Installing Drivers And Build Tool For Mirage on page 21 for more details NOTE 3 3 3 3 1 Setup For SG Indy Hosted Systems The Mirage emulation HD can be either the Mirage s internal HD or any SCSI hard disk connected to the Mirage s Expansion Port The emulaton HD is defined using the DRIVE ID setting The factory default is the Mirage s internal HD 0 The Mirage s emulation HD must be in IBM DOS format with a 32 bit DOS FAT See The SCSI Menu on page 63 and The Mirage s Two SCSI Buses on page 71 for more details Installing Drivers And Build Tool For Mirage This section shows you how to install the software and drivers necessary to use the Mirage with the Indy Installing From A tar File If you have received your Mirage software as a tar file then you will need to unpack the files before you can install them on your Indy 1 Make a temporary directory For example type mkdir tmp cp 2 Copy the tar file into the temporary directory 3 Change to the temporary directory cd tmp cp 4 Untar the installation files tar xvf tmp cp X tar where X tar is the name of the tar file 5 Repeat steps 2 and 3 for all of the TAR files supplied Now continue with Installing The Indy Software but inform the Software Manager that the files to be installed are in the temporary 21 Setup For SG Indy Hosted Systems 3 3 2 22 directory tmp cp for the above example instead of on a CD
5. 17 3 Troubleshooting Disk And General Errors Disk And General Errors At any time during emulation file selection or computer access the Mirage may display one of the following messages Hi The emulation HD chosen using the DRIVE ID setting does not appear to be correctly formatted or is corrupt Use DOS compatible disk tools such as CHKDSK or SCANDISK from a PC to examine and repair the emulation HD You can format it using the standard DOS or Windows format from a PC DOS 5 or above If this message appears when the computer tries to access the Mirage then the Mirage s internal cables might have been loosened in shipping Remove the Mirage s case top and gently push each visible ribbon cable into its socket For more details on opening the Mirage see Removing The Personality Module on page 76 The emulation HD defined using the DRIVE ID setting is not responding Check that you have set DRIVE ID to the correct drive the drive is powered on and that all cabling is secure The Mirage has been unable to read a file for an unknown reason Contact the supplier of your Mirage for more details The Mirage couldn t start the emulation HD Turn off the Mirage and check that the emulation HD is powered on and that all cabling is secure 125 Troubleshooting Disk And General Errors 126 The Mirage was unable to read data from the emulation HD Turn off the Mirage and check that the emulation is p
