fdd for the emulation (Try Fdd first).
Then click to write it to the drive, under Fdd emulation all the files (including app) are put on the drive as a floppy image.
But if you chose Hdd emulation, it will ask if you want to put the kernel32 + app on, click Yes. Then once its finished you ready to reboot.
Note: Once it finish loading the app you many need to click on the program in the task bar.

Once you reboot press F11 or F12 (or what ever you pc need to go to boot menu) and click on the USB ????, some pc do not have a boot menu and you need to goto the BIOS to check boot order, make sure USB drive is first.

Now the thing to do first if you do not know if your pc/laptop users fdd or hdd, is to try the FDD emulation first only use HDD if fdd does not work.
Thanks for trying DexOS on USB.

PS: If you chose FDD emulation the drive will be reported as the same size as a floppy, just reformat it to get the full drive size back once you have test it, also note: some PC only boot from certain usb port so try more than one port, if it does not boot.
