- Move all the hardware initialization to EmulatorInitialize (since emulator.c can be viewed as support functions for emulating a PC motherboard) --> PS2 and VGA go there. - Break bios.c into bios.c and kbdbios.c (the keyboard bios module) (according to the IBM documentation as well as other emulator sources or SeaBIOS or...). - Move Exception handling from int32.c to emulator.c, because it's something tight to the emulator, not to the interrupt system by itself (yet it happens that INT 00h to 07h are commonly set to some exception handlers). In the bios.c, initialize those vectors with the default exception handler. - Handling IRQs is done fully in bios.c now: introduce PicSetIRQMask and EnableHwIRQ helper functions (adapted from their equivalents from SeaBIOS) that allows the bios to set (and activate in the PIC) a given IRQ with its corresponding handler. Also introduce PicIRQComplete that serves as a PIC IRQ completer (i.e. sends the EOI to the right PIC(s)). - Continuing on that, at the moment I set dumb default PIC IRQ handlers for IRQ 08h - 0Fh and IRQ 70h - 77h). - By default I disable all the IRQs; there are then set on-demand with EnableHwIRQ. - Rework the POST (aka. BiosInitialize function): * the memory size is now get from the CMOS (as well as the extended memory size via INT 12h, AH=88h), * then we initialize the interrupts, * then platform hardware (ie. the chips) are initialized, * and finally the keyboard and video bioses. - As said before, move memory sizes into the CMOS. - Simplify video bios initialization. svn path=/branches/ntvdm/; revision=61796
