Parameter
Size
Description
Bootability
test results
4 bytes
Results of the bootstrap test. Written by the firmware. Field
breakdown by bit:
•
00 = CPU/ATM check. Set when the CPU and ATM are
good.
•
01 = Cable state. Set when cables are present and good.
•
02 = Other zone power state. Set when the power is on in
the other zone.
•
03 = Other zone OpenVMS operating system state. Set
when the other zone is running the OpenVMS operating
system.
•
04 = Other zone CPU/ATM check. Set when the CPU and
ATM in the other zone are good.
•
[31:07] = Reserved for firmware use.
PFN
bitmap
address
4 bytes
Physical address of the PFN bitmap. Initialized by firmware.
PFN
bitmap
size
4 bytes
Size of the PFN bitmap in bytes. Initialized by firmware.
PFN
bitmap
checksum
4 bytes
Checksum of the PFN bitmap. Checksum = integer sum of all
bytes in the PFN bitmap.
System
serial
number
12 bytes
System serial number. 12 ASCII characters. Initialized by
firmware. Copied from the CPU module data EEPROM.
Zone A
DCB offset
4 bytes
Offset to the Zone A DCB. Offset is the byte offset (signed)
from the CCA base. Initialized by firmware.
Zone A
DCB size
4 bytes
Size in bytes of the DCB for Zone A. The size includes the
DCB and any SubDCBs for Zone A. Initialized by firmware.
Zone B
DCB offset
4 bytes
Offset to the Zone B DCB. Offset is the byte offset (signed)
from the CCA base. Initialized by firmware.
Zone B
DCB size
4 bytes
Size in bytes of the DCB for Zone B. The size includes the
DCB and any SubDCBs for Zone B. Initialized by firmware.
