Method Detail

reset

public boolean reset()

Reset all parameters of module.

Specified by:

reset in interface Module

Specified by:

reset in class AbstractModule

Returns:

true iff the AbstractModule was reset properly.

getDump

public java.lang.String getDump()

Return a dump of module status

Provides a dummy implementation since many of the subclasses of this abstract module class do not need or use a getDump() implementation. The ones that do, can override this method.

Specified by:

getDump in interface Module

Overrides:

getDump in class AbstractModule

Returns:

string containing a dump of this module

getSystemBIOS

public byte[] getSystemBIOS()

Returns the system BIOS code from ROM

Specified by:

getSystemBIOS in class ModuleBIOS

Returns:

byte[] biosCode containing the binary code of System BIOS

setSystemBIOS

public boolean setSystemBIOS(byte[] biosCode)
                      throws ModuleException

Sets the system BIOS code in ROM

Specified by:

setSystemBIOS in class ModuleBIOS

Returns:

true if BIOS code is of specified SYSTEMBIOS_ROM_SIZE and store is successful, false otherwise

Throws:

ModuleException

getVideoBIOS

public byte[] getVideoBIOS()

Returns the Video BIOS code from ROM

Specified by:
