#6837 fixed EFI bios failt to detect HDD's attached to the SATA -> fixed in SVN Alexey Loukianov
Description

When the virtual machine is set to use EFI it is impossible to boot from any disk attached to the emulated SATA controller.

To reproduce: Create a new VM, set it to use EFI, delete all disk controllers. Then add one SATA AHCI controller and attach any HDD to it (say, to the SATA port 0). Try to power on the machine and it will get into EFI shell after some time. Use "map" command to display current device mappings and notice that there are no maps defined. Use "devices" command and notice that there are no block disk devices found.

Power off the vm, delete SATA controller, add standard IDE instead and attach an HDD to it. Try to boot up the VM, get into EFI shell, issue "map" and notice that there are block devices maps found. Issue "devices" and notice that the IDE controller and HDD were detected.

Confirmed to happen on Virtual Box 3.2.0 on CentOS 5 32bit PAE (RHEL5) host and on Fedora 9 32bit PAE host.

#11707 obsolete IGuestProcess.Read and IDisplay.TakeScreenShotPNGToArray throw exception LeeEll
Description

I am using the VirtualBox 4.2.12 COM API with C# NET 4.0 and Visual Studio 2010, host OS either Win7-x64 or WinXP-x86, guest OS WinXP-x86.

API functions IGuestProcess.Read and IDisplay.TakeScreenShotPNGToArray have System.Array as return type signature. This return type compiles but causes the following SafeArrayTypeMismatchException marshaling exception at runtime:

Specified array was not of the expected type.

at System.StubHelpers.MngdSafeArrayMarshaler.ConvertSpaceToManaged(IntPtr pMarshalState, Object& pManagedHome, IntPtr pNativeHome)

at VirtualBox.IGuestProcess.Read(UInt32 aHandle, UInt32 aToRead, UInt32 aTimeoutMS)

Calls that cause this exception are:

System.Array output = GuestProcess.Read(0, 2000, 5000);

and

Console.Display.TakeScreenShotPNGToArray(0, 640, 480);

I have tried var as return type. That compiles but throws the same exception. I have also tried byte[] and a lot of other array types and a cast to System.Array to make it compile, but still get the same exception at runtime.

It looks as if the API is seriously broken for functions that have array return types.
