  1. Using OS/2 Warp Version 4 OS/2 Background and Concepts

  2. What is OS/2? • A successor to DOS • Powerful, flexible and easy to use • Multitasking • Fully utilizes the power of the CPU • Uses all available memory, including virtual memory

  3. Advantages of OS/2 Compared to DOS • OS/2 will use all available memory • DOS only uses 640 KB • OS/2 uses virtual memory • DOS cannot • OS/2 fully utilizes the CPU • DOS uses only a fraction of the power available • Unlike DOS, OS/2 provides a powerful graphical user interface (GUI)

  4. Multitasking • The ability to run more than one program simultaneously • Each program uses the CPU for a small fraction of a second, before the next program is given some CPU time Databases Word Processors Graphics Communications

  5. All in one box! OS/2 and Support for DOS and Windows • OS/2 runs: • OS/2 programs • MS Windows 3.1 programs • DOS programs • Warp 4 does not currently run MS Windows 95 programs

  6. OS/2 and Memory • The sensible minimum for running OS/2 Warp is 8 MB with 12 or 16 MB being recommended for serious use • Power users often use 32 or even 64 MB of memory OS/2

  7. OS/2 and Filing Systems • DOS only used the File Allocation Table (FAT) • OS/2 can use the FAT or High Performance File System (HPFS) • The file system is the link between the operating system and the physical files stored on the disk

  8. OS/2 BIG is beautiful Hardware Requirements • Minimum requirements are 8 MB of RAM and 386 CPU • Use 8 MB as a sensible minimum if you want the system to boot up by lunch time!

  9. Just follow the instructions! Installation • Simple, menu guided installation routine • Sometimes goes wrong if you have a non-standard mix of hardware
