I was playing around with an OS-development tutorial here. However, as it is based on Windows as the development platform, I was wondering if there is an equivalent software (or some way) to have a virtual floppy drive.
The virtual floppy drive only seems to be used in that tutorial in order to create a virtual disk that Bochs can boot off of. Linux is actually more flexible in this regard. What you'll need to use is a loop device. How to use this with Bochs, I don't know - you'll need to read the documentation :)
