Boot CD need help

**SLiDer84** · September 3, 2007

Hi Friends,

I'm trying do make my own BOOT CD. But I have some problems with understanding the autoexec file. Is here anyone who could comment this autoexec file step by step what are doing all this lines??

@ECHO OFF

set EXPAND=YES

SET DIRCMD=/O:N

set LglDrv=27 * 26 Z 25 Y 24 X 23 W 22 V 21 U 20 T 19 S 18 R 17 Q 16 P 15

set LglDrv=%LglDrv% O 14 N 13 M 12 L 11 K 10 J 9 I 8 H 7 G 6 F 5 E 4 D 3 C

cls

IF "%config%"=="NETCD" echo Loading Network Configuration Utility v3.55

IF "%config%"=="NET" echo Loading Network Configuration Utility v3.55

IF "%config%"=="GIGNET" echo Loading Network Configuration Utility v3.55

call setramd.bat %LglDrv%

set temp=%RAMD%:\tmp

set tmp=%RAMD%:\tmp

path=%RAMD%:\;a:\;%CDROM%:\

This is a multi-configuration autoexec.bat.

You cannot say what it actually does unless you look at the accompanying CONFIG.SYS.

Moreover it calls a few other .bat and "not-standard" .exe files, each of which can do several other tasks:

setramd.bat

makeboot.exe

archive.exe

...

runlast.bat

It seems to be "hardcoded" for the A:\ drive.

Basically it appears to let the user choose between three possible configurations, "NETCD", "NET" and "GIGNET", then (most probably) through setramd.bat creates a RAMdisk where a number of programs and settings are copied and executed.

It is not at all difficult to follow it, but you need some basic primer on batch commands and autoexec.bat/config.sys to be able to customize it, some links:

Maybe could somebody help me to create te autoexec and config.sys files. I wont do have 3 possibilities:

one would be

Start with CD support

Start with CD and Net support

Start with only net support.

I have working boot disk but how you can see there are 5

possibilities:

menuitem=CD, Start computer with CD-ROM support.

menuitem=NET, Start computer with Network support.

menuitem=GIGNET, Mode ONLY for Intel Gigabit network support

menuitem=NETCD, Start the computer with CD-ROM and Network support.

menuitem=NONE, Start the computer with basic system.

and i need only 3

my config.sys looks like that:

[menu]

menuitem=CD, Start computer with CD-ROM support.

menuitem=NET, Start computer with Network support.

menuitem=GIGNET, Mode ONLY for Intel Gigabit network support

menuitem=NETCD, Start the computer with CD-ROM and Network support.

menuitem=NONE, Start the computer with basic system.

menudefault=NET,30

menucolor=7,0

[CD]

device=himem.sys /testmem:off

fileshigh=30

buffershigh=15

dos=high,umb

stacks=9,256

devicehigh=ramdrive.sys /E 4096

lastdrive=z

device=oakcdrom.sys /D:mscd001

[NET]

device=himem.sys

devicehigh=ramdrive.sys /E 4096

device=emm386.exe

DOS=HIGH,UMB,AUTO

SHELL=A:\COMMAND.COM /E:1024 /P

STACKSHIGH=0,0

FCBSHIGH=1,0

FILESHIGH=60

BUFFERSHIGH=15

lastdrive=Z

devicehigh=ifshlp.sys

[GIGNET]

device=himem.sys

devicehigh=ramdrive.sys /E 4096

DOS=HIGH,UMB,AUTO

SHELL=A:\COMMAND.COM /E:1024 /P

STACKSHIGH=0,0

FCBSHIGH=1,0

FILESHIGH=60

BUFFERSHIGH=15

lastdrive=Z

devicehigh=ifshlp.sys

[NETCD]

device=himem.sys

devicehigh=ramdrive.sys /E 4096

device=emm386.exe

DOS=HIGH,UMB,AUTO

STACKSHIGH=0,0

FCBSHIGH=1,0

FILESHIGH=60

BUFFERSHIGH=15

lastdrive=Z

devicehigh=ifshlp.sys

devicehigh=oakcdrom.sys /D:mscd001

[NONE]

files=60

stacks=0,0

buffers=30

lastdrive=Z

Well, that won't be difficult, just delete what you don't need!

