If Boot Loader Image Is Less Than 8 Mb; Booting The Example Boot Loader; Figure 9. Power (Top) And Reset Buttons - Intel Cougar Canyon 2 Platform Manual

6.4.1
If your boot loader image is less than 8 MB (such as 4 MB or 1 MB), the boot loader
image be programmed to the end of the SPI-1 chip. For example, a 4 MB image must
be programmed to the last 4 MB of the 8 MB chip, and a 1 MB image must be
programmed to the last MB of the 8 MB chip.
Follow the exact procedure in Section
Instead of step 11, select Program from specific address of a chip, and enter the
appropriate starting address to match your firmware image. For example, if your
firmware image is 4 MB in size, specify a starting address of 0X0400000. If your
firmware image is 1 MB in size, specify a starting address of 0x0700000.

Booting the Example Boot Loader

By default, the Coreboot-based example boot loader boots into the Coreboot-provided
SeaBIOS. The default behavior of SeaBIOS is to seek a bootable OS image on an
attached storage device, such as a SATA or USB disk.
To interact with the boot loader, connect a terminal or terminal emulator to the DB-9
serial port. The CRB provides Power and Reset buttons, as shown in
power up the board, turn on the power supply, and then press the board's Power
button.

Figure 9. Power (Top) and Reset Buttons

When power is applied to the CRB and the boot loader initializes the board and boots
the SeaBIOS payload, various messages appear on the terminal connected to the
serial port.
