L2 Cache Parity Enable [On-Detection/Always/Never - O/A/N] = O?
PCI Interrupts Route Control Registers (PIRQ0/1/2/3) = 0A0B0E0F?
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 four 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 the
MVME2600 Programmer’s Reference Guide, listed in

Configuring the VMEbus Interface
ENV asks the following series of questions to set up the VMEbus interface
for the MVME2300/MVME2600/MVME3600 /MVME4600 series
modules. To perform this configuration, you should have a working
knowledge of the Universe ASIC as described in the Programmer’s
Reference Guide.

VME3PCI Master Master Enable [Y/N] = Y?
PCI Slave Image 0 Control = 00000000?
The configured value is written into the LSI0_CTL register of the
Universe chip.

PCI Slave Image 0 Base Address Register = 00000000?
The configured value is written into the LSI0_BS register of the
Universe chip.
Universe chip.
O
L2 Cache parity is enabled upon detection. (Default)
A
L2 Cache parity is always enabled.
N
L2 Cache parity is never enabled.
Y
Set up and enable the VMEbus Interface. (Default)
N
Do not set up or enable the VMEbus Interface.
