4.1.6 Boot Options
The ATCA-7370 supports BIOS Boot Specification 1.01. The BIOS identifies all IPL (BAID, BEV)
devices and BCV devices (hard drives, USB sticks) in the system and will attempt to boot them
in the order specified in startup.
The following boot devices are integrated in the BIOS:
 USB devices (sticks, hard drives, CD-ROM)
 Network (BEV)
 SAS HDD connected to C604 chipset
 SATA connected to C604 chipset
 EFI Shell
The default boot order is as follows:
 Attached USB CD-ROM
 Attached USB devices on the external USB port
 SAS HDD
 SATA HDD
 Base Ethernet Interfaces
If BIOS does not find any ready bootable device, it will loop on the source list until a boot device
becomes ready. After 10 loops the BIOS initiates a cold reset and retries again or when
configured the BMC watchdog bites.
BIOS organizes the devices in groups: CD-ROM, HDD, network, floppy, SAS HDD. Any device
can be set as the first boot device by raising it to the first boot device of its device group, then
raising that group to the first boot group.
The boot order for a certain device and its device group can be set even in the absence of that
device. The order is preserved. When the device is added later, it will be available at the
specified boot order.
4.1.6.1 Boot Support for the SAS Controller
The BIOS contains an option ROM SAS controller on the payload. Legacy boot from SAS HDDs
is supported.
