What is one way to increase available conventional memory in a DOS system?

• A. Add more RAM
• B. Install a new motherboard
• C. Add DOS=HIGH to the CONFIG.SYS file
• D. Upgrade to a new operating system

Answer: (C)

Adding the line DOS=HIGH to the CONFIG.SYS file is a method specifically designed to optimize how conventional memory is managed within a DOS system. By including this line, DOS is instructed to load itself into the high memory area (HMA), allowing more of the conventional memory (the first 640 KB of RAM) to be freed up for use by applications. This approach leverages the available memory more efficiently, especially since many DOS applications operate best when they have more conventional memory available. The other options, while related to computer upgrades or enhancements, do not specifically address the management and optimization of conventional memory within the context of a DOS system. Adding RAM or installing a new motherboard may improve overall system performance, but they do not specifically target the issue of conventional memory management. Similarly, upgrading to a new operating system may provide newer features and improvements that can enhance performance, but it wouldn't necessarily solve issues related to available conventional memory in an existing DOS setup.
