============================================================================ AST RESEARCH, INC. SOFTWARE BULLETIN # 0150B 2-14-95 ============================================================================ MANHATTAN SMP EMPIRE MULTITHREADED BTLD FOR SCO UNIX/ODT Production Release: 1.06 Available: July 1994 Part Number Description 910727-321 3.5" diskette 1 of 1 Revision: A This release contains the following problem resolutions and enhancements: PROBLEMS RESOLVED: Resolved a problem with Exabyte 8 mm tape drives crashing the system. ENHANCEMENTS: Enabled up to 60 concurrent I/O requests on the DAC960. Added support for the single channel version of AST's Empire (DAC960) controller AST P/N 230624-001. Modified the configuration printout at boot time (%adapter line). It now identifies the number of channels and number of targets per channel. The "features" string has also been removed. Added a watchdog mechanism to guard against frozen DAC960 mailboxes and to issue an appropriate warning. Enabled Input/Output requests to be returned to SCO's mscsi layer when they're unserviceable. The potential for this possibility exists if the HW mailbox is frozen or if the request itself is corrupted.
