Which are current installation methods for ReactOS? so far only an ISO it seems, which for non-emulators requires to write/burn a disk, turn it into a drive that can read burned media (not all cdrom drives can do this), and also requires El-Torito support from the system BIOS. That last part might be worked around, if not supported by the system, by using Smart Boot Manager, which provides its own Eltorito stack. Questions: -why do an installed ROS, a ROS LiveCD and a ROS installCD all have a directory (root_of_drive)\REACTOS ? This makes it complex to have all 3 on 1 drive. WindowsXP/BartPE can use C:\WINDOWS (installed), C:\I386 (setup) , C:\MINIPE (LiveCD) for example -Is it possible to copy the contents of the install CD to a 2nd fat partition, and setup FreeLDR (on diskette for example) to boot that directory? some line like: multi(0)disk(0)rdisk(0)\partition(2)\ReactOS="Install ReactOS from D:\REACTOS to C:\REACTOS" if the ReactOS install CD used any other directory name than a hardcoded '\REACTOS', then 1 partition would have been enough. multi(0)disk(0)rdisk(0)\partition(1)\ROSsetup="Install ReactOS from C:\ROSSETUP to C:\REACTOS" -How do I obtain FreeLDR, other than "installing ReactOS in an emulator first and selecting to install bootloader to A:" ? Can't find the old DOS INSTALL.COM/EXE file along with both FREELDR.SYS/INI -Does installing ReactOS from harddisk actually work? At least it prevents users having to provide controller/cdrom drivers (be it DOS or Win32 drivers). -Anyone tried ROS LiveCD + QEMU (without configuring a harddisk!) ? doesn't bootup, might be a QEMU issue. Vmware + LiveCD works, though C was assigned which isn't nice in case you decide to partition in a GUI Diskmanagement subsystem. In best case, FreeLDR or a minisetup would be able to handle a (zipped) ISO by extracting the files inside it to a temporary location, and start setup from there. Is there any premade FreeLDR diskette image available somewhere? Bernd

It is replacing clear and easily debuggable code by non-standard macros which are impossible to debug. It is also going to create problems when people which are not used to them (such as myself): 1) Have no idea what some LIST_FOR_EACH_SAFE thing is doing vs LIST_FOR_EACH vs InsertListLifoSafeMaybeLoopOrWhoKnowsWhat 2) Will never code using these macros, and thus the source will become full of both methods, which is totally ugly. Sometimes, especially in kernel code, it's much better to have an expanded logic then to use a macro. I wrote a great majority of the code that has just been, imho, pollutted with these macros, and I don't appreciate for someone to barge in and change my code for some macro that I don't understand, nor wish to, because it only causes problems. I take great care of the code I write and "own" it (in the programming term) so that if a bug in it arises, I can quickly identify it and be held responsible for it. The addition of these macros hinders that effort. I don't mind someone using them inside his or her own code. I just mind their usage in ntoskrnl, and even more so when it overwrites the clean, clear code that I've written and am used to debugging. Best regards, Alex Ionescu

software purchase for web forums

by Steven Edwards

Hello, The web teams has requested that we purchase a software package to handle our forum discussion on the website. The purchase cost is $160 http://www.vbulletin.com/ We have about $90 in paypal donated for misc needs and this seems like a good buy if we really need it. After our hack of the website this may be a good thing. I would like to have a vote up or down about the purchase. If the majority of the project supports this then once we reach the required amount we will purchase. Please reply to me in private, the foundation or general lists only. Do not follow this thread on ros-dev. Thanks Steven __________________________________ Yahoo! Mail - PC Magazine Editors' Choice 2005 http://mail.yahoo.com

Subsystems, how to write one

by crashfourit

What are the relevent ReactOS API calls for building a dynamicly loadable subsystem? I'm asking this because I can't find the API documentation on the website. (I looks more like the documentation is not yet completed.) Other questions relevent to this: How do I register a new executible file format? I.E. coff. How do I register a new interrupt vector(s). What are the API to control v86 prosses? If y'all want to know what subsystem I want to write, it is DOS. This is because I'm more familar with programing in DOS.

New website

by Ge van Geldorp

Thursday afternoon (UTC) the website will be unavailable for some time. We're going to make the switch to the new website design then. At the same time, we're moving to www.reactos.org as the primary name for the website, with www.reactos.com being an alias (you'll be redirected automatically to www.reactos.org if you use the old name). The mailing lists are also going to be moved from reactos.com to reactos.org, so if you have filtering in place please take this into account. Many thanks to Michael Wirth and especially Klemens Friedl who put a lot of effort in the new site. Gé van Geldorp.

You use a macro to hide a 'for' loop, and later in the source you use a 'break', 'continue' or 'goto' statement to leave the loop or to bypass some code. /* Find entry with SortKey greater than or equal to the passed-in SortKey */ LIST_FOR_EACH(ReturnEntry, &DeviceQueue->DeviceListHead, KDEVICE_QUEUE_ENTRY, DeviceListEntry) { /* Check if keys match */ if (ReturnEntry->SortKey >= SortKey) { /* We found it, so just remove it */ RemoveEntryList(&ReturnEntry->DeviceListEntry); break; } } Such a source is simply unreadable. - Hartmut

I'm not able to install reactos on real hardware. Reactos hangs within CmInitHives at the first boot after the second stage setup. The same boot cd works in qemu. - Hartmut

Re: [ros-diffs] [ion] 18082: - Fix a bug in CSR Capture APIs

by Thomas Weidenmueller

ion(a)svn.reactos.com wrote: > + CsrCaptureMessageBuffer(CaptureBuffer, > + NULL, > + Size, > + (PVOID*)&Request.Data.PeekConsoleInputRequest.InputRecord); The last parameter passed to CsrCaptureMessageBuffer in your changes looks horribly wrong. The typecast hides the bug and shouldn't be necessary, the compiler would've warned you that this is most likely wrong. - Thomas
