Overview
With the release of 0.2.7 we, the ReactOS Team, have once again gained
further compatibility with Microsoft Windows. We have aligned our
headers with those of the Windows SDK which gives us a greater range of
driver compatibility. We have also kept ourselves compliant with the
latest GCC compiler which with our new build system provides a faster
and more efficient building processing. We have elected a new UI
coordinator and work has begun to redo the interfaces seen by the user.
Many of our advancements aren't obvious to the end user, but rest
assured that the inner workings are coming together with work in USB,
Plug and Play, and networking that will blow you away in our next release.
Main 0.2.7 Changes
     * Header clean up to compatible Windows SDK headers. Implemented
and used NDK. ReactOS is now built with our own headers. Alex Ionescu,
Filip Navara, Steven Edwards
     * New My computer, Command Prompt, and Logo Icons. Mindflyer
     * New build system called rbuild. Based on xml, it allows for auto
generated makefiles. Casper Hornstup
     * Improved appearance of the first stage installer. Alex Ionescu
     * GCC 4.x.x build fixes. Thomas Weidenmueller, Alex Ionescu
Known Bugs
ReactOS will fail to boot with a AllocConsole error when a ps/2 mouse is
not attached on some hardware. Bug 688
(http://reactos.com/bugzilla/show_bug.cgi?id=688)
This ReactOS release requires 64MB RAM to complete the first stage
installer. Bug 703 (http://reactos.com/bugzilla/show_bug.cgi?id=703)

failure cases, set the right IRP flags and set the I/O Object Type.
           o Reimplemtented 2nd-stage completion for IRPs to free ALL
MDLs, free memory depending on the flags used, don't call I/O Completion

NtDeviceIoControlFile, NtLockFile, NtUnlockFile which contained several
bugs related to IRPs and completion, which were making assumptions or
not supporting all the possibilities, as well as signlaing the wrong
event or making the wrong kind of call, or using the wrong device object.
           o Implemented Lookaside lists for IRP packets to increase the
allocation/deallocation speed by over 400%.
           o Optimized Completion Packets by piggybacking them on IRP
packets if possible, and added the right memory flags to free them properly.

PsGetCurrentProcessSessionId, PsSetLegoNotifyRoutine,
PsRemoveCreateThreadNotifyroutine, PsGetVersion
           o Rewrote Process/Thread creation and exit functions.

           o Took out many system structures from NonPaged Pool to Paged
Pool to reduce physical memory consumption.

to BSOD the system.
           o Made the PE Loader more lenient so it can load some other
valid executables.

           o Fixed the lookaside functions, their macros and the way the
functions were being exported.

I think there is a bug in the FAT32.asm file of the boot loader. It
was fixed in the FAT.asm file but the fix wasn't applied to the FAT32
one yet.

Hi,
I think the bug has nothing to do with the fat boot code from freeldr.
If ReactOS stops after  'reactos setup' and two red lines, it is
somewhere between running setupldr and starting smss.exe (usetup.exe).
Possible ReactOS hangs while the initialisation of one of the boot load
drivers. If you are able to compile and build a bootcd, you can disable
line #346 in ntoskrnl\io\driver.c. After this you should see which
drivers are loaded.
