ACER ASPIRE 3624 WXCi - FINISHED

troisd · July 28, 2006

Howdy!

I just bought an Acer Aspire 3624 WXCi for $399:

Celeron M 380 1.6GHz

Intel 910GML Express

512 MB DDR2-SDRAM 400MHz

40 GB HDD

DVD/CD-RW Combo drive

Graphics Media Accelerator (GMA) 900

14.1 in (1280 x 800)

802.11b/g Atheros AR5005G

Ethernet (10/100 Mbps) Realtek RTL8139/810x

Realtek AC'97 Audio

I connected an external monitor and booted the MaC.OsX.10.4.5.Universal.Install.DVD(INTEL-AMD-SSE3-SSE2) and selected INTEL/SSE3/SSE2/10.4.5_update options and everthing installed perfectly (very slow on the last optimization prior to reboot).

Upon reboot, the laptop hangs on the startup grey apple screen. Verbose mode indicates two places of interest, both a result of Illegal Instruction errors:

launchctl load /Library/LaunchDaemons /System/Library/LaunchDaemons /etc/mach_init.d

and

... loginwindow ... exited abnormally: Illegal instruction

the above in an infinite loop.

I tried a new re-install without the 10.4.5 update and still same problem.

Anyone seen this before?

One thing is to not install both the SSE2 and SSE3 updates. Figure out which applies to your processor and apply only the correct one.

Rammjet:

Thanks a lot! It's my first time installing on a SSE2 cpu setup...

The laptop boots now and goes right into...

NO KEYBOARD ATTACHED screen!

I have no control over mouse nor keyboard (as I would normally expect because real Macs uses USB devices), but I know there is a PS2 kext which would solve this problem. I guess not right off the bat.

I plug in some USB mouse and keyboard I have lying around and continue the registration part.

I get a bunch of improperly loaded kexts:

AppleAC97Audio

AppleAC97AudioIntelICH

ApplePS2Controller

How can I get PS2 mouse and keyboard to work? Is it normal for the mouse/keyboard to not function during install?

Where do I turn on video mirror mode?

Thanks!

Rammjet · July 29, 2006

After you sorted out the SSE2 situation, did you install the 10.4.5 update?

For keyboard, peruse these:

Mirroring is turned on in the System Preferences -> Displays

troisd · July 29, 2006

Rammjet:

After some search I discovered that MaC.OsX.10.4.5.Universal.Install.DVD(INTEL-AMD-SSE3-SSE2) has kext permission problems for ApplePS2Controller, AppleAC97Audio, and AppleAC97AudioIntelICH. After fixing the permissions, it all worked, even sound.

Funny thing is that Profiler states "No Built-in Audio". For that matter, it also states "There was an error while gathering this information" on the Hardware tab.

I have one last problem which I could not find anything on the forum:

I need to boot from external monitor (otherwise I get the BlueScreenOfDeath on the laptop LCD) in order to use the system.

Under SystemPreferences:Displays, there is *no* option for mirroring! (That's why I asked that dumb question)

Under SystemProfiler:Graphics/Displays, I notice the following:

1) In BIOS I set video memory to 64MB but Profiler states VRAM (Total): 256MB. Since it's GMA900 using shared memory, 256MB is not acceptable. My OSX86 is running very slow. Could be lack of memory since it only has 512MB RAM. I did not get a memory upgrade because a MacIntel Mini has 512MB too! Should not be this slow. Gee... my wife's Powerbook G4 667MHz/512MB is faster than my 1.6GHz Celeron M!

2) Displays:

Display: Status: No display connected

570S/580S TFT: Resolution: 1024x768@75 Hz; Depth: 32-bit Color; Core Image: Supported; Main Display: Yes; Mirror: Off; Online: Yes; Quartz Extreme: Supported

From (2) I noticed that OSX did *not* detect my laptop's internal LCD. That is very unusual and I did not find anyone else with this symptom. Usually, it is and all I need to do is enable mirroring and put in a VGA dongle. How do I fix this problem?

Thanks!

Rammjet · July 29, 2006

1) I think the Profiler is lying about your VRAM. Try running several programs and use Activity Monitor in the Utilities folder to see if they use more than 256 MB of real memory. If they do, then Profiler is lying.

