RawWrite is pretty much self explanitory. Just save it to the directory that you made earlier and rename the file if necessary.
COMPILING BOCHS PASSWORD
Be sure to select All files when you save the image and don't password protect the image or it will be written in the wrong format: Once it is finished you need to save the floppy image. Then, insert your floppy into the first floppy drive and select Disk -> Read Disk. Copy 1.44 to the directory where the Bochs configuration file is. This instructs PartCopy to copy the entire floppy and to put the data in a file called 1.44(which you will find in the same directory as PartCopy once you do the above). Just insert your floppy into the first floppy drive and run PartCopy with like this: partcopy -f0 0 168000 1.44 The first is to go get WinImage(sharware, 30-day trial, costs $30(US) for standard or $60(US) for professional). An image is simply every single bit and byte of a disk put into a file. Once that's done, we need to make an image of it. Now it's time to make a floppy disk image! Making a Floppy Disk Imageįirst, start by copying your bootsector and kernel to a real 1.44MB floppy(this tutorial assumes that the floppy is FAT12 formatted).

Second, we need to make a configuration file called bochsrc.txt in the directory that we just created. In my case, I'm going to create a new directory called OS dev inside the Bochs' directory. Okay, let's set up bochs to boot from an OS that is on a floppy disk.įirst, we need a new directory that's inside the Bochs' directory. Setting Up a Bochs Configuration File for a Simple OS Now you need to create a configuration file for Bochs. Then, simply unzip Bochs to the desired directory.
