Installed Host Adapters

Adaptec EZ-SCSI has scanned your system looking for installed Adaptec host adapters. If it found any, it lists their model number and I/O port address or slot number in the lower half of the window.

If no Adaptec host adapter are listed, you should exit EZ-SCSI and install an Adaptec host adapter. Then connect your SCSI devices to the host adapter SCSI bus and run EZ-SCSI again.


Installed SCSI Devices

Adaptec EZ-SCSI has scanned your system looking for installed SCSI devices. It lists the following information about each device it has found:

•	SCSI ID

•	Manufacturer

•	Model Number

Scroll up or down, if necessary, to view all devices on the list.

If a device does not appear on the list, make sure the device is powered on, that it is terminated correctly, and that it does not have the same SCSI ID as another device on the SCSI bus.


Copying the Files

Adaptec EZ-SCSI will automatically copy the drivers and utilities from the Installation diskettes to your hard disk.

•	Press Install if you want EZ-SCSI to copy the files to the default directory listed on your screen. (EZ-SCSI will create this directory if it does not already exist.)

•	Press Set Location if you want EZ-SCSI to copy the files to a different directory and/or drive, then enter the full path name for this directory.


The mscdex.exe File

Adaptec EZ SCSI has found a CD-ROM drive in your system. A special file named mscdex.exe is needed for your CD-ROM to work properly. mscdex.exe is not included with the installation diskette and must be loaded from another source.

You must either cancel this option by pressing Cancel or type the path where EZ-SCSI can find mscdex.exe -- for example,  a:\  or  b:\

If you do not have mscdex.exe, cancel this option and get the file from your system vendor. You can run EZ-SCSI again later when you have mscdex.exe.


Drive Letters for CD-ROM Drives

If the ASPI disk driver (aspidisk.sys) is not already installed when you run Adaptec EZ-SCSI, EZ-SCSI may not know that some drive letters are already assigned to hard disk drives and may incorrectly suggest one of these drive letters for the CD-ROM drive.

If you know that some drive letters are already assigned, simply select the correct drive letter for your CD-ROM drive in the box at the top of this screen. If you are not sure whether EZ-SCSI is suggesting the correct drive letter for the CD-ROM drive, finish running EZ-SCSI and then run it again. Since aspidisk.sys will now be installed, EZ-SCSI will know which drive letters are assigned to disk drives and will suggest the correct letter for the CD-ROM drive.

If your system has multiple CD-ROM drives, only enter a drive letter for the first one. EZ-SCSI automatically assigns drive letters to the others. For example,if your system has three CD-ROM drives and you assign drive letter F to the first one, EZ-SCSI assigns G and H to the other two drives.


Additions to config.sys

This screen lists the entries that must be added to your config.sys file. config.sys, a text file in the root directory of your boot disk, contains configuration commands that DOS reads when you boot up your system. The additional entries will enable the appropriate device driver(s) for your system configuration. If you wish, you can edit the entries by clicking the Edit button. (For example, you might want to add other command line options.)

You have several choices of what to do with the config.sys entries:

1.	Let Adaptec EZ-SCSI change config.sys automatically. You should choose this option unless there is some reason why you don't want your config.sys file changed right now. Before EZ-SCSI changes config.sys, it saves a backup copy of the unchanged file called config.bak.

2.	Save a copy of the modified config.sys under another name. You can change the suggested path and filename if you wish. If you choose this option, you must be sure to add the entries to your config.sys file later. Otherwise your system will not recognize the Adaptec host adapter(s) when your system boots up.

3.	Do not enter or save the config.sys changes at all. This choice will also prevent your system from recognizing the Adaptec host adapter, unless you add the config.sys entries yourself.


Changing config.sys Entries

The additional config.sys lines appear at the top of this window. The scrollable area at the bottom of the window shows all the entries in your config.sys file. You can examine the file or enter editing changes to any command. For example, you may want to add other command line options to the new lines for the ASPI manager and device drivers.

When you have finished entering changes, press OK to save the changes immediately to config.sys and continue with installation. Or press Cancel Edit to cancel your editing changes and return to the previous screen.

If you make changes, EZ-SCSI saves a backup copy of the unchanged file as config.bak.


Additions to autoexec.bat

This screen lists the entry that must be added to your autoexec.bat file. autoexec.bat, a text file in the root directory of your boot disk, contains configuration commands that DOS reads when you boot up your system. The additional entry will enable the mscdex.exe utility, which is required in order to run your CD-ROM drive. If you wish, you can edit the entry by clicking the Edit button. (For example, you might want to add other command line options.)

You have several choices of what to do with the autoexec.bat entry:

1.	Let Adaptec EZ-SCSI change autoexec.bat automatically. You should choose this option unless there is some reason why you don't want your autoexec.bat file changed right now. Before EZ-SCSI changes autoexec.bat, it saves a backup copy of the unchanged file called autoexec.bak.

2.	Save a copy of the modified autoexec.bat under another name. You can change the suggested path and filename if you wish. If you choose this option, you must be sure to add the entry to your autoexec.bat file later. Otherwise your CD-ROM drive will not work.

3.	Do not enter or save the autoexec.bat changes at all. This choice will also prevent your prevent your CD-ROM drive from working, unless you add the autoexec.bat entries yourself.


Changing autoexec.bat Entries

The additional autoexec.bat line appears at the top of this window. The scrollable area at the bottom of the window shows all the entries in your autoexec.bat file. You can examine the file or enter editing changes to any command. For example, you may want to add other mscdex.exe command line options.

When you have finished entering changes, press OK to save the changes immediately to autoexec.bat and continue with installation. Or press Cancel Edit to cancel your editing changes and return to the previous screen.

If you make changes, EZ-SCSI saves a backup copy of the unchanged file as autoexec.bak.
