DOCUMENT:Q150283 08-AUG-2001 [winnt] TITLE :SysKonnect FDDI Cards and Some EISA Computers possible data PRODUCT :Microsoft Windows NT PROD/VER:WinNT:3.5,3.51 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- 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 ======== Computers with an EISA bus that use SysKonnect FDDI network adapters may experience data corruption during some DMA write operations. CAUSE ===== SysKonnect has confirmed that a problem exists in the application-specific intergrated circuit (ASIC) on their FDDI network adapters with model numbers SK-53xx. The problem occurs only if the Bclock signal on the EISA bus is extended beyond 800nS. This condition is known to occur on the following Compaq systems: SystemPro XL ProLiant 2000 ProLiant 4000 ProLiant 4500 RESOLUTION ========== To resolve this problem, please contact SysKonnect technical support for an ASIC revision. In addition to this hardware update, an enhanced Windows NT driver is available from SysKonnect. ====================================================================== Keywords : Technology : kbWinNTsearch kbWinNTWsearch kbWinNT351search kbWinNT350search kbWinNTW350 kbWinNTW350search kbWinNTW351search kbWinNTW351 kbWinNTSsearch kbWinNTS351 kbWinNTS350 kbWinNTS351search kbWinNTS350search Version : WinNT:3.5,3.51 Issue type : kbprb ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
