SYMPTOMS
Windows NT will not start on an Olivetti LSX 5025/E using the Adaptec ARROW.SYS SCSI driver.



CAUSE
There is an Input/Output (I/O) memory conflict between the ARROW.SYS driver and the Olivetti UPS driver. The Adaptec Arrow control chip uses the I/O memory address range of 0xC00 to 0xCF0 and the Windows NT Arrow driver reserves the range 0xC00 to 0xCFF. The Olivetti LSX 5025/E computer uses the I/O memory address range 0xCF8 to 0xCFF to map an internal serial port, generating the conflict between the two drivers.



STATUS
Microsoft has confirmed this to be a problem in Windows NT and Windows NT Advanced Server version 3.1. This problem has been corrected in the latest U.S. Service Pack for Windows NT and Windows NT Advanced Server version 3.1. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