Config.sys:

menuitem=NET, Start computer with Network support.
menuitem=GIGNET, Mode ONLY for Intel Gigabit network support
menuitem=NETCD, Start the computer with CD-ROM and Network support.
menuitem=NONE, Start the computer with basic system.
menudefault=NET,30
menucolor=7,0
[CD]
device=himem.sys /testmem:off
fileshigh=30
buffershigh=15
dos=high,umb
stacks=9,256
devicehigh=ramdrive.sys /E 4096
lastdrive=z
device=oakcdrom.sys /D:mscd001
[NET]
device=himem.sys
devicehigh=ramdrive.sys /E 4096

[NONE]
files=60
stacks=0,0
buffers=30
lastdrive=Z

Autoexec.bat (but you cam also leave it as is):

@ECHO OFF
set EXPAND=YES
SET DIRCMD=/O:N
set LglDrv=27 * 26 Z 25 Y 24 X 23 W 22 V 21 U 20 T 19 S 18 R 17 Q 16 P 15
set LglDrv=%LglDrv% O 14 N 13 M 12 L 11 K 10 J 9 I 8 H 7 G 6 F 5 E 4 D 3 C
cls
IF "%config%"=="NETCD" echo Loading Network Configuration Utility v3.55
IF "%config%"=="NET" echo Loading Network Configuration Utility v3.55
IF "%config%"=="GIGNET" echo Loading Network Configuration Utility v3.55
call setramd.bat %LglDrv%
set temp=%RAMD%:\tmp
set tmp=%RAMD%:\tmp
path=%RAMD%:\;a:\;%CDROM%:\
copy a:\command.com %RAMD%:\ >nul
set comspec=%RAMD%:\command.com
IF "%config%"=="NONE" GOTO QUIT
:EXT
%RAMD%:
MD NET
IF "%config%"=="CD" goto NONET
IF "%config%"=="NONE" goto NONET
A:\archive makeboot.exe %RAMD%:\NET >nul
A:\archive netcards.ini %RAMD%:\NET >nul
A:\archive tcputils.ini %RAMD%:\NET >nul
COPY A:\LMHOSTS %RAMD%:\NET > nul
%RAMD%:
CD NET
%RAMD%:\NET\makeboot.exe /n%RAMD%:\NET
:NONET
echo Copying System Files into memory...
COPY A:\ARCHIVE.EXE %RAMD%:\ >nul
echo.
echo Extracting...
%RAMD%:\archive -N %RAMD%:\NET >nul
%RAMD%:
IF "%config%"=="NET" GOTO NET
IF "%config%"=="GIGNET" GOTO NET
LH %ramd%:\NET\MSCDEX.EXE /D:mscd001 /L:%CDROM%
IF "%config%"=="NETCD" GOTO NET
echo.
GOTO QUIT
:NET
CLS
%RAMD%:
CD\NET
path=%path%;a:\;%RAMD%:;%RAMD%:\NET
if exist a:\netdrv\*.* copy a:\netdrv\*.* %RAMD%:\net
LH %RAMD%:\net\net initialize
%RAMD%:\net\netbind.com
%RAMD%:\net\umb.com
LH %RAMD%:\net\tcptsr.exe
LH %RAMD%:\net\tinyrfc.exe
LH %RAMD%:\net\nmtsr.exe
LH %RAMD%:\net\emsbfr.exe
if exist %RAMD%:\net\runlast.bat call %RAMD%:\net\runlast.bat
if not exist %RAMD%:\net\runlast.bat LH %RAMD%:\net\net logon /SAVEPW:NO /Y
goto QUIT
:QUIT
set CDROM=
set LglDrv=

However both files could be "better" written, avoiding some duplicates entries, using a [Common] part.

I would like to make it as simple as it could be if you could please help me with this I now that i'm getting with this files some errors i think that in those files are some errors.

And I have some questions

do i need this:

IF "%config%"=="NETCD" echo Loading Network Configuration Utility v3.55
IF "%config%"=="NET" echo Loading Network Configuration Utility v3.55

I think that this is only showing some text.

Why the section :EXT is not closed on the end with goto QUIT

And one more thing i don't now realy where to put the command IF "%config%"== I can see it in ext: nonet: can't it be before the section EXT: ?
