There are a millions answers to this question, and I have found non that answer this detail about no B drive. The cool thing even before 3 1/2 inch disks, is you could just have 1 floppy drive and still be able the copy from one floppy to another. The B drive can work as a virtual drive. If need to copy somehting and had only one drive, you would issue a copy command and it would hold the information you want to copy on a virtual B drive. Place the original in, "copy to b drive" take out the original and put in a blank and it would copy the files to your B drive. This we found was always a cool tool. No need for a second floppy drive.
There are several steps that need to be followed in order to change the drive order on a computer. First, go into the BIOS and press whichever button opens the menu. Go to the boot tab, then set the floppy drive as the second drive, or drive b. Finally, save the selection, and start the computer.
