Problems with PCI BusLogic SCSI Controller (132657)
The information in this article applies to:
- Microsoft Windows 95
- Microsoft Windows 98
This article was previously published under Q132657 If this article does not describe your hardware-related issue, please see the following Microsoft Web site to view more articles about hardware: SYMPTOMS
If your computer contains a Peripheral Component Interconnect (PCI)
BusLogic small computer system interface (SCSI) controller, either of the
following symptoms may occur:
- Device Manager displays an exclamation point in a yellow circle next to
the PCI BusLogic SCSI controller,
- System performance is not a good as you expect with the PCI BusLogic
SCSI controller.
CAUSE
This behavior can occur if the BusLogic card is not configured as a true
PCI device.
RESOLUTION
To configure the BusLogic card to be a true PCI device, remove the jumpers
in the bottom right corner of the card. If you remove the jumpers,
the card can be enumerated. If you leave the jumpers on on the card, the
card is detected as a legacy device and is not enumerated by the
enumerator. Also, if you leave the jumpers on, the I/O range is set to a
standard address (such as 330, 334, 130, or 134) instead of a standard
high PCI address.
If the version number in the top right corner of the card is -01-4.23K or
later, the card is supported in true PCI mode and Microsoft recommends
that you remove the jumpers.
If the version is earlier than -01-4.23K, leave the jumpers on the card.
MORE INFORMATION
The factory default jumper settings should work, as all cards earlier than
version -01-4.23K were shipped with the jumpers on. However, if the
jumpers are removed from an early card, the device will not work
correctly.
For information about setting the jumpers on the PCI BusLogic SCSI
controller, please contact the manufacturer.
