+.Sh NAME
+.Nm memc
+.Nd MVME162-MVME177 Memory Controller Chip
+.Sh SYNOPSIS
+.Cd "memc* at mainbus0"
+.Sh DESCRIPTION
+The
+.Nm
+devices are used on MVME162, MVME167, MVME172 and MVME177 boards
+to manage one or more DRAM modules.
+.Pp
+Depending on the type of DRAM module fitted, the device will
+either be a MEMC040 device or an MCECC device. The former manages
+a Parity DRAM module while the latter manages an ECC DRAM module.
+.Sh DIAGNOSTICS
+.Bl -diag -compact
+.It memc0 at mainbus0.
+This is the normal autoconfiguration message indicating that the
+Memory Controller Chip has been found and attached to the main processor
+bus.
+.It memc0: Correctable error on CPU read access to 0x12345678.
+This indicates that an MCECC memory controller detected and corrected
+a single bit error in one of the DRAM banks. There are a few variations
+on the message where "CPU" can be replaced with "Peripheral Device"
+or "Scrubber", and "read" can be substituted for "write".
+This message is followed by some more details which can help pin-point
+the error...
+.It memc0: ECC Syndrome 0x23 (DRAM Bank C, Bit#16).
+Pin-points exactly where the error occurred.
+.It memc0: Uncorrectable error on CPU read access to 0x12345678.
+Errors like this have the potential to corrupt data. As such, it is
+likely the system will panic very soon afterwards.

+.Xr mvme68k/mainbus 4
+.Sh BUGS
+The
+.Nm
+driver does not yet fully support the MEMC040 (Parity) version
+of the device.
