Or you can use grub.exe to map an image to a floppy device and re-start DOS. Or, even better with one of the "lesser known" companion apps to SHSUCDX: You need anyway to experiment if that works with a "mounted" image, such as one from Frank Uberto's XMSDSK: Let me know if you have any other questions and I'll be happy to try and clarify further. from a bootloader such as grub/grub4dos/syslinux)Ĥ. I don't need to write the created IMG file to floppy I just want to be able to create the image file so I can copy it back to my USB stick or otherwise access it on the hard drive later (e.g. create a 1.44MB floppy disk IMG file from source files additionally I'd like to be able to create arbitrarily sized IMG files, but a boot floppy image (1.44MB) is sufficient to start (I've succeeded in creating bootable hard drive image files which I can boot to, but only using BSD or Linux and I want to be able to create the bootable images from within DOS)ģ. I have some DOS floppy image files and HD image files which I currently boot from using grub4dos)Ģ. Boot from a hard disk OR from an image file (on a USB stick) to DOS (e.g. I found this thread from searching and was hopeful it would provide a solution, but I think the ideas in here relate to creating an image file from an actual floppy, not from files on the hard drive:Īnyone know how I can accomplish my goal?ġ. mkbt, etc.) but sadly they do not seem to work in real-mode DOS, only in a DOS-shell within Windows. I saw some of Bart's tools which looked promising (e.g. I guess I need something like mkisofs for DOS, but a tool which will create a floppy image file instead of an ISO-9660 file. I don't believe tools like rawrite or dd will work because they don't specify a set of files (or a directory) as a source. dosboot.img - 1.44MB) using files from my DOS environment as the source.Ĭurrently I can create bootable DOS images fine from within Windows using WinImage or similar tools, but I want to be able to create these images from within DOS because it will be much more efficient than going back and forth between DOS and Windows to do my boot testing and image creation and modifications. What I'm trying to do is from within DOS create a bootable DOS image file (e.g. I'm hoping someone can provide a solution or point me in the right direction.
