Use the FAT file system,Use DOS commands for file management and. other tasks,Describe the DOS bootup process and create. startup disks,Troubleshoot common DOS problems 2 3. Finding DOS and Understanding,its Strengths and Weaknesses. Versions of DOS,CP M was an important predecessor to DOS.
Many versions of DOS several introduced,by Microsoft MS. MS created PC DOS for IBM,Later licensed DOS as MS DOS to other. manufacturers,MS DOS 5 0 first version available as a separate. Finding DOS and Understanding,its Strengths and Weaknesses. Versions of DOS continued,PC DOS now works on Microsoft Intel.
compatible computers,Digital Research of CP M fame introduced. DR DOS in 1987,DR DOS 8 0 introduced in 2004 by DeviceLogics. FreeDOS distributed without charge under,GNU GPL license. Finding DOS and Understanding,its Strengths and Weaknesses. DOS Strengths,DOS for backward compatibility with DOS apps.
DOS when you need a small OS,DOS is more compact than Windows and hence. useful for embedded systems or for portability,DOS is popular as an operating system due to its. ability to pack all startup files on a single floppy. Finding DOS and Understanding,its Strengths and Weaknesses. DOS Strengths continued,The floppy disk is also known as the startup disk. Startup disk accommodates additional files such,as drivers and utilities.
Startup disk can be used for booting up a,computer and running special diagnostic programs. Finding DOS and Understanding,its Strengths and Weaknesses. DOS Weaknesses,Processor mode limits,Memory limits. Multitasking limits,Hard drive limits,Finding DOS and Understanding. its Strengths and Weaknesses,DOS Weaknesses continued.
Processor Mode Limits,Only supports real mode of operation of Intel. processors,Newer Intel processors start in the real mode and. newer OSs Windows Linux UNIX switch the, processor from the real mode to the protected mode. Memory Limits,Intel processors in real mode use only 1 MB. 640 KB of RAM conventional memory is workspace,for the OS applications and data.
384 KB of addresses reserved for system BIOS and,RAM and ROM on adapters 2 9. Finding DOS and Understanding,its Strengths and Weaknesses. DOS Weaknesses continued,Multitasking Limits,DOS is a single tasking OS. Hard Drive Limits,DOS only supports hard drives up to 7 8 GB. DOS uses logical drives that are 2 GB or less and,within the 7 8 GB total disk space limit.
A logical drive is a portion of the physical hard,drive with a letter assigned to it. Installing DOS,DOS Hardware Requirements,The general DOS hardware requirements for. MS DOS 6 22 and IBM PC DOS,An IBM or compatible personal computer. 6MB of free hard disk space for the DOS utilities,512KB of memory. Installing DOS,Preparing for DOS Installation,Assure that the computer is a complete system.
with all the necessary components,Setup program partitions and formats the. Partition an area of a physical hard disk that,contains one or more logical drives. Installing DOS,Partitioning a Hard Disk in MS DOS,Physical format is done at the factory. Master Boot Record MBR the 1st sector,on disk contains the partition table. Partitioning is the first step to prepare a,Each partition needs a logical format within.
each logical drive,Partitioning and formatting included in OS. installation,Installing DOS,Partitioning a Hard Disk in MS DOS continued. FDISK the partitioning program of MS DOS,Primary partition has only one logical drive. 2GB is maximum primary partition size in,Extended partition contains one or more. logical drives,After partitioning then format logical drives.
