CyberStorm 040 SN# B400506 - B400569 and CyberStorm 060 SN# B002827 - B003065 are affected by several DMA related problems due to a slight difference in the electrical specifications of certain parts caused by supplier change.

- does not work in the A4000T with RAM installed on the CyberStorm
- in an A4000 with a Fastlane or a A4091 SCSI controller installed, peripherals connected to the SCSI bus are not recognized
