Computer Hangs

•  Check SCSI parity for consistency and be sure SCSI termination is set correctly. See 'Termination (Devices)',   'Termination (AHA2940/2940W Adapters)' and 'Termination (for Multiple-Computer Configurations)'
•  Check cable length and integrity.
•  If the host adapter LED remains on when the computer hangs, the host adapter may be interfering with the  operation of the computer. It may not support First-Parity DMA (that is, Bus Master) data transfers.
