4.1.3 Interrupt Routing
The BIOS provides the interrupt routing to the operating system through the following
interfaces:
 PCI IRQ Routing Table (non-ACPI environment)
 Multi Processor Table (non-ACPI environment)
 ACPI_PRT packages (ACPI environment)
 ACPI Multiple APIC Description Table (ACPI environment)
4.1.4 PCI Initialization
The BIOS supports PCI BIOS Specification Revision 2.1.
During power-up self test (POST), the BIOS identifies all PCI-to-PCI bridges and all PCI devices
with a header Type 1 in the system. It then initializes them according to their resource
requirements.
If the PCI’s option ROM is detected, it will be executed and its function implemented. The
network option ROM adds new boot option to the BIOS boot table. The SAS option ROM shows
SAS configuration utility menu which lets the end user create RAID volume.
4.1.5 I/O Device Configuration
4.1.5.1 Serial Ports
The ATCA-7370 supports two serial ports in OS, but supports only one serial port for console
redirection in BIOS. The default value is 3F8h/IRQ4.
4.1.5.2 Integrated SATA Controller
The BIOS provides setup items to configure the embedded serial ATA controller for debugging
purposes. Hard disk autotyping is also supported. The BIOS automatically determines the
proper geometry for hard disks by reading the information from the drive.
