allowable ROMNAL setting is $0; the highest allowable is $F. The
value to enter depends on processor speed; refer to your
Processor/Memory Mezzanine Module User’s Manual for appropriate
values. The default value varies according to the system’s bus clock
speed.
Note
ROM Next Access Length is not applicable to the MCPN750.
The configured value is ignored by PPCBug.
DRAM Parity Enable [On-Detection/Always/Never - O/A/N] = O?
Note
This parameter (above) also applies to enabling ECC for DRAM.
L2 Cache Parity Enable [On-Detection/Always/Never - O/A/N] = O?
PCI Interrupts Route Control Registers (PIRQ0/1/2/3) = 0A050900?
Initializes the PIRQx (PCI Interrupts) route control registers in the
IBC (PCI/ISA bus bridge controller). The ENV parameter is a 32-bit
value that is divided by 4 to yield the values for route control registers
PIRQ0/1/2/3. The default is determined by system type. For details on
PCI/ISA interrupt assignments and for suggested values to enter for
this parameter, refer to the 8259 Interrupts section of Chapter 4 in the
MCPN750A CompactPCI Single Board Computer Programmer’s
Reference Guide.

N
DRAM parity is never enabled
O
L2 Cache parity is enabled upon detection. (Default)
A
L2 Cache parity is always enabled.
