Member Data Documentation

attribute boolean IBIOSSettings::logoFadeIn

Fade in flag for BIOS logo animation.

attribute boolean IBIOSSettings::logoFadeOut

Fade out flag for BIOS logo animation.

attribute unsigned long IBIOSSettings::logoDisplayTime

BIOS logo display time in milliseconds (0 = default).

attribute wstring IBIOSSettings::logoImagePath

Local file system path for external BIOS splash image.

Empty string means the default image is shown on boot.

Mode of the BIOS boot device menu.

attribute boolean IBIOSSettings::ACPIEnabled

ACPI support flag.

attribute boolean IBIOSSettings::IOAPICEnabled

IO APIC support flag.

If set, VirtualBox will provide an IO APIC and support IRQs above 15.

attribute long long IBIOSSettings::timeOffset

Offset in milliseconds from the host system time.

This allows for guests running with a different system date/time than the host. It is equivalent to setting the system date/time in the BIOS except it is not an absolute value but a relative one. Guest Additions time synchronization honors this offset.

attribute boolean IBIOSSettings::PXEDebugEnabled

PXE debug logging flag.

If set, VirtualBox will write extensive PXE trace information to the release log.

readonly attribute wstring IBIOSSettings::nonVolatileStorageFile

The location of the file storing the non-volatile memory content when the VM is powered off.

The file does not always exist.

This feature will be realized after VirtualBox v4.3.0.
