My computer locks up when I press Esc to exit the ECU.
If this happens, turn your machine off and then on to reboot. Any
settings you changed before you tried to exit the program have been
registered in the EEPROM and will not be lost.
One of the SCSI devices on my system does not allow termination to be disabled. How
can I attach it to the SCSI bus?
You might be able to attach this device on the end of the SCSI bus so
you do not need to disable termination on it. If this is not possible,
contact the manufacturer about possible work-arounds.
I installed my host adapter board at IRQ12, and it does not work properly. What is
wrong?
Another device such as a mouse may be using IRQ12. Change the
adapter board's IRQ to the default value (11) or to some other value.
See Configure the Host Adapter Parameters on page 3-5.
When I install my host adapter it either does not get automatically added by my ECU,
or an error is reported by the motherboard as not being a valid board, even after
running the ECU.
Verify that you are using the correct
.cfg
file and
.ovl
file for the host
adapter. Also, other EISA boards and their position on the bus could
be causing the board to be misidentified.
Conflicts With Other Options
You will encounter problems if your host adapter and peripheral
devices use overlapping extended BIOS and I/O addresses. To
correct this problem, complete the following:
1
Change the IRQ settings with the ECU.
2
Use the ECU to view BIOS addresses for the host adapter and,
if necessary, change them.
