This article was previously published under Q160667 SYMPTOMS
When you attempt to write a program or device driver that calls the
following APIs, you may encounter the following errors:
ScsiPortReadRegisterUshort()
Specifically, miniport drivers written to use these APIs may fail to
load.
ScsiPortReadRegisterULong() CAUSE
These APIs are documented as being exported by SCSIPORT.PDR. However, due
to a problem in SCSIPORT.PDR, these APIs are not correctly exported.
RESOLUTION
This issue is resolved by the following updated file for Windows 95, and
later versions of this file:
SCSIPORT.PDR version 4.00.951 dated 10/26/95 23,165 bytes STATUS
