Rewrite the VGA emulation. Nah, it's a joke! - Store VGA registers setup in VGA_REGISTERS structure. - Improve BiosSetVideoMode and introduce a VgaSetRegisters function for setting VGA regs. - Initialize Bda->CrtBasePort: it is used to determine the address of some I/O ports which depend on whether we are in color or monochrome mode. - Add UnregisterIoPort in io.c (and fix some DPRINTs) (needed for VGA). - When setting the misc. VGA register, check whether we're going to monochrome emulation, and reset some port addresses in that case. svn path=/branches/ntvdm/; revision=61246
======================== ReactOS Version 0.3.x Updated Dec 16, 2006 ======================== 1. What is ReactOS? ReactOS is an Open Source effort to develop a quality operating system that is compatible with Windows NT applications and drivers. The ReactOS project, although currently focused on Windows XP/2003 drivers compatibility, is always keeping an eye toward compatibility with older version of Windows NT family ( NT 4.0, 2000 (NT 5.0)) and new Windows NT releases (Vista, etc). Applications (Win32 API) compatibility focus is Windows XP. More information is available at http://www.reactos.org/. 2. Building ReactOS See the INSTALL file for more details. 3. More information See the media\doc subdirectory for some sparse notes. 4. Who is responsible See the CREDITS file.
