M ask = 03 PC/AT C op rocessor D river
virtual device driver. The return code is in
D04.
Module-ID = CPDSLIH
I/O Channel Check — 286 was BUS MASTER —
This channel check is usually caused by a
parity error on the 512K bus memory card that
could indicate a bad module on the board.
A temporary solution is to remove the bus
memory card and run the Coprocessor using
ROMP system memory.
Module-ID = PCCDMUL8 RC = -1 J3TDMA
Nonzero return code from -STDMA — This
error indicates that an invalid address or word
count was written to the DMA controller by the
application running on the Coprocessor.
Attempt to determine what the DMA operation
in the application is doing and correct the
invalid address or word count.
Module-ID = PCCVMAIN RC = -1 -MAPSYS
Mapping of system memory failed for relocated
video buffer or queue — This error indicates
there was insufficient memory available for the
MAPSYS operation.
You should be able to request less memory for
the Coprocessor when the PCSTART command
is issued. For example, 512K instead of 640K.
Module-ID = PCCVMAIN RC = -1 -PINPG
Pin page range failed — This indicates that
there was insufficient memory available for the
PINPGS operation.
