    SUSE reset methods


    When we write echo b > /proc/sysrq-trigger on suse terminal,
    Which of the following reset normally happens ,

    1)EFI
    2)BIOS
    3)PCI
    4)KBD
    5)ACPI
    6)SMP
    7)Triple fault
    CF9

    Is there any way to confirm the reboot source here? How can I verify it ?

    Please share your input on this!

    Tried trapping 0xCF9 , CF9 reset is not happening.

    Trying to trap 0x64 (KBD) thorugh debugger , couldn't find one

    I am sure EFI,BIOS,PCI not gonna cause reset.

    If it is reset via port 0x64 (writing 0xfe command to 8042 cause reset) ,how can I confirm ?
