The final version of the MSCDEX program was 2.25, [citation needed] included with Windows 95 and used when creating bootable floppy disks with CD-ROM support. Starting with Windows 95, CD-ROM access became possible through a 32-bit CDFS driver. The driver uses the Microsoft networks interface in MS-DOS. This is the reason that at least version ...
Originally MS-DOS was designed to be an operating system that could run on any computer with a 8086-family microprocessor.It competed with other operating systems written for such computers, such as CP/M-86 and UCSD Pascal.
MS-DOS 7.0 was included in Windows 95's first retail release. It contains support for VFAT long file names when run in a Windows Virtual 8086 box or with an LFN driver such as DOSLFN. JO.SYS is an alternative filename of the IO.SYS kernel file and used as such for "special purposes". JO.SYS allows booting from either CD-ROM drive or hard disk.
FDISK has the ability to display information about, create, and delete DOS partitions or logical DOS drive. It can also install a standard master boot record on the hard drive. The command is available in MS-DOS versions 3.2 and later and IBM PC DOS 2.0 releases and later. [1]
Similar to INSTALL under DOS, loads programs in CONFIG.SYS. Similar to RUN under OS/2, but runs in foreground and halts CONFIG.SYS processing until return. CAPSLOCK (DR-DOS 7.02 and higher only) Specifies whether the keyboard ⇪ Caps Lock status is turned on or off. [8] CDDNAME (PTS-DOS only) Specifies the name of the CD-ROM hardware driver.
RealPC was provided with MS-DOS 6.22 already installed, so you could immediately run MS-DOS games and applications on your Macintosh. Linux was not supported and due to shared RAM between Mac OS and RealPC Windows 98 was the reasonable limit. RealPC was able to convert Virtual-PC hard disk files to use and run the installed OS.
Finally MS-DOS 7.1 (the DOS component of Windows 9x) added support for FAT32 which used 32-bit allocation entries and could support hard drives up to 137 GiB and beyond. Starting with DOS 3.1, file redirector support was added to DOS. This was initially used to support networking but was later used to support CD-ROM drives with MSCDEX. IBM PC ...
MS-DOS / PC DOS and some related disk operating systems use the files mentioned here. System Files: [1] IO.SYS (or IBMBIO.COM): This contains the system initialization code and builtin device drivers; MSDOS.SYS (or IBMDOS.COM): This contains the DOS kernel. Command-line interpreter (Shell): COMMAND.COM: This is the command interpreter.
