Enable iBook multiple monitor support System
The German website macparts.de/iBook has posted instructions (in both German and English) to enable monitor spanning on the iBook in OS X. With a few firmware commands, one can be enjoying two seperate workspaces with an iBook and an external monitor. I'm using it right now and it works great!

[Editor's note: Please read the cautions on the instructions page before proceeding! I have not tried this one, and probably won't because I tend to be overly cautious about modifying hardware...]

Which iBook ?
Authored by: SonicMcTails on Oct 24, '02 10:52:03AM

I may try this, but I\'m not sure what iBook this is for. I have the 500Mhz, white iBook, will this work on it ?

Which iBook ?
Authored by: n9yty on Oct 24, '02 11:06:45AM

It works great ONLY on the 700Mhz White iBook with the Radeon graphics chip (RageM6 in the Apple System Profiler).

At least that's what I get by reading the page. Mine is that model, and it worked fine here. Be careful, though. A bad typing error, or other mishap *could* render your machine fairly useless. Some have, from the web site reports, and they haven't found a fix yet. <gulp>

Which iBook ?
Authored by: vogunaescht on Oct 24, '02 11:45:14AM

In that case you just need to type

set-defaults (press return)
reset-all (return)

in OpenFirmware to clear the variables you have set by this hack.

You can reset all values by zapping your PRAM/NVRAM--reboot while holding down the Cmd-Opt-P-R combination until the iBook "bongs" a second time.

can you switch from mirror to span and back?
Authored by: adolph on Oct 24, '02 12:29:30PM

This is really tempting, but I often do powerpoint presentations. Can I switch it back to mirror in the gui? Or do I have to go back to the open firmware and restart et al?

Thanks!

Authored by: Demani on Oct 24, '02 01:37:50PM

It works just like it would on a powerbook- you have complete control over it. It even seems to support up to 16x12 on the external port- very nice indeed.

It does make these machines much more lovely for doing web work, programming, or any of those multi window type uses. Apple should just support it from here on out officially- the cat is definitely out of the bag.

I doubt it. According to the page, "From reader feedback that I got so far I and from some further observation I conclude that the 15" iMac G4, the eMac and the Rage iBooks don't support this feature." "click here for some more details."

Not for Rage-equipped iBooks (2001 Dual USB 500 & 600)
Authored by: mustang_dvs on Oct 24, '02 02:21:11PM

Don't use this hack on a Rage chipset iBook!

From www.rutemoeller.com/mp/ibook/ibookrage_e.html:

Information for owners of Rage-equipped iBooks

Many people were wondering if there is any way to use an extended desktop with their older white iBook without the Radeon graphics chip.

Unfortunately I have to say that there currently is none. It also doesn't seem to be very likely that there will be one in the future. The reason is that the graphics architecture in the newer (Radeon) iBooks is different from the previously used one. If you look into the device tree of your Rage iBook you will find only one graphics controller (below the pci0 node). The newer iBooks, however, have two individual controllers listed which are combined by a parent controller. This is the same way the graphics system is organized in the Powerbook models. In order to allow only mirroring on the iBooks Apple uses a variable (defined in the firmware) that the graphics driver reads when it is loaded. The driver then to limits the output depending on the value of the variable. Since the older iBooks only have one logical graphics controller the value of the variable doesn't matter (it's not even defined in all models). To get the older iBooks to allow an extended desktop it would be neccessary to massively patch the firmware so that it lists both controllers under one parent (this, however, can only be done under the assumption that the hardware allows this which I don't know for sure).

Addendum to above post
Authored by: mustang_dvs on Oct 24, '02 02:23:53PM

(from the same site)

Caution: Some older iBooks might not like this patch and die!

Please be aware that the firmware patch described at the main page of http://macparts.de/ibook will have no effect on your iBook. However, there is the possibility that you (more or less) permanently damage your computer. I have gotten some reports of iBooks owners (all 600mhz Rage versions) that they were not able to boot the computer anymore after they applied the firmware script. Resetting the power manager and nvram did not resolve this. We are currently investigating this issue and will post more information as soon as it becomes available.

O.K. How bout a 600Mhz iBook w/RageM6
Authored by: iprogrammer on Oct 24, '02 03:15:27PM

Does anybody have this working on a 600Mhz iBook with a RageM6 video card? The Apple System Profiler is confusing me... I think that the machine has a Radeon video card in it(it is supposed to, I just bought it last month), but I am not sure since the Profile lists the card as an ATY,RageM6.

Also, in article on the website they mention there being 2 nodes in the video card tree under the PCI heading in ASP and I only have one. Oddly enough, I seem to remember there being two nodes in the tree before I upgraded to Jaguar. Weird...

If anyone has this working on a similar system, an acknowledgement would be vastly appreciated.

O.K. How bout a 600Mhz iBook w/RageM6
Authored by: AgBlue on Oct 24, '02 04:37:30PM

Yes I believe the ibook you are talking about does indeed have a Radeon card in it. My iBook 700mhz reports the same card model as yours, ATY, RageM6. It has 16mb of ram on the video card. I think one way you can tell which model you have is by the side where all the ports are. If you have a small paperclip reset button above the headphone jack, then you have one of the older, 500mhz-600mhz model (which does not work with the hack posted.) The newer, latest models do not have this paperclip reset hole. These are the 600-700mhz models that will work correctly with the hack. Can anyone confirm that this is indeed how to tell the two apart? Thanks

Danny

O.K. How bout a 600Mhz iBook w/RageM6
Authored by: Dave Cheng on Oct 24, '02 11:36:43PM

I can confirm that this does work on the G3/600 iBook (16 VRAM). In fact, I am typing this on the extended desktop running right now at 1280x1024 at 75 Hz on an external CRT.

