At the end, Windows 2000 Professional inside Qemu Virtual Machine works. I needed half a day but now I've finished the installation of Windows 2000, .NET SDK 2.0 Beta 2 and Visual C# 2005 Express Edition Beta. I needed all of these things because I need to test DataGridView for the MONO implementation. Today I'll start to take notes of the work with the control I'm implementing and tomorrow I'll start to exec that control in MONO with the mimimum implementation to get an impresssion of what methods/properties/events should I implement first.
