It does not cover the support needed from applications to enable the BIOS to update itself with the image downloaded in to the memory. In case of monolithic the driver allocates a contiguous chunk of physical pages having the BIOS image.
In case of packetized the app using the driver breaks the image in to packets of fixed sizes and the driver would place each packet in contiguous physical memory.
The driver also maintains a link list of packets for reading them back. The rbu driver needs to have an application as mentioned above which will inform the BIOS to enable the update in the next system reboot. The driver supports two types of update mechanism; monolithic and packetized. These update mechanism depends upon the BIOS currently running on the system.
Most of the Dell systems support a monolithic update where the BIOS image is copied to a single contiguous block of physical memory. In case of packet mechanism the single memory can be broken in smaller chunks of contiguous memory and the BIOS image is scattered in these packets.
By default the driver uses monolithic memory for the update type. This can also be changed later as below:. In packet update mode the packet size has to be given before any packets can be downloaded.Manually Updating the Firmwares on a Dell PowerEdge R610
