Can't think of any.

DOS files are in the boot directory of the directory you unzipped this to...

Pros
None for the moment.
Cons
Couldn't run the application

Pros
easy to use, very handy software for nowadays. since no laptop has floppy drive
Cons
No MD-DOS file included in the software package! Where can I get the DOS files? I couldn't find MS-DOS files on Win7!
Summary
Does what I needed it to do.

I found none.
Summary
Great Tool
assmanMarch 29, 2011
Pros
Easy setup All the files you need to boot into DOS Helpful instructions Provides DOS without floppy
Cons
Wish I found this sooner
Summary
Thanks so much for this tool. I used it to configure Intel's LAN boot agent, which only works in DOS. Tried everything else before this simple solution.
No mention of NON-SATA AND NON-NTFS (FAT) program only!
JayDubThaHackerOctober 27, 2010
Pros
I suppose I should give it 2 stars because I used it (maybe??) years ago to access some old PC. I remember it sort of working. IT DOES BOOT INTO DOS, and it does warn you not to use it if you have an NTFS Windows setup. So I got UltraBootCD instead..
Cons
Literally, this is useless to anyone with SATA, ATA, hardware drives and/or NTFS (2000,XP,Vista and 7 typically use this system) harddisks. FAT and IDE only are supported by this program. I've tried several times. So this will soon be like ZIP disks.
Summary
Useful for IDE and FAT systems, thanks James. Useless for any others. C+
Works exactly as described

Pros
If you just need to boot just format the usb drive with the executable. If you need DOS follow the instructions carfully.
Cons
Not really.
Summary
Great if you just need a bootable USB drive. You need to get repair and diagnostic utilities elsewhere.

Developer’s Description

By Jamesonline

Install MS-DOS 7.1 on your USB memory key.

DOS-on-USB lets you install MS-DOS 7.1 on your USB memory key. After formatting your flash drive, you can install a full working version of MS-DOS to let you run games or system utilities. The best thing about having a DOS-bootable memory key is you can boot into it on any computer, just like a CD.

You'll find this utility great for times you need to do system maintenance, because you wont constantly have to burn a new CD, just copy the program to the USB Drive. With the DOS prompt, you can even install Windows 95 or 98. Recommended USB drive size: 16MB - 2GB. Version 2 features an auto launch for ease of the DOS operating system.
