Ch 2: System Environment Setting
Hitachi VisionBase 8880R Server 49
•
A message such as the following is displayed when you add or change an extended board:
“This operation cannot be completed because of a resource conflict.Due to ISA I/O aliasing,the I/O port(s)
starting at XXXX conflicts with XXXX card I/O port(s) starting at XXXX.”
Explanation: As conflict occurs between I/O port start address (XXXX) and start address (XXXX)
because of I/O aliasing for the ISA card. I/O aliasing refers to recognition of different
addresses as the same address because only lower 10 bits (0–3FFh) in the I/O port
addresses are effective. For example, I/O port addresses “100h” and “500h” are
recognized as the same address; therefore only “100h” must be set.
Solution: Take one of the following actions:
•
Choose other values for resources for the extended board to be added.
•
In the ICU, do not set the resources for the extended board to be added.
(However, settings for the extended board is required after the ICU is terminated.)
•
If the above message is displayed only within one extended board, only set the
lowest-order value.
Restrictions on the ICU
•
You cannot use extended board not supported by the system equipment.
•
The communication board PC-CH2100 cannot use DMA3, so do not set DMA3 for it. In the ICU some windows
and dialog boxes might have portions that are not easy to see because characters are displayed in black in gray
background.
•
While you are operating the ICU, sometimes characters might not be displayed properly or part of some ruled
lines might be missing in some windows or dialog boxes, but nothing is wrong with the operation of the ICU.
Referring to diagrams of windows and dialog boxes in this manual, keep on operation.
•
Japanese characters cannot be used for board names in “Add Card”. Use alphanumeric characters only.
•
The ICU program disk must not be shared between multiple systems. If you use the disk on different system
equipment, names of ISA boards incompatible with Plug and Play might be changed to “Unknown Card” or
displayed improperly.
•
Depending on the PCI board, “PCI Card: Unknown Card” is displayed in the [ISA Configuration Utility]
window. This is not an abnormality.
•
Although you cannot change resources for PCI boards, you can specify whether or not to invalidate or lock
resources. However, when you restart the system equipment, the setting will be initialized to Invalid or
Unlocked.
•
In some types of machines in which an ISA board incompatible with Plug and Play is installed, use of the ICU
causes “Unknown Card” to be displayed.
•
Make sure not to change settings for the IDE controller.
•
In the [Memory] list box “1FFFFF” is always displayed; however, the actual memory capacity is correctly
recognized. The end address of an address range might not be entirely displayed because of the number of total
digits is too large for the display range. This is not an error.
