IOMEGA DRIVES AND WINDOWS 95
(Source Iomega FaxBack document #: 2049  9/8/95
                             
Windows 95 has 2 modes of operation Real(MSDOS) Mode and Protected Mode. 
  
     Real (MSDOS) Mode - Real mode operation is Windows 95 MSDOS
     compatibility mode.  This is the slower of the two modes.  This mode is
     used when devices are configured with MSDOS device drivers and
     Protected Mode drivers are not available.
     
     Protected Mode - Protect mode operation is the fastest mode of   
     operation under Windows 95, it is also the preferred mode of operation. 
     This mode uses built in 32-bit drivers, sometimes called Mini-Port drivers,
     to support  devices including:  Hard Drive Controllers, Video Controllers,
     SCSI Controllers, etc..
     
Any device that does not have built in support, or the manufacturer does not
supply protected mode drivers can use the Real Mode (current MSDOS) drivers.
Iomega has protected mode drivers available for the PC2, PC1600, PC1616,
PC800, PPA-3, and the Zip Zoom SCSI adapters.    

Iomega Products and Protected Mode Operation
Windows 95 will support Iomega drives in protected mode if there is a protected
mode driver for the SCSI adapter.  Windows 95 has built in protected mode
drivers for 3 Iomega SCSI adapters.  The PC1600, the Zip Zoom SCSI
accelerator, and the PC2.  Windows 95 will load the protect mode drivers
automatically if these adapters are installed previous to Windows 95.  If the
protect mode drivers do not load automatically you will have to install and
configure these drivers manually.  To add a supported SCSI adapter use the
Add New Hardware program in the Control Panel and follow the instructions later
in this document. The drives should work attached to any SCSI adapter that has
a built in protected mode driver.
  
If you use the protect mode drivers with Iomega drives, you will not be able to
run the DOS/Windows versions of Zip Tools or Iomega utilities.  A Windows 95
version of the Iomega Tools is required (See Windows 95 Upgrade Kit below).

Where To Find Windows 95 Drivers
The protected mode drivers for the Zip Parallel Port(PPA-3) are available on the 
Windows 95 CD-ROM.  It is located in the \DRIVERS\STORAGE\IOMEGA 
directory.  To install, copy the PPA3.MPD and PPA3.INF to a floppy and follow
the installation instructions later in this document.  The protected mode drivers
for the Zip Zoom and PC1600 are included with Windows 95, use the Adaptec
driver labeled  Adaptec AIC-6X60 ISA Single-Chip SCSI Controller .  The
protected mode driver for the PC2 adapter is included with Windows 95, use the
installation instructions below for help installing the PC2 adapter.  The protected
mode drivers for all Windows 95 supported Iomega SCSI adapters are currently
available via on-line services.  They are available on Iomega s BBS, America
Online, Microsoft Network and Iomega’s Internet FTP site.  The filename to
download is WIN95.EXE, this is a self extracting file.  Please note that this file
includes the drivers only.  The Iomega tools utilities must be purchased
separately (see below).  Use the installation instructions later in this document
for help installing the drivers.

Installation Instructions for the Iomega Windows 95 Protected Mode Drivers
These instructions are provided to help you install the Protected mode drivers.  
 
In preparation of installing the drivers, you should first remove the Iomega DOS drivers if you are using them. Edit your CONFIG.SYS file and place an REM command in front of any drivers that reference the IOMEGA or OADDOS directories. Edit your AUTOEXEC.BAT file. Place an REM command in front of any driver that has references the file GUEST.EXE.
	Example: 
		LH C:\ZIPTOOS\GUEST.EXE
	Change To:
		REM LH C:\ZIPTOOLS\GUEST.EXE
	Once you have done this, proceed with the installation of our drivers. Please follow the directions carefully and make sure that you follow the directions carefully and that you don’t try to skip any steps.

1. It is best to extract the file in an empty directory. Copy all the driver files to a floppy disk.  
a. 	Switch to the directory were the WIN95.EXE file is located. 
b. 	Run the file WIN95.EXE. The file will extract about 8 files which are your drivers.
c. 	Copy those files to a floppy.  At a DOS prompt type:  COPY  *.*    A: <enter>  (replace A: with B: if copying to B:)
          
2.  Run the Add New Hardware program from the Control Panel.
a.  Click on the  Start  Button.
b.  Highlight the Settings option.
c.  Click on Control Panel.
d.  Double click on Add New Hardware.
 
3.  Click  Next  until the Add New Hardware Wizard asks if you want windows to
search for new hardware, click on  NO  and select  Next .          
  
4.  From the list of Hardware select SCSI Controllers, and then click Next.
  
5.  Click on the  Have Disk  button.
     
6.  Select the floppy drive letter(A:\ or B:\) and select  OK .
  
7.  Highlight the Iomega Adapter that you are installing, click  Next  to continue.
  
8.  Click  Finish  to complete the installation.
  
9.  Reboot the computer.
  
When the system restarts, the Iomega drive should be assigned a drive letter
and will be ready to use.  The Iomega SCSIUTIL and Zip Tools programs will not
run when the protected mode drivers are loaded, they require the Iomega real
mode drivers be loaded.

Troubleshooting
If the Iomega drive is not assigned a drive letter, you will need to adjust the SCSI adapter settings for the Protected Mode driver.  Make sure the driver loaded properly:
  
1.  Right mouse button click on the My Computer icon.
  
2.  Click on the  Properties  option.
  
3.  Click on the  Device Manager  tab.
  
4.  Double click on the  SCSI Controllers  line.
Does the Iomega adapter driver icon have a Yellow circle with an exclamation
point on it?  This means that the resources for the Iomega SCSI adapter are not
set properly.  Change the Port Address and/or Interrupt resource settings to
match the switch or jumper settings on the SCSI adapter.  Once these resource
settings match, the driver will load and assign the Iomega drive a letter.
  
5.  Highlight the Iomega Adapter that you just installed, and then click on the
Properties  button.
 
6.  Click on the  Resources  tab.
  
7.  Verify that the  Input/Output Range  and the  Interrupt Request  options are
set to the appropriate values.
  
8.  If either option is incorrect, highlight the option and click on the  Change
Setting  button.  Select the correct setting and click on  OK .
  
9.  Click  OK  to close the adapter window.  Click  OK  to close the System Properties window.
  
10.  Reboot. 

More info!
These are the options available for the PPA3 Mini Port Driver (MPD). These options must be added to the settings line under the property sheet of the SCSI adapter. The PPA3 is the adapter incorporated into the Parallel Port Zip drive.

/SPEED: x          
   valid values: 1 to 6

/MODE: x
  valid values:  NIBBLE (for uni-directional or AT ports)
                        BIDIR   (for Bi-directional or PS/2 ports)
                        FAST
                        EPP
NOTE: EPP is used when there is a setting in the computers BIOS to designate the port as EPP, other wise FAST is the enhanced parallel port mode.
