Disk space for the installation of WINDOWS 98 WINDOWS 98 Setup requires a minimum of space on the hard disk, from 155 MB to 350 MB. Before you run WINDOWS 98 Setup, you need more or less of space on the hard disk to save your system files and applications provided with the operating system (depending on the number of selected components), in addition, require enough room to unpack the files from the CDROM during installation, and finally required possibly in addition to the space to keep the old operating system...

  • 110 or 240 Mega bytes for a minimal installation or complete.
  • 45 Mega bytes which are used temporarily to unpack files of the installation CDROM which are compressed and occupy only 80 Mega bytes.
  • 65 Mega bytes for the restoration of the old system files.
  • Space sufficient for applications that will be installed later and to preserve documents.
  • A total of 155 Mega bytes for a minimal installation, without possibility to restore the old system, or install other applications; or a total of at least 350 Mega bytes for maximum installation, but it will still provide additional space to install other applications

Installation types WINDOWS 98 Setup can be an update, first installation or a multi boot... There are several types of WINDOWS 98 Setup, depending on whether there is an operating system prior to installing and whether there is one or more of the operating system after the installation:

  • Update that takes parameters and keeps the programs installed on a previous version of WINDOWS (3.x or 95). The installation is performed from the operating system that is already present on the computer or from the DOS version of the old operating system (it must then prepare a startup disk or BOOT disk, optionally change the BOOT sequence of the BIOS with the drive A:\ in first place, and finally reboot or restart the computer with it in the floppy drive and once on the prompt launch the installation process...)
  • The first installation, when there is no operating system and the hard drive is blank. Installation is done so through the back, a small operating system which fits on a floppy disk (the BOOT disk or boot disk that comes with the installation of WINDOWS 98 CDROM) that allows to recognize the CD-ROM drive (to install the correct driver or a generic driver) and run the installation procedure.
  • A reinstall of WINDOWS 98 on a WINDOWS 98 system already installed.
  • A multi installation or the installation of several operating system.

The update Installationfrom a previous version of WINDOWSis a update. Upgrading from WINDOWS 3.x or WINDOWS 95 presents no difficulty, since the AUTORUN file.INF must run the Setup program as soon as the installation of WINDOWS 98 CDROM is inserted in the drive. This requires that the CDROM drive Autorun function does not disable in the registry with the entry "NoDriveTypeAutoRun" key:


Installing multi boot Multi boot tomultiple operating systems coexist, either because there is already an operating system (either a system DOS, WINDOWS 3.x, or another brand like OS/2, UNIX, LINUX,...) and you want to keep it parallel with WINDOWS 98, either by first installing WINDOWS 98 and another operating system. Multibooting is possible with older versions of the DOS or WINDOWS 3.x, but is not possible with WINDOWS 95 because WINDOWS 98 Setup replaces WINDOWS 95 (less than change the installation directory). The multiboot between WINDOWS 98 and LINUX is possible, it must install WINDOWS 98 first and then install LINUX, and is the 'loader LILO"(LInux LOader) which will do. The multiboot between WINDOWS 98 and WINDOWS NT is possible, and it is a "NT loader" which will boot. The installation of the WINDOWS 98 system files then occurs in a different "system partition", which can be formatted with one two (FAT16 or FAT32) file systems compatible with the WINDOWS 98 operating system. When multiple operating systems coexist, the "primary partition" must be formatted in FAT 16 to accept the MULTIBOOT (FAT 16 or VFAT is the only file system that is compatible with all IBM PC market compatible operating systems). The "primary partition" must be formatted in FAT 16 to make the option "Boot into MSDOS mode" part of the boot menu options. "Primary partition" of the first hard disk is also called "active partition", "boot partition" or "boot partition" because it is parsed by the BIOS (it is possible to change the partition say 'active' with FDISK or PQMAGIC), after the test procedure performed each time the computer starts(the program POST the BIOS, Power On Self Test, checks good hardware configuration of the computer, including the RAM). Where a single operating system is installed on the computer, BIOS searches on the "primary partition" information of the MBR (Master Boot Record or master record table of the hard disk). The MBR lists the logical partitions of a hard disk organization(primary partition, eventually the extended partition and its different lpars,...), the physical addresses of the partitions on the hard disk, and formatting of these type (ie the file of each system). Generally, the "primary partition" is also the "system partition", when this is not the unique partition of the hard disk. The MBR tells the BIOS the physical address on the hard disk of the "system partition", i.e. the location of the files (boot files). In other words, the BIOS research on the MBR location on the hard disk where the files of the operating system to be launched automatically. Read once the information of MBR, the BIOS starts loading the operating system (first the boot files and system files themselves). Generally, the boot files are on the primary partition which is also the active partition (we should call it the boot partition), while the actual system files may be located on another partition (that should be called the system partition). In the case of the MULTIBOOT, must be used a small program that is called a "charger". The "charger" can be registered in two places:

  • either on a boot disk with which you start the computer
  • either on the primary partition

The "charger" interrupts the start-up procedure and returns to the user, so that it selects the operating system they want to load into memory. The "charger" shows a small menu with the different available options, which correspond to the different operating systems that are installed on the computer. The user selects one of the operating systems, it validates its choices and the "charger" is responsible for load in memory the files corresponding systems, it can be found on the "system partition" correspondent. So to summarize :

  1. The user turn on his computer.
  2. The BIOS of the motherboard is launched and performs a number of tests (POST).
  3. The BIOS looks in the MBR looking for the active partition (and boot files), but it a multi boot loader it loads into RAM.
  4. Multi boot loader is then started and the startup procedure is stopped
  5. The user selected the operating system
  6. The charger looks and launches the system files corresponding to the operating system that has been chosen by the user (at first boot files that should be placed in the active partition, and then file systems that can be placed in another partition, the system partition).

