No previous reset N/A 0x00

Power-on reset cold 0x01

CFD Watchdog cold 0x02

BMC Watchdog (cold reset) cold 0x03

FRU Control (cold reset) cold 0x06

Legacy FPGA cold reset cold 0x09

From Emulator to request a cold reset cold 0x0A

ICH upon request for cold reset cold 0x04

BMC Watchdog (warm reset) warm

0x81

FRU Control (warm reset)

This reset source is not supported in CPM IPMI firmware v1.06 and above.

warm

On the CPM, all warm reset sources are converted by the legacy FPGA to cause a cold reset.

For example, a reset pushbutton assertion causes a warm reset and the legacy FPGA converts

it to a cold reset.
