Command Information
Request Information
| Byte | Data Field |
|---|---|
| NetFn | 30h |
| CMD | 92h |
| 1:3 | Manufacturer ID, LS Byte first. The length is fixed to three bytes. For example, if the vendor ID is 2011 and the corresponding hexadecimal value is 0x0007DB, the first byte is DBh, the second byte is 07h, and the third byte is 00h. |
| 4 | Sub command, sub command=49h |
| 5:8 | Capability of obtaining the faulty address from the specified memory is reserved |
| 9 | Reading fault offset (reading the fault information offset, starting from 0, in the unit of the number of faults) |
| 10 | Reading the Number of Faults |
Response Information
| Byte | Data Field |
|---|---|
| 1 | Completion Code d6- indicates that the command is not registered on the BMC and the version is not matched. The BIOS SMI interrupt processing function automatically selects a BT channel to report fault information based on the returned value.If the value is obtained in the boot phase, the isolation function is not supported and the isolation operation is not performed. |
| 2:4 | Manufacturer ID, LS Byte first. The length is fixed to three bytes. For example, if the vendor ID is 2011 and the corresponding hexadecimal value is 0x0007DB, the first byte is DBh, the second byte is 07h, and the third byte is 00h. |
| 5 | End of List. indicates whether the data reading is complete, 0- Data reading is complete. 1- Data reading is not complete. |
| 6 | falut num: Returns the number of faults and the next read offset of the BIOS. The length of the IPMI command is limited. Therefore, falut num < = 5 |

| 11 | Memory 1 SubRank ID |
| 12 | Memory 1 Device ID |
| 13 | Memory 1 BankGroup ID |
| 14 | Memory 1 Bank ID |
| 15:18 | Row address of memory 1 |
