What's New for the Windows 98 Startup Disk? The Startup Disk has changed significantly for Windows 98. The following items are new: - MULTI-CONFIG START MENU - REAL-MODE CD-ROM DRIVERS - EBD.CAB FILE - RAMDRIVE - WINDOWS 98 STARTUP PROBLEMS - USING THE TOOLS AVAILABLE ON THE STARTUP DISK Multi-Config Start Menu ========================== If you boot your computer using the new Windows 98 Startup Disk, a boot menu appears allowing you the option to load drivers for the most common CD-ROM drives or perform a normal clean boot. After you make your selection, the Config.sys file loads the appropriate CD-ROM driver (if selected) and then loads a 2MB RAMDrive. The RAMDrive is used to store all the diagnostic tools necessary to troubleshoot the most common problems. *Note* The RAMdrive may cause your CD-Rom to pushed back 1 drive letter. If your CD-Rom is usually drive D:, it will now be Drive E:. Real-Mode CD-ROM support ================================= The Windows 98 Startup Disk includes generic ATAPI IDE & SCSI CD-ROM drivers that allow your CD-ROM to function at MS-DOS when the Windows 98 GUI is not available. *Note*, not all CD-ROM drives are supported. If your CD-ROM drive does not function with these drivers, you must use the drivers that came with your CD-ROM drive. EBD.CAB file ================================= The Ebd.cab file is a compressed file whose contents are extracted to the Ramdrive during the startup process. The table below identifies the files in the Ebd.cab file. File Function Attrib.exe Add or remove file attributes Chkdsk.exe A simpler and smaller disk status tool Debug.exe Debugging utility Edit.com Real-mode emergency text editor Ext.exe New, simple file extract utility Format.com Disk format tool Mscdex.exe Microsoft CD-ROM file extension for MS-DOS Scandisk.exe Disk status tool Scandisk.ini Disk status tool configuration file Sys.com Transfers system files and make disk bootable Creating a RAMDrive ================================= The RAMDrive is created during the processing of the Config.sys file and is 2MB in size. The Ramdrive is created using system RAM to emulate a physical Hard Disk. Without creating the RAMdrive, we would not have enough space on a single 1.44 meg floppy disk to contain all the diagnostic tools as well as the CD-Rom drivers. Warning Since the RAMDrive is created during the processing of the Config.sys file and uses System RAM, it is only temporary. It will disappear if you restart your computer normally. List of all components on the EBD ==================================== The following table describes the function of each file copied to the EBD. File Function Aspi2dos.sys Real-Mode Adaptec CD-ROM driver Aspi4dos.sys Real-Mode Adaptec CD-ROM driver Aspi8dos.sys Real-Mode Adaptec CD-ROM driver Aspi8u2.sys Real-Mode Adaptec CD-ROM driver Aspicd.sys Real-Mode Adaptec CD-ROM driver Autoexec.bat Startup batch file Btcdrom.sys Mylex/BusLogic CD-ROM driver Btdosm.sys Mylex/BusLogic CD-ROM driver Command.com Command interpreter Config.sys Loads the device drivers Drvspace.bin Microsoft DriveSpace compression driver Ebd.cab Cab file containing extract utilities Ebd.sys File identifying the ESD Extract.exe File to expand the Ebd.cab file Fdisk.exe Disk partition tool Findramd.exe Utility to find the RAMDrive during startup Flashpt.sys Mylex/BusLogic CD-ROM driver Himem.sys XMS Memory Manager Io.sys System boot file Msdos.sys Boot option information (paths, multiboot, and so on) Oakcdrom.sys Generic device driver for ATAPI CD-ROM drives Ramdrive.sys Creates a Ramdrive during startup Setramd.bat Searches for first available drive to be a Ramdrive WINDOWS 98 STARTUP PROBLEMS ============================ This section includes some common troubleshooting steps that can be used when it's necessary to use the Windows 98 Startup Disk. These steps are designed to get the user at least into Safe-Mode where you have access to Windows 98 Help to further troubleshoot any issues. Starting Your Computer in Safe Mode ----------------------------------- There are several reasons why Windows 98 may fail to start properly. The first step in troubleshooting is to try starting your computer in Safe Mode. If Safe Mode works, you can then use the extensive Help system and troubleshooters located in the Start menu/Help option. >>>To start your computer in Safe Mode: 1. Remove the Startup Disk and restart your computer. After the computer restarts but before Windows begins to load, hold down the CTRL key until the Microsoft Windows 98 Startup Menu appears. (If you are running Windows 95, press the F8 key at the "Starting Windows 95" prompt.) 2. From the Startup menu, select Safe Mode. If you can start your computer in Safe Mode, use Windows 98 Help to resolve your original issue. Setup Fails and the Computer Will Not Start ------------------------------------------- There are a few common reasons why Windows 98 Setup may fail to complete successfully. The following section explains what you can do to recover from these situations. For more information on other Setup problems, see the Setup.txt file in the Win98 folder of your Windows 98 CD or Setup Disk #1. If you encounter any of these error messages while running Setup: * Invalid System Disk * Incorrect MS-DOS Version * Missing or Corrupted Command.com * Compression Driver errors It is likely that your computer's startup drive may need updated system files. You can use the SYS command to copy the needed files to your computer. NOTE: If you are currently loading compression software, you will need to know your host drive letter. This is typically H. If you are not loading any compression software, then you will need to SYS your C drive. >>>To use the SYS command to copy system files to your computer: 1. Restart your computer using the Windows 98 Startup Disk, select option 2 on the Startup menu, and then press ENTER. 2. At the A:\ prompt, type: SYS X: (where X is your Host or Startup drive). 3. If the procedure is successful, a "System transferred" message appears. If it is not successful, check to be sure you are typing the correct drive letter for your Host Drive. IMPORTANT: If you have installed software that came with your hard drive, be sure to read the documentation that describes how to start your computer using a floppy disk. Antivirus Software ------------------- If antivirus programs are left running during Setup, they may prevent Setup from properly updating the system files. If this occurs, disable or uninstall the antivirus program, and then run Setup again. NOTE: Some computers have built-in antivirus software. This built-in software should also be disabled before running Setup. If the software is left enabled, you may receive a warning message informing you that the Master Boot Record has changed. If you see such a message, you MUST accept these changes or Setup may stop responding. Setup Stops Responding During Hardware Detection ------------------------------------------------ If Setup stops responding while it is detecting the hardware in your computer, turn your computer off and wait a few seconds, then turn it back on. You may need to do this several times, because Setup could stop responding during several different detection modules. NOTE: Use the power switch to turn your computer completely off. Do not use the reset button or press CTRL+ALT+DELETE to restart your computer. If Setup still fails to complete successfully, it may be necessary to start your computer in Safe Mode so that you can view the Help topics associated with hardware detection. Compressed
