Been having a poke around, it seems neither LiveCD nor BootCD will boot into GUI (Using latest HEAD SVN), on 32MB.
BootCD will complete first stage installer, but won't boot into GUI to load the second stage setup. LiveCD immediately hangs.
Now, on VMWare, I use Other/Other as the OS Category, and I've been hearing some (like WaxDragon), using Windows XP Professional as the OS Category. I obtained a BootCD of 17751 rev, and tried it on the WinXP setting, using 32MB. First time I tried it, it hung at copying ole32.dll (34%). Second time, I got a STOP error during the file transfer. Third time, however, it completed the first stage fine.
The only difference between the Other and WinXP Pro settings is the inclusion of a USB Controller. I added one to my "Other" setup, and ROS, again, installed fine first time around on 32MB.
Now, for the interesting bit. The error is a pretty constant one, and it complains of No Memory Pages Available. It seems just common to the GUI, seeing as ROS won't boot on 32MB even once Setup is completed. This is the case for both SVN Live and BootCD's.
Something in the GUI is causing a leak
Hi,
running ROS in qemu with ctm and taskmgr as application reports the following memory usage:
MC_CACHE: 3671 pages MC_USER: 2764 pages MC_PPOOL: 448 pages MC_NPPOOL: 4973 pages Free: 20894 pages
PagedPool: 3684 blocks with 1242232 bytes NonPagedPool: 13298 blocks with 11009752 bytes (283 free blocks with 86312 bytes)
70 blocks with 7358512 bytes from NonPagedPool are used for symbols.

I don't think it's a leak, it's just the GUI eating memory.
I was able to boot ReactOS with 13.5MB memory into command prompt and ping, that's about it. 15-16MB got me working FTP and other command apps worked fine. 18MB got me GUI, but almost nothing else would run. 20MB got me GUI with the basic apps working, regedit, my computer, taskmgr, etc. 24MB got me a fully working ReactOS environment that never crashed due to low-memory.
Best regards, Alex Ionescu
Let's keep in mind that the only time Alex was able to obtain these results are in the revisions right after the 0.2.6 release. The versions that worked are noted in the "ReactOS is a fat pig" bug. Also, your Testing Coordinator *still* cannot reproduce TwoTailedFox's results. If anyone else can, I am interesting in hearing about your config.

Alex is still able to obtain these results with his current tree. Alex noticed the other members of the team were not interested in achieving these results, so he has not continued to ensure they are still public.

I'm still surprised it works myself, partly because it sounds like it really shouldn't be possible, given what everyone else is saying.
I'm going to have a butchers on Virtual PC 2004, since I've got a day off tomorrow. I'll compile a fresh SVN copy of the BootCD and LiveCD, and see what I can get working with that.
QEMU 0.7.0 for Windows, with 32MB using r17829, first stage completes again, second stage complains it's out of Swap Space....
Bochs 2.1.1 with 32MB can't create the registry hives, and fails around ~60% on 1st stage install.
Alex, I'm curious to see how you've got ROS booting with such low memory. Needless to say, I'm very much interested to see the same results.

Note that if you do a default build, you'll get a debug build which, at runtime, will load symbol info. Hartmut computed that this takes up 7Mb of memory. If you want to use as little memory as possible, you can do a release build (copy config.template.xml to config.xml and change the DBG value to 0), or you can prevent symbol info from being loaded by adding /NOLOADSYMBOLS to the load options in freeldr.ini.
