How would you allow device drivers and TSR’s to be loaded into Upper Memory Blocks ? A. DOS=High B. devicehigh= C. loadhigh= D. DOS=UMB E. None of the above

DOS=High
devicehigh=
loadhigh=
DOS=UMB E. None of the above

The correct answer is B. devicehigh=.

The devicehigh command is used to load device drivers into upper memory blocks (UMBs). UMBs are unused areas of memory above 640 kilobytes (KB) that can be used to load device drivers and TSRs (terminate-and-stay-resident programs).

To use the devicehigh command, you must first create an UMB. You can do this by using the mem command to see how much unused memory you have above 640 KB. If you have at least 64 KB of unused memory, you can create an UMB by typing the following command:

memmaker /c

This will create a 64 KB UMB. You can then use the devicehigh command to load device drivers into the UMB. For example, to load the ANSI.SYS driver into the UMB, you would type the following command:

devicehigh=ansi.sys

You can also use the devicehigh command to load multiple device drivers into the same UMB. For example, to load the ANSI.SYS and GRAPHICS.SYS drivers into the same UMB, you would type the following command:

devicehigh=ansi.sys,graphics.sys

The devicehigh command is a powerful tool that can be used to free up conventional memory. By loading device drivers into UMBs, you can free up conventional memory for other programs. This can improve the performance of your computer.

The other options are not correct.

  • A. DOS=High is used to load DOS into upper memory.
  • C. loadhigh= is used to load TSRs into upper memory.
  • D. DOS=UMB is not a valid command.
  • E. None of the above is not a valid answer.
