As a device for personal computers to exchange data, the floppy drive is the component that has changed the least in the history of personal computer development. As people have higher and higher requirements for the portability of information, its defects such as small capacity and easy damage have made it increasingly difficult to meet the needs. The bootable USB flash drive can be used as a system boot disk to directly boot the computer system, thus realizing all the functions of the floppy drive and can completely replace the floppy drive as the standard configuration for computer data exchange; at the same time, the maximum capacity of the USB flash drive has also expanded from 1GB to 2GB, which can meet the mobile storage needs of various industries.
The bootable USB flash drive complies with the USB 1.1 standard, has its own driver program, and can be directly used on operating systems such as WinMe/2000/XP, MacOS 9.x/MacOS X, and Linux 2.4.x, eliminating the trouble of installing the driver program and realizing true plug-and-play.

Under DOS, go to the drive letter of the USB flash drive, enter the corresponding directory and execute the corresponding program.
4. At this point, you have already had a USB flash drive that can boot the DOS system.
5. Insert the USB flash drive into the USB port (it is best to temporarily unplug other USB devices), restart the computer, press the Del key to enter the BIOS setup on the system self-test interface (if it is a special BIOS, please refer to the motherboard manual to determine which key to press to enter the BIOS), enter BIOS FEATURES SETUP, set Boot Sequence (boot sequence) to USB-HDD first. The method of setting is to press the PageUP or PageDown key on this item to convert the options.

6. After the system restarts, it will automatically boot the DOS system from the USB flash drive. There are 3 options in the boot menu:
boot dos with cdrom is to drive the optical drive,
boot dos with cdrom + usb is to drive the optical drive and USB flash drive,
boot dos only only starts DOS and loads memory management and smartdrv high-speed cache.
Use the ↑↓ keys to select the boot mode you need and press Enter to confirm. It should be specially noted here that if you select the boot dos with cdrom + usb item, there will be a relatively long pause (1-2 minutes or so) when scanning USB devices during the boot process. Don't think it is a system crash, just be patient and wait.
7. After a successful boot, the words DOS LOADING SUCCESSFUL will be displayed and it will be at the A:\> prompt. At this point, the DOS system has been successfully booted, and now you can do what you need to do.
Precautions: Please back up the original data on the USB flash drive before making the boot disk, and it is best to fully format the USB flash drive.

我完全同意设想建立DOS组织“DOS联盟” ，也就是说和Wengier、以及“起步”站长莫老师等DOS战友一起来建立这个“DOS联盟”，以发展我国自主OS（操作系统）的高度去完成我们共同的愿望。
