Release Qemu for Pandora (for rebirth competition)


I thought that using the nubs or an external mouse didn't work using Notaz's SDL? Might any of this code be of use to john4p (after the competition is over natch!) for updating Uae4all?? ;)
 
Who said something about notaz sdl?


Right now we are not using it because it messes up big time, when you change videomodes. We would have to patch qemu to reload the SDL init everytime there is a resolutionchange.


Maybe possible, but without a Pandora i am stuck here right now...
 
Apologies then, my mistake!! :blink: I blame it on 6am starts in work....

But it runs! On the Pandora! With Sound!. I never would have expected this, so even if it is not playable, it still is impressive. :)

I bet, a direct, straight Diablo2 port could run very niceley on the Pandora, if Blizzard just would give us the Source Code. :)

Yes, i think this would be easily possible, but well, they probably never will release the source to this.

Oh well, and I'm really going to freak out some of my favourite Sierra-Adventures (Gabriel Knight 2, Phantasmagoria 1+2, Shivers etc.) will work (incl. touchscreen support).

I ran Phantasmagoria 1 with dosbox and it played great so I'm sure it will be no prob for qemu. KQ6 (speaking of good sierra games) was decent on dosbox as well when I tested it shortly after pickle's release, should be near flawless (minus touchscreen :p ) with qemu judging by mcobit's videos. I can't wait to get my hands on this!


How bout that carmageddon test mcobit? :)

Making Windows 2000 run (rather well) on only 32MB RAM


- By Daniel Iversen,


16 July


2005


There are times when it can and should (sometimes) be done…


installing Windows 2000 on very old computers with only 32 megabytes


(MB) of memory (RAM). I’ve seen 64 and 96 MB RAM computers struggling


with Windows 2000 but if you configure the system correctly it can run


fast and well. Note though that there is no “magic bullet”. Although


your old computer can run faster it will never compete with modern


hardware in terms of performance.


This is a short guide to show you how to run Windows 2000 on such old


computers and maintain a fast (as possible) performing system.


The computer I installed Windows 2000 on was a Toshiba Libretto 110


sub-notebook with 233 Mhz and 32 MB RAM.


Why would you do that?I had an old but very leight-weight small subnotebook that I


needed for after hours support for one of my clients… I needed to


install Windows 2000 to use my mobile phone (LG U8110/U8120) as an


infrared modem to access the


high speed 3G data network. Your reason might be that you have an old


PC you don’t want to throw away and Windows 95/98/Me might not give you


the features you are looking for… be aware though that if Windows 98


meets your needs it is stupid to upgrade because you have lots less


memory to work with when installing Windows 2000.FACTS


Before the tweaks in


this document


Windows 2000 would startup/boot in


30 seconds and you would have between 3-4 MB RAM left for your


applications. The system responsiveness is sluggish.


AFTER the tweaks in


this document


Windows 2000 would startup/boot in 10 seconds


(using hibernation) – which is faster than my 2.4Ghz/400MB laptop ..


and you would have more than 10 MB RAM left for


your


applications. The system responsiveness is rather fast.


performance-post-tweaks.jpg



Figure 1: The performance of my


old subnotebook after tweaks


THE GUIDE


Install the plain Windows 2000 operating system oin the computer.


Keep in mind:

  • DONT install an

    extra service pack (they can offer perfromance and reliability
    improvements on faster computers but on old computers with few tasks
    they are just a bloat). Make sure your Windows installation CD isn’t
    already “slipstreamed” with a service pack.
  • Don’t install multiple languages (i.e. no multiple keyboard

    layouts) as it takes up precious resources… just stick with U.S.
    layout.
  • DON’T upgrade

    from another version of windows. Lots of stuff will be left hanging
    over and the performance will suffer
  • Keep (or choose) the (very fast for old computers) FAT file

    system during installation as opposed to the heavier and more secure
    NTFS filesystem


Removed cursor shadow


I know… maybe not the biggest resource saver (especially because the


graphics card probablky handles this one.


Disable display effects incl color icons


You can run with 16bit color on the desktop (if that is what you


graphics card supports best natively. Be aware though that some


computers can run with higher color depth but the copmuter


processor/CPU (as opposed to the graphics CPU) may have to do more…


but usually 16bit is fine.


Then you disbale high-color icons, you disable fading effects, smooth


fonts and “show window contents” when dragging – in other words,


disable anything fancy
icon_wink.gif



removed sound theme and sound card


Playing sound takes CPU resources and getting sound files takes


memory.. disable sound effects, and even disable the sound card… When


you run on 32MB there are sacrifices that have to be made… I use my


32MB subnotebook for non-sound things so disabling sound card makes


sense because the drivers take up resources.


Disabled (by setting them to “manual” (in case windows needs them))


unneeded services


This is probably the single-most important step after the installation.


Windows loads lots of services you might not need and they take up LOTS


of memory and CPU (considering we only have 32MB).


