PS2: - By default all the PS/2 ports are disabled. They become enabled by the BIOS at the POST step. - Similarly it is the BIOS POST that sets up the PS/2 controller configuration byte. - Synchronize the value of bit 2 "System flag" and bit 4 "Keyboard enable flag" in the status register, according to what is set in the controller configuration register. What is the "keyboard enable flag" ? See http://www.os2museum.com/wp/the-dos-4-0-shell-mouse-mystery/ for more details... HW MOUSE: - Resetting the mouse sends also an ACKnowledge byte too... BIOS32: - Fix the reported number of bytes in the BIOS configuration table. - Enable the PS/2 ports in the POST. - Implement the "Pointing Device BIOS Interface" INT 15h, AH=C2h, AL=00h...09h based on VBox OSE & SeaBIOS; we should make our PS/2 mouse driver use it. The real call to INT 15h, AH=C2h function is still disabled because our mouse driver doesn't react well with it, when we run some applications like MS Diagnostics. PS2 MOUSE DRV: - Update copyright notice; - Remove 2 useless functions; - I've put in comments in the code the places where calls to the BIOS ps/2 mouse interface are needed. svn path=/trunk/; revision=68613
