[NTVDM][FAST486] - Implement VDDInstallMemoryHook and VDDDeInstallMemoryHook using page guards. - Implement another API for memory hooks that should be faster than page guards (for NTVDM only). - Adjust the VGA and EMS memory handlers to use this method. - In Fast486, implement a method that will allow us to "rewind" the current instruction, in case it was interrupted by a memory hook page fault. - Use a memory hook to protect the BIOS ROM from being written to. svn path=/trunk/; revision=66666

[NTVDM]: Commit what I have in my local wc so far (and which is commitable & works): - Simplify PicIRQComplete helper function. - Set up temporary stack for the BIOS. - Initialize the "User Data Area" that is found at 0050:xxxx (see http://helppc.netcore2k.net/table/memory-map for more details). - Some INT --> UINT - Simplify few macros. - Simplify DOS initialization; add few functions that will be useful later on. - Remove trailing whitespace. svn path=/trunk/; revision=68159

[NTVDM] - Move the VDD memory handler API prototypes to the corresponding DDK header. - Fix few function arguments types and add few more comments :) - Move all NTVDM-memory related functions to memory.c - Prefer checking for !IsListEmpty(&list) instead of doing list.Flink != &list (ehh! NTVDM is not win32k!!) svn path=/trunk/; revision=66669
