ACPI.PSD

ACPI PSD PSD=ACPI.PSD

Parameters
(Arca Noae)
 * /NOACPI : Prevents the PSD from enabling some ACPI services. This switch is experimental.

Bus - make the bus %name% with %bus number% work in APIC mode else it remains in PIC mode. In other words, inform all devices on bus %name%, that they are working in APIC mode. If using ACPI snooper then /B is not needed. Output - The number of COM ports used for debug output (values: 1, 2, address of I/O port) It is suitable for debug version of acpi.psd. Configure receiver: 115200,8,n HW flow control Example: /CST:XCST. You can find the method in the subtree of CPU. (It's Cx state). It is needed for APM, idle of CPU
 * /SMP - activate multi-processor support
 * /B:name:number
 * /Onumber
 * /LS:number - Leave Sleep - after sleep state the computer will be switched to this state (0 - no switch, 5 - turn off)
 * /PIC, /APIC - Multiprocessor support can run in 2 modes: PIC or APIC. PIC is default, Use /PIC to activate 8259 PIC instead of APIC.
 * PIC is good enough
 * APIC is better but doesn't work on some computers and requires extra efforts to setup computer.
 * /CST:name - name of method responsible for _CST method.
 * /AFS - By default ACPI is started from ACPI.PSD. Use this switch to start ACPI from snooper. Use it if using ACPI snooper. Usually you need this if loading ACPI table via snooper. This switch has no effect if using SMP.
 * /IRQ:x - Experimental switch (specially for Acer Ferrari notebook) Allows replace ACPI IRQ number
 * /NOD - (Enabled by default) Experimental switch to activate internal OEMHLP$ driver disable acpica.add if using this switch. APIC mode may work bad without this switch.
 * /!NOD - Disable internal OEMHLP$ driver. Don't forget activate acpica.add (read troubleshooting.doc)
 * /R - Use ACPI Reset instead of kernel's reset. It is useful if running SMP kernel only. Use it if have troubles with system reboot or shutdown.
 * /FS - "Full Safe" - use this key for Dell notebooks
 * /EIS - "Enable Intel Slack", AcpiGbl_EnableInterpreterSlack - The Intel interpreter strictly follows the ACPI specification. Setting this switch allows the interpreter to ignore certain errors and/or bad AML constructs. Use it if ACPI log contains errors messages.

This switches are useful for APIC mode only: 0x??? (hex) 0??  (octal) ???  (decimal)
 * /CD - "Crazy Device" - use this switch if USB doesn't work
 * /TMR - Use it if running SMP machine and the motherboard doesn't follow MPS 1.4 standard.
 * /DV:vector - Dummy Vector - hide the vector. The kernel will not process it. (/DV:0x57 is enabled by default on every PC now)
 * /Q - Quiet mode. It does not show any message on normal boot.
 * Note:All digital values are accepted in hex or decimal form:
