Any semi-experienced assembly programmer would also tell you that CMOV is only available on P6 architecture or later (and support should be checked with CPUID in any case).

Topic: Parts needed for filesystems. Not fight over filesystems.

FAT is simple enough, but NTFS is undocumented and proprietary, whereas filesystems commonly used with Linux are well-documented and open. There is a need for a filesystem other than FAT that no current NTFS driver can fill, and it would be simpler and faster to use one of the well-tested, well-docu...

Concentrating on attributes supported by a FAT filesystem (read-only, system, hidden, archive), this is relatively simple - archive, hidden, and system could be stuffed into some bits not used by the FAT-style attribs, like the SUID, SGID, and sticky bits (this wouldn't be very polite if you wanted ...

Looks very cool! Would it be possible to add a setting to make the titlebar gradient go the right way so you can actually read the title? :)

I would guess you could chainload FreeLoader from lilo with something like the following (though I haven't tested it), assuming FreeLoader is installed in /dev/hda1:

Code: Select all

other = /dev/hda1
label = ReactOS
I think the ReactOS installer has an option to install to a particular partition instead of the MBR.

The Welcome screen is okay for casual home users, I guess, but it is worse than useless in a business environment - you can't log onto a domain, and you lose the protection of the Ctrl-Alt-Delete sequence.

That is the shutdown dialog when you have the Welcome screen enabled. When you disable the Welcome screen (the way it should be :) ), you get the classic shutdown dialog with a combo box:

I installed Beta 2 today at work on a Pentium 4 (don't know the clock speed off-hand) with 256 MB of RAM and some kind of integrated Intel Extreme Graphics. It failed to install when I booted from the DVD (! why is it so big to need a DVD?!), but installing from an already-running Windows XP went sm...

If asm section is correct it should look like xchg [ebp-0x4],[ebp-0x8] correct you should save one clock cycle to what you were doing. xchg still might be slower due to processors handling of memory blocks. mov eax,[ebp-0x4] mov [ebp-0x4],[ebp-0x8] mov [ebp-0x8],eax No x86 instruction can take two ...

Something like

Code: Select all

#define xchg(a, b) __asm__ ( "xchg %0, %1" : "=r" (a), "=r" (b) : "0" (a), "1" (b) )
would probably be better, since that will let gcc have more flexibility in using values already in regs and such.

AFAIK, the only way USB input is currently supported is through BIOS "USB Legacy" support - i.e. the BIOS emulates a PS/2 mouse and/or keyboard.

That looks better, but I think that the "Win2k"-style horizontal gradient is still nicer... maybe I'm just a sentamentalist. :)

Looks nice! Glad that the ugly vertical gradient titlebars from trunk are not included... I hope those go away forever. ;)
