Power-On Self-Test (POST) Indicators
------------------------------------

200 IPL attempted with keylock in the Secure position.
201 IPL ROM test failed or checkstop occurred (irrecoverable).
202 Unexpected machine check interrupt.
203 Unexpected data storage interrupt.
204 Unexpected instruction storage interrupt.
205 Unexpected external interrupt.
206 Unexpected alignment interrupt.
207 Unexpected program interrupt.
208 Unexpected floating point unavailable interrupt.
209 Unexpected SVC interrupt.
20c L2 cache POST error. (The display shows a solid 20c for 5 seconds.)
210 Unexpected SVC interrupt.
211 IPL ROM CRC comparison error (irrecoverable).
212 RAM POST memory configuration error or no memory found (irrecoverable).

217 End of boot list encountered.
218 RAM POST is looking for good memory.
219 RAM POST bit map is being generated.
21c L2 cache is not detected. (The display shows a solid 21c for 2 seconds.)
220 IPL control block is being initialized.
221 NVRAM CRC comparison error during AIX IPL(key mode switch in Normal mode).
Reset NVRAM by reaccomplishing IPL in Service mode. For systems with an
internal, direct-bus-attached (DBA) disk, IPL ROM attempted to perform an IPL from
that disk before halting with this operator panel display value.
222 Attempting a Normal mode IPL from Standard I/O planar-attached devices specified
in NVRAM IPL Devices List.
223 Attempting a Normal mode IPL from SCSI-attached devices specified in NVRAM IPL
Devices List.
224 Attempting a Normal mode IPL from 9333 subsystem device specified in NVRAM IPL
Devices List.
225 Attempting a Normal mode IPL from 7012 DBA disk-attached devices specified in
NVRAM IPL Devices List.
226 Attempting a Normal mode IPL from Ethernet specified in NVRAM IPL Devices List.
227 Attempting a Normal mode IPL from Token-Ring specified in NVRAM IPL Devices List.
228 Attempting a Normal mode IPL from NVRAM expansion code.
229 Attempting a Normal mode IPL from NVRAM IPL Devices List; cannot IPL from any
of the listed devices, or there are no valid entries in the Devices List.
