There are versions of Guest for Windows 95/98, Windows 3.1/DOS and Macintosh systems: * For Windows 95/98, run GUEST9X.EXE from the Windows/DOS Install disk (floppy or CD). If you encounter any problems, see "GUEST9x.HLP" on the Install diskette. * For Windows 3.1/DOS systems, run GUEST.EXE from the from the Windows/DOS Install diskette. Refer to the GUESTHLP.TXT file on the Install diskette for additional information on using GUEST.EXE with IBM- compatible PC's. * For information on using Guest on Macintosh systems, refer to the GUESTHLP.TXT file on the Windows/DOS Install diskette. NOTE: On Windows 3.1, DOS, or Macintosh systems, running the Guest program provides a temporary driver installation that is removed when the computer is shut down or restarted. Running Guest permanently installs the drivers needed to support Iomega hardware under Windows 95/98. _________________________________________________________ Section 2 Software Installation Troubleshooting Refer to the MANUAL.EXE file on the Windows/DOS Install diskette for software troubleshooting information on computers running Windows 95/98, Windows 3.1, and DOS. Section 4 in this Readme file contains detailed instructions on accessing MANUAL.EXE. Note for users of Adaptec EZ-SCSI: For information on using Iomega software and Adaptec EZ-SCSI on the same system, refer to "Special Information for Users of Adaptec EZ-SCSI" in Appendix A of MANUAL.EXE. _________________________________________________________ Section 3 Electronic Manuals The Iomega software package for Windows/DOS includes two electronic manuals: * The "Iomega Installation Manual" (MANUAL.EXE) which contains complete installation and problem-solving information for Iomega software under Windows 95/98, Windows 3.1, and DOS. * The "User's Reference Manual" (REFMAN.EXE) which contains reference information on Iomega SCSI software, including the Iomega Driver, configuration program, and Iomega SCSI Utilities. To access the Installation Manual, insert the Windows/DOS "Install" disk in an appropriate drive (floppy or CD-ROM), go to the DOS prompt, and type: A: (or D: where D is your CD-ROM drive) MANUAL You can also run the Installation Manual from the Windows File Manager by selecting drive A: and double-clicking on MANUAL.EXE. Under Windows 95/98, you can access the Installation Manual by double-clicking on the floppy drive in My Computer and then double-clicking on the "Manual" icon. The User's Reference Manual is located in the DOSSTUFF directory on the Zip "tools" disk and installed with the Iomega SCSI software package. Use the following procedure if you want to access the reference manual before installing your software: 1. Insert the "Install" disk (floppy or CD) for Windows/DOS into the appropriate computer drive and the "tools" disk into the Jaz drive. 2. Go to the DOS prompt and type: a:guest.exe (Install floppy in drive A) or b:guest.exe (Install floppy in drive B) 3. Note the drive letter Guest assigns to your Zip drive and use it in place of "d:" in the following command line: d:\dosstuff\refman If you install Iomega SCSI software using the INSTALL program, you can access the User's Reference manual from the C:\IOMEGA directory after the software installation is complete. Go to the DOS prompt and type: c: cd \iomega refman _________________________________________________________ Section 4 Cautions and Technical Notes ______________________________ Section 4.1 Microsoft Disk Copy Utilities CAUTION! Do NOT use DISKCOPY.EXE or the Windows 95/98 right mouse CopyDisk utility with your Zip drive. These utilities were designed for use with floppy drives and do not work correctly with other removable drives. Use an Iomega disk copying utility to copy disks (either Copy Machine or Iomega SCSI Disk Copy). ______________________________ Section 4.2 FDISK CAUTION! Do not use FDISK on any removable disk. FDISK is designed for partitioning fixed disks. Partitioning any type of removable media can lead to unexpected results. ______________________________ Section 4.3 32-bit Access If you are using Windows 3.11 or Windows for Workgroups and want to use Copy Machine, make sure that 32-bit disk and file access is turned off. (This option is available when changing virtual memory options under "386 Enhanced" in the Windows Control Panel.) NOTE: Windows 3.1 does not support 32-bit access for removable disks drives. If 32-bit access is not turned off, the hard drive will NOT appear in the Copy Machine window. ______________________________ Section 4.4 Windows Format Utility If you are using Windows 3.1, do not use the format utility available in Windows File Manager to format Zip disks. Use an Iomega format utility (either Iomega SCSI Format or Format in Iomega Tools). ______________________________ Section 4.5 Microsoft Backup Microsoft Backup does not support removable disk drives other than floppy drives. You can use Copy Machine to copy files on your hard disk to the Zip drive, or you can use the Windows File Manager to drag-and-drop files you want to back up to Zip disks. ______________________________ Section 4.6 Compression CAUTION! If you are using a compression utility on a removable disk (for example, a Zip disk), you should make that disk nonremovable (or lock the disk in the drive) whenever the compressed volume is mounted. Removing a disk while the compressed volume is mounted could result in lost data. To remove the disk, first unmount the compressed volume, then unlock the drive. Refer to the electronic "User's Reference Manual" (REFMAN.EXE) for detailed information on locking and unlocking drives. CAUTION! Do not use any disk compression software to compress removable boot disks. Iomega SCSI Utilities with Stacker 4.0 When using Stacker 4.0 and Iomega SCSI, mounted, stacked drives will not appear on the graphical user interface screen for the Iomega SCSI Utilities. In order to use an Iomega SCSI utility on a stacked drive, you must first unmount the drive. ______________________________ Section 4.7 Installing Applications to the Zip Drive Certain applications and games will install only to a fixed disk. To install these programs to the Zip drive, use the Iomega Tools "Make Nonremovable" or "Lock" utility to make the Zip drive appear as a hard drive to the system. After the software installation is complete, use "Make Removable" or "Unlock" to restore disk removability. _________________________________________________________ Section 5 Pass-Through on the Parallel Port Zip Drive This section describes how to handle problems you may encounter when connecting printers or other parallel port devices to the pass-through connector on the Zip drive. ______________________________ Section 5.1 Printers The parallel port Zip drive supports most printers on the pass-through connector; however, some printers require exclusive use of the parallel port and will not work correctly when connected to the Zip pass-through. Because these printers cannot share the parallel port, your system may stop responding if you attempt to use the printer and your Zip drive at the same time (for example, if you attempt to print a file from a Zip disk). If you are having problems with your printer when it is connected to the Zip pass-through connector, try the following: * Try powering on your computer, printer, and Zip drive all at the same time by plugging them into the same power strip and applying power at the power strip. * If you are using Windows 3.1, disable Disk Watch by removing it from your Windows Startup folder and then restarting Windows. Disk Watch periodically wakes up the Zip drive and checks its status, which temporarily disables the Zip pass-through. * Some Print Cache programs may conflict with the parallel port Zip drive. If you have Print Cache on your system, disable the audio warning messages for both Windows and DOS using the reinstall procedure in the Print Cache manual. (If you encounter problems reinstalling, please contact your Print Cache Software Technical Support.) * If you have Microsoft Print System installed on your computer, try using it to disable bi-directional communication to the printer. (Remove the check mark from the box next to "Use bi-directional communication.") * Try setting your printer to "Print to File" whenever it's not in use. This will enable you to use your Zip drive without problems as long as you are not printing. When you want to print a file from your hard disk (or any disk other than a Zip disk), close any files that may be open on your Zip disk and return the printer setting to normal. Do not attempt to access your Zip drive until the print job is completed and you have changed the printer setting back to "Print to File." If you are unable to use your printer and the Zip drive at the same time, the best solution is to add an additional parallel port to your computer, then use the Zip drive on one parallel port and your printer on the other. Most computer stores carry simple I/O cards that let you easily add a new parallel port. Warp Nine Engineering (formerly FarPoint Communications) produces an I/O card, F/PortPlus, which is fully compatible with the Zip drive and will improve your drive's performance. (Information on this card is available from Iomega's Automated FAX Help system at (801)778-5763, or you can contact Warp Nine Engineering at http://www.fapo.com.) Contact your computer dealer if you wish to purchase a card. ______________________________ Section 5.2 Other parallel port devices Parallel port devices other than printers may or may not work on the Zip pass-through connector. This problem exists because computer parallel ports were not originally designed for devices other than printers. If you try placing a device other than a printer on the Zip pass-through, or place the Zip drive on another device's pass-through, there are no guarantees that it will work correctly. In the future there will be a standard for daisy-chaining devices on the parallel port; when this standard is implemented, Iomega will also conform to it. In the mean time, try the suggestions listed under Section 7.1 for solving printer problems. If your parallel port devices still do not operate correctly on the Zip pass-through connector, or the Zip drive does not operate correctly on their pass-through, you may want to think about adding an extra parallel port to your computer as described in Section 7.1. _________________________________________________________ Section 6 Optimizing Parallel Port Zip Drive Transfer Speed under DOS The parallel port model of the Zip drive supports three modes of data transfer which have different transfer speeds. To ensure the broadest base of compatibility for the Zip drive, the Iomega installation software for DOS automatically uses the most compatible, but slowest, transfer mode. In this mode, the transfer speed for the Zip drive is about 2MB to 6MB per minute, depending on the computer's processor speed. If the computer has a bi-directional parallel port, the Zip drive can be set to use a mode which provides data transfer speeds of 6MB to 17MB per minute, depending on the computer's processor speed. (If you are not sure whether your computer has a bi-directional parallel port, refer to the owner's manual that came with your computer.) The fastest mode supported by the Zip drive requires a special "Enhanced Parallel Port" (EPP) chip set to be present on the host computer. In this mode, the data transfer speed for the Zip drive is about 17MB to 22MB per minute, depending on the computer's processor speed. Because of the variety of EPP chip sets, and because there are some chip sets that mimic a true EPP chip but do not support EPP transfers, not all systems with "EPP" can support this mode for the Zip drive. Iomega software for Zip includes a parallel port accelerator that can automatically set up both your computer and your Iomega software to use the fastest transfer mode for the Zip drive that is supported by your computer hardware. Under Windows 95/98, you can run the parallel port accelerator by double-clicking on the icon in the Iomega Tools folder on your Start Programs menu. For Windows 3.1, double click on the "Parallel Port Accelerator" icon in your Iomega Zip Tools Windows group. Under DOS, run the OPTPPM1.EXE utility as follows: Step 1: If you have not already done so, install your Zip software package following the instructions in step 10 of the Zip Installation Guide. Step 2: Go to the DOS prompt for drive C: and type: cd \iomega optppm1 NOTE: If you wish to restore the default settings on your system, run "OPTPPM1.EXE /NIBBLE" from the DOS prompt. (This works under Windows 3.1 as well as DOS.)