I'd be interested in finding out what the limitations are for driving external displays, e.g., whether it can do 1600x1200 at 75 Hz in 24-bit color. Anyone try this? I'll give it a shot on a few LaCie and Studio Displays this Saturday and report my findings.

FYI, my graphics adapter is listed as RageM6 in the System Profiler. The standard NVRAM reset (OPT-CMD-P-R at boot) seems to reset everything back to the factory state.

Authored by: dukeku on Oct 26, '02 09:15:52PM

I'm wondering about this... I'm not sure if my 'book will work, it's the 700 MHz one with the larger screen. I'm running Jaguar, and when I look in the system profiler it says RageM6 for the graphics card too. Would this work?

Works Great!
Authored by: bmerlin on Oct 24, '02 06:03:51PM

I just did this to my 700MHz 12.1" iBook and had dual-head in a matter of minutes!!! I'm sure anyone complaining (who definitely has a Radeon iBook) did it wrong. I typed everything in exactly as told. This is the sweetest iBook hack I have seen yet. :)

for those who are unclear
Authored by: cichlisuite on Oct 24, '02 06:14:36PM

based on what the original article states, it is not recommended you try this 'trick' with an original 600 mhz iBook (dual USB). it is unclear though if the new 600 mhz iBooks (now the base model) will work. I would say that if you have the chipset with the 16MB VRAM, you're ok.

Coolest thing since sliced bread...
Authored by: iprogrammer on Oct 24, '02 08:51:02PM

O.K. despite having sweated bullets for about 5 minutes, this has to be the coolest thing since sliced bread. Just for the record: yes this does work on new, 600Mhz, base model iBooks with 16MB ATY,RageM6 (ATI Radeon) video.

Furthermore, this confirms my suspicion that the iBook is the greatest laptop on earth. :)

Thank you for bringing this hack to my attention!!!

P.S. lets just hope that Apple doesn't figure out a way to kill this mod in a future software update.

Authored by: Dave Cheng on Oct 24, '02 11:40:08PM

I certainly hope Apple doesn't take measures against this in future updates. I'm sending my iBook in soon for repair, so I'm afraid I might have to find out the hard way. (The mechanical switch which sleeps the computer when the lid is closed is apparently broken. The iBook stays on even with the lid fully closed, which is damned annoying...)

broken mechanical switch which sleeps the computer
Authored by: logo on Oct 25, '02 04:00:27AM

<offtopic comment=Sorry!!!>
Hey!
Maybe you can exchange the iBook with somebody else's, who would love to have this feature. I've heard of many people complaining that they can't close the lid without putting their iBook to sleep!
(Besides the drawback of the bad cooling if the lid is closed :-( )
I occasionally would like to have this too, eg. on the bus using my iBook as an iPod to listen to mp3s...

No QuartzExtreme with this hack
Authored by: sebid on Oct 26, '02 08:43:10AM

I noticed that there is no QuartzExtreme acceleration on the second display. So I checked with "QuartzExtremeCheck". The strange thing is that it says none of the displays is accelerated. When I switch to synchronize Displays they are. But from my personal experience the internal iBook TFT is accelerated.
Anyone got the same results?

No QuartzExtreme with this hack
Authored by: drsmithy on Oct 28, '02 09:48:19PM

Assuming this is the same situation as the older TiBooks, it is because the Radeon only has 16MB VRAM, which is split to 8MB per display when "spanning" is enabled. 8MB is less than the 16 required for QE, so it is disabled.

I've just done some searching through Apple's developer site for any hardware notes on the latest round of iBook models. Unfortunately there is nothing there for the November 2002 models. I'll be checking back over the next week or so and hopefully we can glean some info from the documents once they're available.

I've done the hack, and my iBook (700mhz model) now picks up the other screen, allows me to set the resolution for it, _but_ it just mirrors my 'book display. Is there any way to enable it to be a second desktop space? (ie. multiple monitors)

The monitor i have connected to it is an old VGA sony monitor.

Authored by: supersonic on Dec 12, '02 05:13:26AM

helloo.

i just tested the crack. but. strange thing.
when i boot my IBook in OS 9.2 i have "extended dektop" in the boot time.
when he finished loading the OS, i have a mirrored desktop.... (There are also no point in the controll center to change it, he shows 2 monitors, but only for colour and resoloution change!)
In the Boot Time of OSX. i have two different Screens, one with the OSX loading Screen, at the second monitor, the is ony a grey screen.
After logging in, NO extended desktop. Nothing the Change in the Preferences.

ok. it seems to me, that the Crack works, but something in the OS ist stopping or disabeling the crack.... is that possible?

Ibook 800, 32 vram, 640 mb ram.
OS: OS X 10.2.2 and 9.2

ps: sorryy for my bad engl ;-)

Dual Display with iTunes
Authored by: kantellopo on Nov 10, '03 07:45:05PM

For some reason if I am running a full screen visualization in iTunes (v4.1 (52)) with a computer monitor hooked up and close my computer (put it to sleep), upon reopening, i press the 'escape' key and am able to run two displays in os 10.3 without doing any harm to the computer (i hope).
Has anyone else heard of this? It is probably a good alternative to messing with the firmware or anything...
This leads me to believe that somewhere there is an (undocumented) API call to do this? I hope this helps!
