Number: A1TH083190U536 Subject: Adaptec SCSI Controller Abend: Invalid op-code Date: January 23, 1991 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - GENERAL INFORMATION: Configuration: Adaptec 1542-b controller Maxtor 1684-7 SCSI drive. Advanced NetWare 286 v2.15c with Adaptec ASWNOVL.OBJ (Sept 89) VADD PROBLEM: When the operating system is loading, the file server would hang with this error: Abend: Invalid op-code running process DISK SOLUTION: Change the Default DMA Channel 5 to DMA Channel 0. This is accomplished by jumpers on the Adaptec controller. There is a new ASWNOLV.OBJ (dated 01/05/90) available from Adaptec that might also resolve issue, but this is not confirmed.
