DOCUMENT:Q130481 08-AUG-2001 [winnt] TITLE :CMD Technology PCI-0640x IDE Controller Requires New Driver PRODUCT :Microsoft Windows NT PROD/VER:winnt:3.5,3.51 OPER/SYS: KEYWORDS:kb3rdparty kbhw kbHardware ====================================================================== ------------------------------------------------------------------------------- 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 that use CMD Technology's PCI0640x IDE controller chip to control devices on both IDE channels may stop responding (hang) or experience data loss when running Windows NT 3.5 or 3.51 without CMD Technology's Windows NT 3.5 driver. This problem does not occur on computers with only one IDE channel. The CMD PCI-0640x IDE controller chip set can be identified on the motherboard by looking for a LSI chip that has the CMD logo and labeled PCI- 0640x x=A,B,... It is near the connectors used to attach the IDE drives. The following computers contain this chip: AMI Atlas PCI AST Bravo MS-T P/75 Asus tek 90mhz AT&T Globalyst 360, 380, 620, and 630 Dell Optiplex 90 Dell Optiplex XMT 5120 Digital (DEC) Starion 700i DEC (Digital) Venturis 466 HP vectra VL series 3 Micron P5-90 Micron P5-100 NEC Image P90 RESOLUTION ========== Substitute CMD Technology's Windows NT 3.5 driver for the Enhanced IDE driver supplied with Windows NT. CMD's Windows NT 3.5 driver may be downloaded from CMD Technology's bulletin board system. The BBS number is (714) 454-1134. Look for the file 640XNT35.ZIP. Users also may obtain the driver from their reseller. Microsoft has modified the Windows NT version 3.51 file, ATAPI.SYS, to correct this problem. STATUS ====== Microsoft has confirmed this to be a problem in Windows NT versions 3.5 and 3.51. A fix to this problem for version 3.51 is in development, but has not been regression-tested and may be destabilizing in production environments. Microsoft does not recommend implementing this fix at this time. Contact Microsoft Product Support Services for more information on the availability of this fix. The product discussed here is manufactured by CMD Technology, Inc., a vendor independent of Microsoft; we make no warranty, implied or otherwise, regarding the product's performance or reliability.
