SYMPTOMS
The Scsiport driver might ignore the registry overrides that are specified for a SCSI miniport driver and instead use the default parameters.



CAUSE
The Scsiport driver can read registry values of lengths up to 255 characters. If a value is longer than 255 characters, the Scsiport driver stops reading registry keys and ignores the rest of the keys.

MORE INFORMATION
SCSI miniport drivers can receive parameters and pass override values to the Scsiport driver through the registry. The Scsiport driver reads these keys and takes the appropriate actions. If the registry values are not read by the Scsiport driver, it uses the default values instead of the specified override values. The hotfix that this article describes resolves this problem.
