CONFIG. SYS is an important file in a DOS system, and its configuration directly affects the use and efficiency of the system. If improperly configured, many programs may not work correctly. Therefore, it is very necessary and important to correctly and rationally configure Config.sys files. Let me tell you about the commands in Config.sys and how to configure them.
CONFIG. The commands in SYS:
Note: All commands with high end (such as devicehigh) are transferred to the UMB (upper memory), but some such commands (such as Fileshigh) must be used in MS-DOS 7.x versions.
Accdate: Specifies whether the date on which the file is last accessed is logged for each drive.
Usage: accdate= drive 1+|-[drive 2+|-] ...
For example: accdate=c+ d+ e+ will record the date the file was last accessed in the C,d,e disk.
This command is only available in MS-DOS 7.x.
Break: Sets or clears the extended CTRL + C check.
Usage: break=on| Off
Buffers/buffershigh: Allocates memory for a specified number of disk buffers.
Usage: buffers= number of disk buffers, [number of buffers in dependent cache]
Device/devicehigh: Loads the specified device driver into memory.
Usage: device/devicehigh filename [parameters]
Where the filename is the full path to the file, such as C:\DOS\HIMEM. SYS.
DOS: For DOS system configuration, such as whether to use HMA (high memory area).
Usage: dos=[high| Low][,umb|,noumb][,auto|,noauto][,single]
Among them, high and low indicate that using HMA or not using Hma,umb and NOUMB indicates that the system is automatically configured or not configured with either Umb,auto or Noauto, and single represents the use of one-mode dos. where Auto/noauto and single are only used in MS-DOS 7.x.
Drivparm: Sets parameters for an existing physical device.
Note: This command is used very little, I have no use, so temporarily skipped.
Fcbs/fcbshigh: Specifies the number of file control blocks (FCB) that can be opened at the same time.
Usage: The number of FCB that fcbs/fcbshigh= can open at the same time.
Note: Because the FCB is mainly used in DOS 1.x, for the high version, so the system can be automatically configured.
Files/fileshigh: Specifies the number of files that can be accessed concurrently.
Usage: The number of files that files/fileshigh= can access at the same time.
Note: The general Files/fileshigh of the set value of around 30 more appropriate.
Install/installhigh: Used to load TSR (memory resident program).
Usage: install/installhigh= filename [parameters]
such as: Installhigh=c:\dos\doskey.com/appedit
