Abstract: Changing accelerator card images without rebooting a host system includes receiving, within an integrated circuit (IC) of an accelerator card, an address of a platform image stored in a non-volatile memory of the accelerator card. The address is received over a communication link between the host system and the accelerator card while the communication link is connected. Changing accelerator card images includes detecting, within a register of the IC, that a warm boot enable flag is set and that the communication link with the host system is disconnected. In response to detecting that the warm boot enable flag is set and that the communication link is disconnected, loading of the platform image from the address of the non-volatile memory into the integrated circuit is initiated.
