Note:
nected to the MiniSCSI EPP because your
computer cannot boot from a device con-
nected to the parallel port. The MiniSCSI
EPP device drivers must be loaded during
the boot process from another device.
Make sure all cables are properly connected.
Make sure all SCSI devices have unique SCSI IDs.
Make sure the SCSI bus is properly terminated.
No SCSI Host Adapter Detected Message Appears at Bootup
The MiniSCSI EPP requires SCSI TERMPOWER to
operate. Check for SCSI device TERMPOWER:
Use a voltmeter to measure the voltage available
between pin 38 and ground on the SCSI device's
connector (see SCSI Connector Pinouts). Make sure
the SCSI device(s)
approximately +5 volts. Very low or no voltage at
pin 25 indicates a problem with termination
power; this condition disables the adapter.
Plug a printer into the printer passthrough port. If
the printer can print, you have correct
TERMPOWER.
No SCSI Functions in Use Message Appears at Bootup
The software driver is looking for a different device.
For example, you may have the CD-ROM driver
loaded, but you are trying to work with a hard disk
drive or vice versa. Each Adaptec software driver
recognizes the existence of all SCSI devices attached
to the SCSI chain but only works with the device for
which it is written to communicate. Install the correct
driver or remove an unwanted driver from your
config.sys file with a text editor program.
Network Installations
If your computer is part of a network installation,
your printer port may be redirected to a network
printer. For instance, Novell
uses the capture command for this purpose. If this is
the case, the software will not detect the hardware at
