adapter. But you may need to assign some of these values man-
ually in the Setup program.
Is the host adapter's IRQ or port address in conflict with any
SCSI ID? Again, the PCI bus assigns IRQ, port address, and
BIOS address settings automatically, but you may need to
assign some of these values manually in Setup .
Is each SCSI device, including the channel, set to a unique SCSI
ID? (See SCSI IDs on page 2-14.)
Is SCSI termination set correctly? (See Terminating the SCSI Bus
on page 2-11.)
If your problem is still not resolved, continue with the next section.
BIOS Startup Messages
After you install your host adapter, the host adapter BIOS displays a
message when you boot your computer. Normally, this message lists
the SCSI ID, manufacturer, model number, and other information for
each SCSI device that the BIOS detects. If initialization fails, how-
ever, the host adapter BIOS displays a specific error message fol-
lowed by a BIOS Installation Failure message. Here are some of
these error messages and their meaning:
Device connected, but not ready.
This message appears if the channel receives no answer when it
requests data from an installed SCSI device. The channel skips this
device and moves on to the next device on the bus.
Do the following if you see this message when you request data
from a SCSI drive:
1
Run SCSISelect and access SCSI Device Configuration. Locate
the channel's SCSI ID and set Send Start Unit Command to yes.
2
Exit SCSISelect and request data from the drive again.
3
If the message still appears, follow the drive manufacturer's
instructions to make sure the drive is set to spin up when the
power is
.
ON
Start unit request failed.
The BIOS was unable to send a Start Unit command to the device.
Run SCSISelect and disable Send Start Unit Command for the device.
