DOCUMENT:Q137967 08-AUG-2001 [winnt] TITLE :STOP 0x00000077 with Two MYLEX DAC 960 in the Same Computer PRODUCT :Microsoft Windows NT PROD/VER: 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 ======== On a computer that has two MYLEX DAC 960 controllers, Windows NT hangs or traps randomly with the following stop error: STOP 0x00000077 (0x00000103, 0xc0000185, 0x00000001, 0x00005000) The STOP error and the second parameter (0xc0000185) are always the same, the other parameters may or may not vary. CAUSE ===== The MYLEX controllers go off-line randomly. Although the MYLEX controller is on the Hardware Compatibility List (HCL) for Windows NT 3.5 and 3.51, a multiple-controller configuration was not tested. RESOLUTION ========== Upgrade the firmware of the MYLEX controllers to version 2.16. This firmware revision can be obtained from MYLEX Corporation. These controllers can handle multiple devices and several levels of RAID. Therefore, you may be able to meet your configuration needs with only one MYLEX DAC 960 controller installed in your computer. MYLEX DAC 960 controllers are manufactured by MYLEX Corporation, a vendor independent of Microsoft; we make no warranty, implied or otherwise, regarding this product's performance or reliability.
