leave the exceptions to be implemented under model/.
More precisely we provide a well documented version of early_serial.c

to implement `non-standard` initialisation code should such a (unlikely)

Except for tyan, (MAX_CPUS * MAX_PHYSICAL_CPUS) % 256 == 0.
Together with documented 4-bit restriction for APIC ID field, this APIC ID

Intercept the low battery SMI from the EC, and shut down the system

On the other hand, payloads such as GRUB or SeaBIOS will experience
the shutdown. This behavior is helpful for protecting the battery, for
example, when the OS fails to boot and we are stuck in the payload.
The low battery SMI is triggered at 10% charge, at which point the risk

The EC may disable some functionality, such as Caps Lock LED and
battery charging if it never receives a command to go in APM mode. If
we start it in APM mode, then immediately switch to ACPI mode, it will
not get its SCIs serviced until an ACPI OS boots. If its SCIs are not
serviced, it may assume the OS has hung.
The way we solve this is to initalize the EC in APM mode, and only
switch it to ACPI when an ACPI-capable OS issues the ACPI_ENABLE
command. The switch has to be handled in SMM.
Although we aren't yet processing SMIs from the EC, we are reading the
status in order to satisfy the EC that the event is handled.
