AST RESEARCH TECHNICAL BULLETIN TB-0292 8/11/87 ASTUTE/DMA Test When running ASTUTE diagnostics, (version 1.02 or 1.1) some customers may experience a "DMA Controller Test" failure. AST is aware of the failure. Rarely is the failure indicative of an actual "Hardware failure". The test preceding the "DMA Controller Test" is the "DMA Page Register Test". If the Premium 286 is in good operating condition and passes the "DMA Page Register Test", there is no reason to suspect a DMA hardware failure.
