- According to the sbic manual, this means : "An unexpected information phase was
- requested. MCI define the SCSI bus phase with is requested. This is typically
- caused by a phase change before the Transfer Count has reached zero or by
- an unexpected phase sequence occurring during a Select-and-Transfer command."
-
- MCI is 0x49 & 0x7, thus %001, which says it's a Data In phase.
-
- So, I can't tell what might happen, this is what the controller chip
- detects.
-
- Since it's a rather strange problem, perhaps you'd have some luck replacing
- the SCSI controller chip against a newer revision? There are some bizarre
- oddities with the used WD/AMD chip, and certain revisions...
