    2525If you suspect IO interrupt configuration issues or PCI configuration issues,
    2626you can try using the /VW switch. When the /VW switch is used, the PSD does not
    27 alter the IO interrupt configuration and does not alter the PCI configuration
    28 from the way the BIOS has set it up. The APICs are enabled and multiple CPUs
     27alter the IO interrupt configuration from the way the BIOS has set it up. The APICs are enabled and multiple CPUs
    2928are enabled. This is known as Virtual Wire mode or APIC mode 1, or just Mode 1.
    3029ACPI and OEMHELP services are still available in Mode 1. 
     
    3635You can disable almost all of the configuration that the PSD does by using the
    3736/PIC switch. When the /PIC switch is used, the PSD doesn't touch any of the
    38 interrupt configuration, it doesn't touch any of the PCI configuration, and
    39 it doesn't touch any of the APICs. As a result, only 1 CPU will be initialized.
    40 This system configuration remains in the state that BIOS has setup. The only
    41 reason you would want to run a system with the /PIC switch is for testing
    42 purposes. This is known as PIC mode, or Mode 0. ACPI and OEMHELP services are
    43 still available in Mode 0.