The minimum configuration of WINDOWS 98 The minimum configuration is the smallest hardware configuration that works.

  • 486DX 66 Mhz processor
  • 256-Color VGA graphics card
  • Floppy drive 31/2 inches
  • 16 MB of memory (RAM)
  • 125 MB to 360 MB of space on the hard drive (ROM)
  • Two-button WINDOWS compatible mouse

But in General, for comfortable use, it is best to move towards " recommended configuration " (IE a Pentium, 32 MB of RAM, and a good hard disk).

The installation from DOS The installation of WINDOWS 98 from the DOS prompt implies that the computer has already started and it works with the MS-DOS operating system. It took for this start the computer with a BOOT disk, which must contain the driver CDROM of the constructor (or the generic drivers that offers MICROSOFT) to gain access to the CDROM drive and to use the WINDOWS 98 installation CDROM... When the computer runs under MS-DOS, a black screen shows the prompt, i.e. a command prompt:


From this prompt, should be placed on the drive's CDROM (X:\), by typing the following command line:


The prompt changes, and presents the CDROM drive (if it has been recognized through the CDROM driver):


Just, then run the Setup program that is located at the root of the CDROM drive:


Preparations before the update

  • Uninstall old programs that no longer, serve and clean up folders and files obsolete and redundant...
  • Check the disk with an anti-virus update...
  • Check the disk with SCANDISK
  • Defragment the disk
  • Disable the screen saver
  • Close the TSR programs
  • Create a backup
  • Create a BOOT disk

WINDOWS 98 restoration can be performed with shareware

  • GOBACK 2.2 that accounts for the boot sector of the hard disk and prevents the multiboot

Installing standardized Windows 95 & 98

Standardized Windows 95 & 98 installation can be performed in two ways:

  • Via a script and through the network. A distribution server shares files to install Windows 95 & 98:
  • Using a NETSETUP program.EXE
  • By copying the files from the network
  • Via an image, a clone. If all PCs are equipped with the same materials, then they can have the same configuration.
  • Ghost of Innovation Software
  • Drive Image of Power Quest
  • The procedure is done in four steps:
  1. Fully configure a PC.
  2. Copy the image of its hard drive (a full on support and consistent copy) or a dispensing apparatus (a removable cartridge, a CDROM, or the network hard drive).
  3. Copy the image on the hard disks of the cloned positions.
  4. Do some editing as change the name of each machine or IP address that must be unique on each station.

The CDROM to install Windows 95 (version 4.00.950 a) contains the NETSETUP program.EXEwhich allows a Windows 95 installation through a network server. The NETSETUP program is found in the following directory:


From Windows 95 OSR2, the program NETSETUP.EXE is no longer available... To perform an installation over the network:

  1. SE logger on the network server as administrator.
  2. Copy the installation files (the WIN98 folder that contains compressed files) from Windows 95 & 98 in a shared read-only directory.
  3. SE logger on each computer networks in MS-DOS mode with network support and run the installation procedure

Windows 98 procedures

  • To install Windows 98 with an MSBATCH installation script.INF (with BATCH.)(EXE)

Creating a file MSBATCH.INF can automate an installation of Windows 98, and choose the Setup:

The time zone The name of the user The name of the computer The network settings The videos settings The security settings Etc...
The BATCH program.EXE to create a file MSBATCH.INF with inside all parameters predefined needed the Windows 98 Setup program. Fields that are left empty in BATCH.EXE will be requested during the process of installing Windows 98 since it have not been populated in the MSBATCH.INF file. If all the parameters are populated in the installation script (MSBATCH.)(INF) so Windows 98 Setup can take place without any intervention.
Launch the BATCH program.EXE located in the installation CDROM in Windows 98, or install 'Batch Setup' on the computer with the SETUP Installer.EXE:
The 'click here to retrieve settings from the registry' button allows you to copy in the script (MSBATCH.)(INF) the parameters of the station which launched BATCH.EXE. The other buttons to specify some options:
The network settings The optional components of Windows 98 Advanced options as a rule (POLEDIT) file The 'Done' button to save the MSBATCH.INF file. It is possible that the name of the file ".""INF" is different. To work, the installation script must have the name "MSBATCH."'INF '.
Copy the file «MSBATCH.»"INF" in the same directory as the installation files for Windows 98 (WIN98 in the installation of Windows 98 CDROM). The installation of Windows 98 CDROM contains sample files MSBATCH.INF in the following directory:
  • To manually change a file MSBATCH.INF (with NOTEPAD.)(EXE)
Moved example to include in the installation script to MSBATCH.INF update of Service Pack 1 of Microsoft for the 1era version of Windows 95 (4.00.950 a). Open the file MSBATCH.INF in notepad Make the necessary changes... It is possible, based on groups users, to have several types of file MSBATCH.INF, several type of logon script and several types of application to install or update the network...
  • To perform installations or updates of Windows 98 via the network (with a logon script)
Create a user account with which to connect to the network users to perform them even the installation of Windows 98 or an update. Prohibit to change the password of this account. Copy the Setup from the Windows 98 CDROM files in a shared directory on the distribution server. Set the directory to read-only access rights. Write a logon script for the user account. The syntax of the logon script are different depending on the network operating system...
