Mtools is an open source collection of utilities to allow a Unix operating system to manipulate files on an MS-DOS file system, typically a floppy disk or floppy disk image. [2] [3] The mtools are part of the GNU Project and are released under the GNU General Public License (GPL-3.0-or-later).
It is used to make an already formatted medium bootable. It will install a boot sector capable of booting the operating system into the first logical sector of the volume. Further, it will copy the principal DOS system files, that is, the DOS-BIOS (IO.SYS or IBMBIO.COM) and the DOS kernel (MSDOS.SYS or IBMDOS.COM) into the root directory of the ...
[7] [8] On 386 PCs with a minimum of 4 MB of RAM, the floppy would boot a minimal DR-DOS 7.02 system complete with memory manager, RAM disk, dial-up modem, LAN, mouse and display drivers and automatically launch into the graphical browser, without ever touching the machine's hard disk. Users could start browsing the web immediately after ...
FED-UP is the Floppy Enhanced DivX Universal Player. [21] FUZOMA is a FreeDOS-based distribution that can boot from a floppy disk and converts older computers into educational tools for children. [22] XFDOS is a FreeDOS-based distribution with a graphical user interface, porting Nano-X and FLTK. [23] [24] [25] [26]
Ranish Partition Manager is a freeware hard disk partition editor, disk cloning utility, and boot manager, that gives a high level of control for creating multi-boot systems. [1] [2] It is available on the freeware live CD SystemRescueCD and the Ultimate Boot CD (not the Windows version). It runs under MS-DOS, PC DOS, DR-DOS, or FreeDOS.
Likewise, the IO.SYS of the older system is named IO.DOS for as long as Windows 9x is active. DR-DOS 7.06 (only this version) also follows this scheme and the IO.SYS filename in order to become bootable via MS-DOS boot sectors. Similarly, FreeDOS uses a combined system file as well, but names it KERNEL.SYS.
Once MSX-DOS has been loaded, the system searches the MSX-DOS disk for the COMMAND.COM file and loads it into memory. [2] In that case, the BDOS bypassed the BASIC ROMs, so that the whole 64 KB of address space of the Z80 microprocessor inside the MSX computer could be used for the DOS or for other boot-able disks, for example disk based games.
BIOS interrupt calls perform hardware control or I/O functions requested by a program, return system information to the program, or do both. A key element of the purpose of BIOS calls is abstraction - the BIOS calls perform generally defined functions, and the specific details of how those functions are executed on the particular hardware of the system are encapsulated in the BIOS and hidden ...
