Author: ion Date: Tue Jan 5 06:09:22 2016 New Revision: 70492 URL: http://svn.reactos.org/svn/reactos?rev=70492&view=rev Log: [BOOTLIB]: Separate out bcd.c into bcdopt.c, bootreg.c and bcd.c [BOOTLIB]: Implement routines to enumerate subkeys and to read a key value. [BOOTLIB]: Implement routines to parse, enumerate, and convert registry data into BCD elements, and to convert BCD elements into boot library BCD options. [BOOTLIB/BOOTMGFW]: Lots of cleanups, mainly around the fact we now use ntintsafe.h instead of the manually self-inlined code from before, and from documenting additional flag values, and from using our newfound BCD powers. [BOOTMGFW]: Implement BmGetOptionList, BmpUpdateApplicationOptions. [BOOTMGFW]: Prepare for post-BCD library reinitialization. We correctly read the 3 BCD options so far in the hive.

Author: gedmurphy Date: Mon Jan 4 12:50:06 2016 New Revision: 70488 URL: http://svn.reactos.org/svn/reactos?rev=70488&view=rev Log: [FLTMGR] - Plug in the dispatch routines. These are just pass through methods for now to get the filter up and running. - Implement the FastIo handlers. The majority of these call the FastIo routines of the attached device object. - Make sure we detach from devices that are being deleted in FastIoDetachDevice. - Move the FastIoDetachDevice routine to a deferred call as it's too expensive to tie up a FastIo request.
