Using Drive Image with SCSI Hard Disks
To use Drive Image on a SCSI hard drive, you must have a SCSI controller card that
supports software Interrupt 13. Most SCSI controller cards let the user enable software
Interrupt 13 support in the BIOS through the card. If your SCSI controller card does not
allow you to set it to use software Interrupt 13, Drive Image will not work on drives
attached to your SCSI adapter. Contact the manufacturer of the SCSI adapter to determine
if your adapter can support software Interrupt 13. As a general rule, if FDISK can be used
to partition the drive, you can use Drive Image.
Using Drive Image with Drive Overlay Software
Drive overlay software is needed, such as Disk Manager or EZ-Drive, if the system has an
older BIOS and the disk copy is being made from IDE to IDE or IDE to SCSI.
IMPORTANT!
If copying SCSI to SCSI, the older BIOS does not come into play because
SCSI has its own translation mechanism.
This section provides information on both IDE and SCSI hard drive installations. The
following are scenarios which outline, step-by-step, the installation procedures for a
variety of system configurations. Each scenario assumes that all the bulleted items listed at
the beginning apply for the system configuration. To ensure you are choosing the right
procedure, choose the scenario that matches your system configuration completely.
Scenario 1
• The system has a BIOS that does not support drives over 504 MB in size.
• The source drive is an IDE drive that is smaller than 504 MB. It does not have a drive
overlay program.
• The destination drive is an IDE drive that is larger than 504 MB and needs to have a
drive overlay program to be recognized by the older BIOS.
Steps
1
Install the destination drive as the master and the source drive as the slave and run the
auto-detect in the BIOS.
2
Restart the computer with the drive overlay boot disk.
3
Install the drive overlay program to the destination drive that is now set as the master
(check with manufacturer).
