Install Dos 7.1 To External Hard Drive

Back in the days when floppy disks were still being commonly used, flashing your motherboard’s BIOS could only be done by booting the computer into DOS. When DOS is booted up on the computer, you’d probably have to switch to the floppy disk that contains the BIOS update file. Unlike today where updating a modern BIOS is far easier and convenient and you can update the BIOS directly from Windows using the software provided by the manufacturer, or simply put the BIOS file onto a USB flash drive and the inbuilt flashing tool inside the BIOS will recognize it.

If for some reason the software provided by the motherboard manufacturer is broken and you’re not able to update the BIOS from Windows, or your BIOS doesn’t actually support flashing from any other medium apart from a floppy drive and DOS, you can still do it from DOS by booting up the computer with a USB flash drive instead of a floppy which is far easier. The most popular and easiest ways are to simply install MS-DOS or FreeDOS onto the USB drive, copy over the required BIOS file and flashing utility from the manufacturer’s website, boot to USB and flash the BIOS from there.

Thankfully, there are tools around that can help you accomplish this with the minimum of effort, and not lead you through a huge multiple step process full of manual commands. Here are 5 such tools that will put either FreeDOS or MS-DOS onto a bootable USB flash drive allowing you to update the BIOS firmware from DOS but without a floppy drive.
