I've been doing some looking at why winext2fsd doesn't work on reactos. This has been a pet project of mine for a while, but sadly I'm not very skilled in the parts of reactos that it touches. On the ext2 branch, I've got filips changes and some small changes of my own so that I can make a bootcd that will try to install reactos on a fresh ext2 partition. ext2 starts writing the first file to the empty filesystem but stalls when a call to WriteCacheSegment causes ext2 to do a paging write of several pages to class2, which uses ScsiClassSplitRequests to send several blocks to scsiport for writing. The interesting thing is, in the case where my diff prints DEADLY WAIT, SpiProcessRequests receives the IRPs but does not enter the while loop that would process them, nor receive any further completions. At this point i'm totally stuck and so I'll try to isolate the relevant debug output. If somebody is interested and has some spare time I'd appreciate a bit of wisdom about how the DeviceExtension->Flags, NextIrp, ActiveIrpCount and PendingIrpCount fit together. I think that if the IRPs are completed then the rest will work, since the split IRP code in class2 seems reasonable. http://64.81.145.152/~arty/ext2.diff <-- Lots of annotation http://64.81.145.152/~arty/ext2.log <-- Last part of execution http://64.81.145.152/~arty/rosbin.zip <-- Binaries from my tree In the log it is writing atapi.sys to \ReactOS\system32\drivers on the disk. DEADLY WAIT(0) is the place where ext2 can't progress from. It's at line 200 or so in drivers/fs/ext2/src/io.c. The fatal invocation of SpiProcessRequest looks like this before the while loop: (scsiport.c:2864) DeviceExtension->Flags & IRP_FLAG_COMPLETE 0 (scsiport.c:2866) DeviceExtension->SrbExtensionSize 0 (scsiport.c:2869) DeviceExtension->CurrentSrbExtensions 0 Max 0 (scsiport.c:2871) DeviceExtension->PendingIrpCount 4 (scsiport.c:2873) DeviceExtension->Flags & (N|NLU) 0 (scsiport.c:2875) DeviceExtension->NextIrp c0457db0 The wierd thing is that it seems that atapi relies on the ide controller raising an interrupt after IDEWriteBlock, which never happens for me under qemu after this point. This is where I get totally lost unfortunately. I'll try to learn more as I go but any help understanding scsiport is appreciated. Art -- Here's a simple experiment.

None the less, you may soon begin to notice that something important is happening. -- Robert Stirniman

RE: [Spam] [ros-diffs] [royce] 13154: require attributes to have values

by Casper Hornstrup

The magic number 1 may be obvious to some, but it isn't to all. It should be true/false, yes/no or all of the above.

Hey guys...

by Richard Campbell

I'm re setting up my ROS dev environment, after a format/reinstall, and i'm encountering the following problem under both QEMU and ReactOS: While booting from the livecd or the bootcd i get an inaccessible boot device error. The HD partition on VMWare is a FAT32 partition formatted in win98, the partition in QEMU is an unformatted partition. Any idea on how to fix this?

binutils-2.15.90

by Ge van Geldorp

Since binutils-2.15.90 (which you need to build a bootable ReactOS) is no longer available from the MinGW download pages, I put it on the ReactOS download page on SourceForge: http://sourceforge.net/project/showfiles.php?group_id=6553 Gé van Geldorp.

Zw/Nt functions

by Hartmut Birr

Hi, currently our Zw functions for kernel mode are implemented by an parameter wrapper and an int 0x2e instruction. The only reason for using the Zw functions in kernel mode is to bypass the buffer check. Can we implement the Zw functions by saving/changing/restoring the previous mode and calling the equal Nt function? - Hartmut

comdlg32 wierdness..

by Richard Campbell

Currently the resource files in comdlg contain a listbox entry similar to below: LISTBOX IDC_SHELLSTATIC,4,20,272,85, LBS_SORT | LBS_NOINTEGRALHEIGHT | LBS_MULTICOLUMN | WS_HSCROLL | NOT WS_VISIBLE shouldn't it be LISTBOX IDC_SHELLSTATIC,4,20,272,85, LBS_SORT | LBS_NOINTEGRALHEIGHT | LBS_MULTICOLUMN | WS_HSCROLL the NOT WS_VISIBLE causes windres errors (windres doesn't recognize NOT, and even if it did, saying NOT WS_VISIBLE instead of just not | WS_VISIBLE is redundant.), which causes the DLL to fail to build. While this appears to be merely a goofup, figured i'd ask about it in the list before i make any changes to the tree in case this is there for a reason. Richard

Do you know however if any of ROS Kernel depends on the old GDT? There are two weird issues with SYSEXIT: 1) GvG reported that FPU is broken 2) Explorer now crashes in shlwapi when clicking on a disk. Best regards, Alex Ionescu
