. How to edit the files The auotexec.bat and the config.sys are edited by the MS-DOS command file. To edit these files, type edit c: autoexec.bat to edit the autoexec.bat file, or edit c: config.sys to edit the config.sys file.

1. Himem.sys Download

I have dos based system. When i run the kundali software it give me the error of himem.sys is missing. HIMEM.SYS is a DOS device driver which allows DOS programs to store data in extended memory via the Extended Memory Specification (XMS). This device driver is of particular importance because various versions of Microsoft Windows that ran on top of the DOS operating system required HIMEM.SYS to be loaded to be able to run.

If the mouse drivers are not loaded properly, the mouse will not work. If you have, or later versions of Windows it is recommended that you use the command; to run this program, click Start, Run, and type sysedit. Note: Windows XP and later no longer use the autoexec.bat or config.sys file. Remarking information Remarking lines within the autoexec.bat or the config.sys allows you to temporarily or permanently prevent a line from loading each time you boot the computer. To a line place 'REM ' in front of each line you want to skip. If you are encountering issues with a line in the autoexec.bat it is highly recommended that you remark the line instead of removing the line in case it needs to be placed back into the autoexec.bat. Getting additional memory The below commands help your computer load programs into memory more efficiently allowing you to have more memory for MS-DOS programs and.

Make sure you have the below three lines at the beginning of your config.sys file. DEVICE=C: Windows HIMEM.SYS DOS=HIGH,UMB DEVICE=C: Windows EMM386.EXE NOEMS By placing the DOS=HIGH,UMB on the second line, this can, in some cases, save memory because it is loading DOS into upper memory before loading the memory manager. Additionally, the first and third lines cannot be loaded into high memory because these lines are the memory managers. Load all your devices' in your config.sys and autoexec.bat into high memory.

Autoexec.bat layout Below is an example of how the autoexec.bat may look. @echo off SET SOUND=C: PROGRA1 CREATIVE CTSND SET BLASTER=A220 I5 D1 H5 P330 E620 T6 SET PATH=C: Windows;C: LH C: Windows COMMAND MSCDEX.EXE /D:123 Command Explanation @echo off Tells DOS to read the lines but not them back to the screen.

SET SOUND=C: PROGRA1 CREATIVE CTSND The set sound is telling the computer to send all events that the computer may run to that directory. SET BLASTER=A220 I5 D1 H5 P330 E620 T6 Tells the computer to set the Sound Blaster settings, which is a good line for computer games or other programs needing sound.

If you have this line in your autoexec.bat, you have all settings for your sound card. A220 = port address '220', I5 = IRQ 5, D1 = DMA 1 usually being the settings for most sound cards. SET PATH=C: Windows;C: Sets the computer to look in the C: Windows directory or the root if a command used at the prompt is not found. LH C: Windows COMMAND MSCDEX.EXE /D:123 Line used for the. If you have Windows 95+, the MSCDEX will always be in the C: Windows COMMAND. In Windows 3.x or DOS, this file is in either in C: DOS or C: Windows directory. The /D:123 is the name of the driver name that loads in upper memory; this can be anything, usually /D:MSCD0001.

Keep in mind that this is not the driver, it is the name for the driver. If you change this line it needs to also be changed in the config.sys on your CD-ROM line. If the two are not the same, your CD-ROM drive will not load. LH C: MOUSE MOUSE.EXE Loads the driver into memory.

However, not all mice use the same drivers. Although the mouse may use mouse.exe it could also be 'mouse.com' or 'mouse.sys', which is loaded in the config.sys. C: DOS SMARTDRV.EXE /X Loads the smartdrive disk cache utility into memory. See the page for additional information about this utility. DOSKEY DOS command to load into memory so when in DOS you can use it without having to load it. CLS MS-DOS command to clear screen.

Himem.sys Download

WIN Used for users using Windows 3.x, this line will load Windows automatically when booting the computer. Config.sys layout Below is an example of how the config.sys may look. DEVICE=C: Windows HIMEM.SYS DOS=HIGH,UMB DEVICE=C: Windows EMM386.EXE NOEMS FILES=30 STACKS=0,0 BUFFERS=20 DEVICEHIGH=C: Windows COMMAND ANSI.SYS DEVICEHIGH=C: MTMCDAI.SYS /D:123 Command Explanation DEVICE=C: Windows HIMEM.SYS The Himem.sys line is an important line; this line allows you to load drivers into high memory.

If this line is not present, Windows 3.x will not load. DOS=HIGH,UMB Load DOS into in an upper memory block. Note the location usually best placed after the HIMEM.SYS. DEVICE=C: Windows EMM386.EXE NOEMS The line loads the extended memory manager.

However, some older MS-DOS games have problems with extended memory and will not run without the NOEMS statement. FILES=30 The files line allow Windows to load 30 files at the same time.

However, going higher may decrease the computer's performance; 30 is found to work the best. Also, make sure that this line is all as one line and that there is not a space between and after the =. STACKS=0,0 The stacks line was first used in MS-DOS 3.2 and was used to swap the stack whenever an asynchronous hardware interrupt occurred.

Later in MS-DOS 3.3 the line STACKS=0,0 was added into the config.sys. In special circumstances, this line was changed to STACKS=9,128. The STACKS statement has a range of 8-64, 32-512. If a higher value is entered, you will receive a FATAL: Internal stack failure, system halted error message. BUFFERS=20 Buffers line is to load buffers into memory allowing Windows to load memory. DEVICEHIGH=C: Windows COMMAND ANSI.SYS The ansi.sys line is a driver for DOS to allow you to have different colors and sizes and special characters at the DOS prompt.

DEVICEHIGH=C: MTMCDAI.SYS /D:123 The for the CD-ROM drive. The /D:123 represents the name of the driver, which in this case is named 123, however, can be named anything, usually MSCD0001. However, keep in mind that the /D:123 must be exactly the same in config.sys and autoexec.bat.

If they are different, the CD-ROM will not work in MS-DOS. LASTDRIVE= Allows you to specify the last drive installed on the computer. It is not recommended this line be used unless you are using Windows 3.11 or earlier since later version of Windows will ignore this line. FCBS= Line used to specify the number of file control blocks for file sharing.

Should only be used when programs require it, and today, is not used or required. FCBS can utilize between 1 and 255. Technical support.
