Re: [ros-dev] Freeldr problems resolved
by Sylvain Petreolle 10 Apr '05

A simpler fix would be to a change of the BootDrive value to 0xFF. As you said, the current value is 0, but thats by design, since all the values have been filled for a 1.44M diskette. Even the File System ID could have been set differently, since the neutral value 'FAT ' is allowed here. --- Phillip Susi <psusi(a)cfl.rr.com> wrote: > Well, I finally solved my problems with getting freeldr to boot from a > hard drive.

I had the same problem on real hardware. I removed serenum & serial.sys and the system could boot again. I dont know if the problem is into serenum or serial though. hpoussin, it seems the solution is in your hands ;) --- Saveliy Tretiakov <saveliyt(a)mail.ru> wrote: > revision 14561 can't boot on vmware 4.5 > debug output is attached > > _______________________________________________ > Ros-dev mailing list > Ros-dev(a)reactos.com > http://reactos.com:8080/mailman/listinfo/ros-dev Kind regards, Usurp (aka Sylvain Petreolle) humans are like computers, yesterday the BIOS was all - today its just a word

Fix numlock state at ros startup
by Sylvain Petreolle 09 Apr '05

09 Apr '05

Some bioses set numlock to on at startup. Since ReactOS is setting it to off state, the LED status must be set accordingly. Attached patch fixes it. Kind regards, Usurp (aka Sylvain Petreolle) humans are like computers, yesterday the BIOS was all - today its just a word

Short leave of absence
by Alex Ionescu 09 Apr '05

09 Apr '05

Hi, I am currently entering the last 5 weeks of school of my last year, so I'm going to be focusing on that instead of ReactOS. Lately, I've tried to work on both, but this has delayed my code as well as hurt my grades. I intend to be back around the week of May 10th. In the meanwhile, I would kindly like to ask developers to e-mail me if they have any plans to touch the following: - Kernel Scheduler, Thread Creation, Context Switching, System Initialization. I have re-written everything for a faster and more complete system based on NT semantics. Includes everything from realtime support, proper dynamic and static priorities, real system thread support, much faster scheduling, pre-emption, removal of the PEB/TEB 64K block hack and ros-only members, better organized code and Mm routines for manipulating kernel stack/teb/peb, etc... - Pushlocks. I have almost all the necessary support code written and I'm only missing one function. - IRQL management in HAL and Spinlocks. I have highly modified the IRQL routines for a large increase in speed, as well as made spinlocks faster on UP and non-debug builds. I have also corrected some IRQL routines to use the proper KPCR members for the IRR and others. - Object Manager. I have a complete re-write in progress which uses public NT structures instead of our internal ones, adds more security, and corrects some missing features and adds some. Majorly changes some aspects of the Ob (for example regarding on the status of handle/pointer count after creating an object, and the work of ObCreate/ObInsertObject, which is totally different in ROS vs NT. See blog article for more info). However, any bugs that are easy to fix should still be fixed in the current Ob. The new one is months away. - Queued Spin Locks, KGATES, Guarded Mutex. I already know Filip is working on this and I was planning on collaborating with him. Unlike the previous things, I haven't actually *coded* anything regarding these, but I have the design in my head and would like to work on it, so I would love to share what I know if anyone is actively interested in working on it. Once again, to clear up any misconceptions, I'm asking an email to know if anyone plans to work on this for the purposes of: 1) Not duplicating work 2) Sharing what information/code I might have written. In any case, I'll be back in exactly one month, so I don't think it'll matter. You guys keep focusing on PnP and other stuff meanwhile, okay? *joke* Best regards, Alex Ionescu

Hi, it'd be nice if something like r14554: Delete riched20 r14555: Copy riched20 can be avoided in preference of the *cause* the required the changes above. Everybody can see that riched20 was deleted and added afterwards but you cannot see *why* this has been done. Regards, Mark
