This makes it possible for the operating system, once booted, to use the remainder of the device for persistent storage by creating a second partition. - - - ++++ BOOTING DOS (OR OTHER SIMILAR OPERATING SYSTEMS) ++++ - -WARNING: This feature depends on BIOS functionality which is -apparently broken in a very large number of BIOSes. Therefore, this -may not work on any particular system. No workaround is possible; if -you find that it doesn't work please complain to your vendor and -indicate that "BIOS INT 13h AX=4C00h fails." - -To boot DOS, or other real-mode operating systems (protected-mode -operating systems may or may not work correctly), using ISOLINUX, you -need to prepare a disk image (usually a floppy image, but a hard disk -image can be used on *most* systems) with the relevant operating -system. This file should be included on the CD-ROM in the /isolinux -directory, and have a .img extension. The ".img" extension does not -have to be specified on the command line, but has to be explicitly -specified if used in a "kernel" statement in isolinux.cfg. - -For a floppy image, the size of the image should be exactly one of the -following: - - 1,228,800 bytes - For a 1200K floppy image - 1,474,560 bytes - For a 1440K floppy image - 2,949,120 bytes - For a 2880K floppy image - -Any other size is assumed to be a hard disk image. In order to work -on as many systems as possible, a hard disk image should have exactly -one partition, marked active, that covers the entire size of the disk -image file. Even so, hard disk images are not supported on all -BIOSes. |
