SCSIProbe is a Control Panel (cdev) useful for identifying and mounting devices connected to your SCSI bus. With SCSIProbe you can determine the device type, vendor, product and version for every device connected to your bus. SCSIProbe also includes a startup extension (INIT) that, when enabled, can mount volumes without having to access the cdev. SCSIProbe is System 7 compatible and balloon help is available for assistance.
INSTALLING:
To install SCSIProbe, simply drag the icon into your System Folder. To use SCSIProbe under System 6.x.x, select ╥Control Panel╙ from the Apple menu and select the SCSIProbe icon. Under 7.x.x, open the ╥Control Panels╙ folder (inside the System Folder) and double-click the SCSIProbe icon. Upon opening, SCSIProbe will display a list showing all available devices connected to your SCSI bus:
╩
If a device is detected at a particular SCSI ID but no information about that device is available, a ╥Ñ╙ symbol signifying ╥No Data╙ will be shown in the Type column for that ID.
To refresh the list to reflect any changes that may have occurred since SCSIProbe was opened, click the ╥Update╙ button (typing the letter ╥U╙ or hitting ╥Return╙ will have the same effect). It is also possible to reset the bus by holding down the option key, which will cause the ╥Update╙ button to change to ╥Reset╙, and clicking the ╥Reset╙ button. NOTE: It is recommended to reset the bus only when a device does not appear to be responding correctly.
To mount volumes to the desktop that are currently not mounted, click the ╥Mount╙ button (typing the letter ╥M╙ or hitting ╥Enter╙ will have the same effect). In order for SCSIProbe to mount a volume, it must first be displayed in the list.
OPTIONS:
SCSIProbe can mount volumes without having to access the cdev, close device drivers when ejecting removable media and mount volumes during startup. To enable any of these features, click the ╥Options╔╙ button (or type the letter ╥O╙). The following dialog will appear:
╩
MOUNTING
To enable the Volume Mounting Init, click the top checkbox and enter a ╥Hot Key╙ sequence. A ╥Hot Key╙ can be any combination of modifier keys (Command, Option, Shift or Control) and another key. After closing this dialog with the ╥OK╙ button, anytime the ╥Hot Key╙ is typed SCSIProbe will scan the SCSI bus and attempt to mount volumes currently not mounted.
EJECTING
The second option, when enabled, will close device drivers when ejecting removable media (SyQuest, Bernoulli, etc.). By enabling this option, SCSIProbe will remove the driver associated with disk that was just ejected, freeing the SCSI ID for a new driver. When a new cartridge is inserted, the driver from that cartridge will be loaded into the available ID. This will insure that the correct driver always used for each cartridge.
This option is useful when working with cartridges initialized with a variety of formatting utilities. If all cartridges you work with have been initialized by a single vendor's utility, this option should be disabled.
If the driver fails to close, SCSIProbe will display a dialog indicating that the driver is still installed:
╩
MOUNT AT STARTUP
The third option, when enabled, will automatically mount volumes during startup. This feature is useful when there is a drive on your bus that is slow in becoming ready and the Mac OS fails to recognize it. SCSIProbe will scan your bus when its INIT is opened and mount all volumes currently not mounted.
FEATURES:
SCSIProbe contains a number of features that are not immediately apparent. These features include: visually identifying devices, sizing data fields, renaming the Macintosh model name, and choosing which bus to view on machines that support multiple SCSI buses.
IDENTIFYING
To visually identify what device is at a given SCSI ID, click on the SCSI ID of the item you want to identify. SCSIProbe will attempt to light the LED on the device located at this ID (this feature does not work with all devices, but does work with most drives).
SIZING
Some SCSI devices return more information than fits into the default field size. To change the size of the field, click on the line separating the fields, drag it to the left or right and release the mouse. The data will be redrawn to fit into the new field size:
╩
To return the field to its default size, hold down the ╥Option╙ key and click on the line.
RENAMING
To rename the machine name (and optionally add or remove the word ╥MACINTOSH╙), click on the product name. The following dialog will appear:
╩
Type a new name in the edit field and determine if you want the word ╥MACINTOSH╙ to precede the name. Click the ╥OK╙ button to save changes and the new name will appear in the SCSIProbe window.
This dialog will also appear when SCSIProbe starts up on a Macintosh model that is currently not in its list of models. A similar dialog will also appear when it locates a SCSI device type it does not recognize, allowing you to enter a name for the new type.
BUS SELECTING
For Macintosh models that support multiple SCSI buses (currently Quadra 900 & 950 and PowerBook Duo w/Duo Dock), you can choose which bus to view. To choose a bus, click on ╥ID╙ and select a bus from the popup menu. Once the internal or external bus is selected, all options (update, mount, and identify) only apply on that bus. When ╥Both╙ is selected, the SCSI manager will determine which bus the option applies to.
