DOCUMENT:Q141713 08-AUG-2001 [winnt] TITLE :Mkecr5xx.sys Reports Wrong I/O in Registry for SoundBlaster 16 PRODUCT :Microsoft Windows NT PROD/VER:3.5 3.51 OPER/SYS: KEYWORDS:kbnetwork ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Workstation versions 3.5, 3.51 - Microsoft Windows NT Server versions 3.5, 3.51 ------------------------------------------------------------------------------- SYMPTOMS ======== You may experience problems reading compact discs with a CD-ROM drive connected directly to a SoundBlaster adapter if you are using Mkecr5xx.sys with the default base I/O address listed in the documentation for the adapter. CAUSE ===== The base I/O address used by the SoundBlaster adapter is 10 higher than stated in the documentation for these adapters. The base I/O address can be verified by checking WinMSD or the Windows NT Registry. RESOLUTION ========== Reset the base I/O address to a different setting that no other device is using. The address should be chosen so that it is free for 20 address spaces (for example, 0x320-0x33F). STATUS ====== Microsoft has confirmed this to be a problem in Windows NT version 3.51. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
