In DOS configuration files, which file typically contains the BUFFERS= statement used to set disk buffer counts?

Introduction / Context:
DOS boots using two key configuration files: CONFIG.SYS and AUTOEXEC.BAT. Understanding which settings belong in which file is vital for legacy system setup, driver loading, and performance tuning (e.g., disk buffers and device drivers).

Given Data / Assumptions:

• BUFFERS= sets the number of disk buffers that DOS maintains.
• CONFIG.SYS is parsed by the DOS kernel during boot before AUTOEXEC.BAT.
• Other filenames in options are either unrelated or from other systems.

Concept / Approach:

System-level settings and device drivers (HIMEM.SYS, EMM386.EXE, BUFFERS=, FILES=) reside in CONFIG.SYS. AUTOEXEC.BAT typically sets environment variables and launches TSRs/utilities. Therefore, BUFFERS= belongs in CONFIG.SYS.

Step-by-Step Solution:

Verification / Alternative check:

DOS manuals list BUFFERS= under CONFIG.SYS directives alongside FILES= and LASTDRIVE=.

Why Other Options Are Wrong:

• Autoexec.bat: used for commands after kernel initialization, not kernel directives.
• Other filenames are not DOS boot files.

Common Pitfalls:

• Confusing device driver (.SYS) loading (CONFIG.SYS) with TSR launching (AUTOEXEC.BAT).

Final Answer:

Config.sys.
