The Microsoft Guide to Managing Memory with MS-DOS 6 [antikvár]

Introduction Memory management is a subject that has been avoided for way too long. Now the memory issue has exploded, and everyone is scrambling for cover. A few years ago there was only expanded memory. Then came extended memory. It was an $800 answer in Double Jeopardy: Which is which? Yet nagging questions still loomed: What can I do with that memory? What makes it useful? Since the introduction of MS-DOS 5, the first version of the operating system to address the issue of memory management, people who have long been avoiding the subject are staring it in the face. How can I use all that extra memory in my computer? And what can MS-DOS do with that memory? Now MS-DOS 6 offers even more memory-management abilities. Thanks to the handy MemMaker utility, setting up and configuring your PC's memory is a cinch. But there are still important issues, concepts, and buzzwords that will dog you to no end. Although MS-DOS doesn't perform memory management automatically, it does assume you know what you want; MS-DOS gives you options and lets you make choices based on your personal needs. Accordingly, no one-paragraph memory solution will work for everyone. But new commands exist that can be exploited. Consider this command: dos=high That one line in your CONFIG.SYS file can help free up some 50 KB of your main memory. MS-DOS has other tricks: ¦ The HIMEM.SYS device driver allows MS-DOS to access an extra 64-KB region of memory and opens the door to megabytes of extra memory.
