HDD Geometry switch

by caemyr＠myopera.com

Is the new geometry backward-compatible? If i recreate the partitions, will they be visible when i regress test revisions before 54511? -- With best regards Caemyr

Rbuild debug & KVM tester offline

by Pierre Schweitzer

Hi, due to connectivity issues with our servers in Sweden, I've taken our rbuild debug buildslave & our KVM testbot offline. This doesn't affect ISOs storage for the moment. Regards, Pierre

I see this and I LMFAO! co_IntSendMessageNoWait(Window->head.h, WM_WINDOWPOSCHANGING, 0, (LPARAM) WinPos); co_IntSendMessageNoWait(WinPos.hwnd, WM_WINDOWPOSCHANGED, 0, (LPARAM) &WinPos); There is more too! Amazing! Please tell me this is not wrong!!!! James

Re: [ros-dev] New harddisk geometry

by Love Nystrom

Hi People, I'm back after my ordeal in Europe and finally got an inet line.. But now I've over 300 mails from the list to wade through.. Ugh. It's gonna take some time to get up to speed. Hi Eric, That's all fine, it's just an educated choice of disk parameters as I see it. But anyway, all disk handling software (drivers etc) should honor whatever disk parameters you write in the boot record when you format the partition, and whatever geometry you write in the MBR when the disk gets partitioned, whether it's this or that. Just in case someone forgot ;) Best Regards Love > From: Eric Kohl <eric.kohl(a)t-online.de> > To: ReactOS Development List <ros-dev(a)reactos.org> > Date: Mon, 21 Nov 2011 23:17:40 +0100 > Subject: [ros-dev] Announcement: New harddisk geometry next weekend > Hi! > > I plan to change the standard harddisk geometry from the old 32 sectors and 64 heads geometry to the > new 63 sectors and 255 heads geometry next weekend.

The old code was "&LunExtension->MiniportLunExtension", which seems to make more sense.

Re: [ros-dev] [ros-diffs] [jgardou] 54462: [RTL] - explicitly truncate some values, so it doesn't count as an error for compiler/MSVC runtime checker

by Timo Kreuzer

That doesn't make much sense. Whats the point of the LOWORD() macro, if not truncating it ? Fix the macro if its broken.

Announcement: New harddisk geometry next weekend

by Eric Kohl

Hi! I plan to change the standard harddisk geometry from the old 32 sectors and 64 heads geometry to the new 63 sectors and 255 heads geometry next weekend. The old disk geometry was used up to Windows NT4 and the new geometry is used since Windows 2000. So I guess it is time for ReactOS to make this change too. ;-) This should improve the compatiibility with other OSs because every modern OS uses the new disk geometry. Please note that you must delete and re-create all partitions on your virtual harddisk in order to get a clean partition table when the new disk geomerty is in use. Regards, Eric

Re: [ros-dev] [ros-diffs] [cgutman] 54418: [HALX86] - Do not allow software interrupts to preempt code running with interrupts disabled during KfLowerIrql

by Aleksey Bragin

I would like to ask our kernel gurus if this one is correct. WBR, Aleksey Bragin.