Disabling following services in the “Control Panel -> Administration


-> Services” makes your computer able to act on the network,


internet and other things while freeing up lots of memory;

  • Remote Registry Service
  • Task Scheduler
  • RunAs Service
  • TCP/IP NetBios Helper Service
  • Print Spooler
  • Event Log
  • Computer Browser
  • IPSEC Policy Agent
  • Messenger
  • Distributed Link Tracking Client
  • System Event Notification
  • Alerter
  • Protected Storage
  • Server


You can also remove these services

  • Infrared Monitor
  • Removable Storage (for USB drives, attachable CD drives etc.)I use the 2 services above but have them disabled. I just created 2

    shortcuts on the desktop to start them… the command to start a
    service is net start “<service
    name>”


Install and use X-Setup from


X-teq


This is probably the second most important step after installing


windows and disabling the services…. This little tool can remove lots


of hidden (and for you unneeded) applications and settings embedded


deep inside windows.


Following changes has to be made using the X-Setup tool (trial version


will do)

  • disabke activedesktop
  • use “Classic” Explorer style(as opposed to only turn off the obvious win2k UI niceties this

    actually reduces the win2k memory footprint further by also removing
    quick launch, right-click on start menu and other features)
  • disallow file and printer sharing
  • Shutdown can auto-end programs
  • Service timout when system shutdown decreasde to 10sec
  • Disable group policy objects (GPO)
  • Disable dr. watson just-in-time debugging
  • Disable “last access” attribute of files (this is important for

    drive/processor speed)
  • disable “secure desktop” patch
  • Disable windows file protection (this is VERY important for speed)


Remove LPT/printer port


Chances are that you won’t have a printer connected to the computer..


Removing the LPT port (in the control panel -> system -> device


manager ) is a good idea … you can still print over the network,


albeit a bit slower (since we disabled the print spooler earlier)..


thats o.k.


- it is all for the greater good.


Disable printer and file sharing


again – its about cutting down on whats running.. do this and connect


to other computers instead of letting them connect to you.


Other registry tweaks found on the net;


”


”HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer”, create a DWORD key “AlwaysUnloadDLL” and set it to 1. Without doing this, your Libretto will use more and more memory even after you close all the open applications. Very cool tweak.“HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\PriorityControl”, create a DWORD key “IRQ8Priority” and set it to 1. This way CMOS access and overall system performance is improved.


HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\SessionManager\MemoryManagement”, set IoPageLockLimit to 1000 (hex) for 64MB. Set it to 4000 for 128MB, 10000 for 256MB or 40000 for 512MB or larger.


”


Install and use Tweak





UI


Tweak UI is an old but good fere application from Microsoft to tweak


certain windows saettings.


Install it and use it as follows;

  • remove all UI effects of windows
  • remove active desktop
  • remove “new documents added to documents on startmenu”
  • renmove “beep on error”
  • reomove most of the icons from the “new” tab




Use hibernation feature


Hibernation allows you to start your computer very fast. A typical boot


process can take 40 seconds.. .resuming from hibernation only takes


10-15


seconds – very much worth doing! (just remember to do a real


reboot/restart every few days to make sure everything gets “cleaned up”)


Install network card


Install the network card in your computer… let windows detecdt the


card and use the “browse” button to find the driver on your


CD/floppy/folder… do NOT run the installation program that came with


your netwoirk card as that will most likely install some resident


helper application (that you don’t really need)


How to use the computer on a daily basis

  • Don’t install a lot of applications
  • Only have 1 application open at a time if possible
  • Don’t work with big (1MB+) files (documents, images etc)
  • Don’t apply O/S patches for security stability or other things.
  • Don’t envy people who has newer software than yours (Windows XP,

    Office 2003, etc) or desktop
    wallpapers for that matter
    icon_wink.gif
    it’s not going to happen on your computer!
  • Defragment your drive regulary


What now?


Next thing is to install office or whatever.. Office 2000 can run on


this computer… make sure though you don’t run a “pure/normal” install


but just copy the files over from anbother installation… this limits


bloat and drivers decreasing overall performance of your system.


Upgrade to 64, 96 or even 128 MB RAM…..
icon_wink.gif
(much more RAM that this


might not


make sense if you have a very old CPU)

Also, did you tried relative images ? May boot r/w performance if the master and the relative are on different cards.


Also, you can bloat around many relatives from one single, clean image.
 
Personally I'd try 98lite - I used to love stripping 98 down to the "bare bones". Once got it down to under 8mb while retaining it's ability to play games - compressed I backed up that OS on 2 floppy discs! MicoXP/Server 2003 may also be interesting for those that like to see stuff running at 3fps. What sort of gfx "card" support does qemu offer? Will there be any chance of say emulating an 8mb directX compatible card, or is it the same 2mb max that DOSbox has?


This does look like it's going to be fun...

Messes up?

Sorry: I mean doesn't work, crashes on start etc.


Edit: More info and testvideos tomorrow.

Yes! I agree with Titan. I use 98lite on some tiny Toshiba Liberetto's that I have.


It can be made very light weight and I am looking forward to trying it on Qemu!
