/* FUNCTIONS ******************************************************************/
VOID PicInterruptRequest(BYTE Number);
[FAST486] Separate external interrupts from interrupt signals (which are interrupts whose number is not known until they can be serviced, just like hardware interrupts on a real CPU). [NTVDM] Improve the PIC emulation code (IRQ priorities, etc...). Instead of checking for interrupts in the main loop, move the PS/2 input parsing to a different thread. Improve BIOS keyboard IRQ handling. svn path=/branches/ntvdm/; revision=60761

[DDK:NT_VDD] Declare some VDM memory services. [NTVDM] - Almost all of the XXXInitialize functions just return TRUE always, so VOIDify them instead (since they always succeed). - Move almost all of the hardware initialization inside EmulatorInitialize. - Move pure console initialization/mode-saving/cleanup code into ConsoleInit/Cleanup functions in ntvdm.c instead of in bios.c. svn path=/branches/ntvdm/; revision=61588