2) Try the fabled 2 wire trick using pieces of paperclip or something and see if the video situation changes.

http://forum.osx86project.org/index.php?ac...ost&id=1522

3) Speed: Make sure to delete the HWSensor and TPMACPI kexts in the System/Library/Extensions folder. See the links in my sig for reference.

troisd · July 29, 2006

Rammjet:

1) I think Profiler is lying also. Checking Activity Monitor, I see Used:267 MB, and Free: 234 MB. Adding it up gives 501 MB, leaving 11MB for video display? Anyways, I noticed huge disk activity going on. I also saw VM size: 4.25 GB!! My applications (Safari, Finder, Dock, loginwindow, etc) are using 300+MB Virtual Memory! Is that swap file?? If so, then it is ridiculously high! Usually (from my Linux days) I set swap = 2xinstalled_ram, in this case, 2x512 = 1GB swap. Could the VM size be causing massive swaps and thus explain the slow system response?

2) Lo and behold, it WORKS! My laptop is now running in full 1280x800 internal LCD glory! It is just confusing when other posts mentions about mirroring and then doing the dongle thing. I mistakenly assumed that doing the dongle directly would simply give me the BSOD.

3) HWSensor and TPMACPI were both pre-deleted in the DVD image (how nice). I can only conclude that it is the memory swapping that is causing this slow system.

My laptop is now completely working: LCD, sound, wifi, network, QE&CI...

just the slowness issue is now left to be solved!

Rammjet · July 29, 2006

A typical swapfile for OSX is 64 MB. They are stored in /var/vm. You can go see how many you have.

troisd · July 31, 2006

Rammjet:

I checked on the vm size and indeed it is 64MB. Obviously then, VM != SWAP.

Either way, my laptop is still slow... i.e. during bootup, that initial progress bar moves extremely slow, like 2 minutes to complete all the way. After bootup, the response is sluggish, always with the HDD activity led on. I type something on the keyboard and there is a delay. I click on a menu item, and there is a delay (as in, color wheel delay). But I noticed that once an app is loaded, if I redo an operation, it goes much faster the second time around. Probably because it is already in memory.

I have deleted the HWSensor kext. I tried platform=X86PC at bootup and no difference. I have yet to try the QE2D+Beam Sync (still downloading the enormous XCode image).

1) Do you have any other ideas I may try?

2) Do you think updating to 10.4.6 will help? 10.4.7 perhaps? Is it possible that OS updates will fix this sluggish response?

3) Is it possible that 512MB installed RAM really causes this? I thought 512 was enough to get a perfectly usable system if I kept amount of apps running to a minimum because MacMini (Intel) has 512MB and I doubt Apple will sell a sluggish system.

troisd · July 31, 2006

I think I found a big reason why I am having a sluggish system:

"The key reason for the slowdown is lack of DMA support for your hard drive."

The Disk Test result of 22 is pretty bad, but not as bad as some other people's. I took notice that a score of about 70 is good. Definitely something is going on with DMA support.

How do I go about activating whatever I need to activate (UDMA I suppose)?

Edit: My harddrive is Seagate ST9402112A 4200 rpm Ultra ATA/100 and is correctly identified by OSX as ATA protocol. kextstatus also reveals as loaded AppleIntel915.kext, AppleIntelPIIXATA.kext, and IOATAFamily.kext. Software-wise everything looks good. Xbench score looks bad and usage-wise is terrible.

troisd · August 1, 2006

Oh well... opens my wallet pulls out some cash and buys myself 1GB memory!

Will let you know if this is why my system is slow on boot and system response.

I heard that 512MB on XP == 1GB on OSX

And for that matter, 1GB OSX == 2GB Vista

jackkr · August 3, 2006

Hi,

Actually my first post here, but i have same laptop with exactly same issues. Everything kinda works, but very slowly.. and it feels like hard disk is lagging. I have 1,2gb(800mb free) of memory and jas 1.0.4.6 but that doesnt help much. I dont think its about cpu or mem.

So, if theres someone who can help, I am pleased to hear too.

Oh, and how do i get into darwins prompt? Would like to test those other "platform=" settings.

Man... not what I wanted to hear :-(

512MB will arrived today, and another 512MB tomorrow! But I couldn't imagine how that would help the bootup process to run any faster (about a minute or two during the initial bar progress screen to complete).

I then think it has to do with our hard disk's DMA/UDMA access.

I read that if DMA was off, then Xbench would give results of 2MB/s which isn't our case. But then again, we don't get those nice healthy numbers like 50-70 score.

To get the boot prompt, press F8 during bootup.

Rammjet · August 3, 2006

For QE2D and Beam Sync, follow the links in my sig. You don't need Xcode.

Until yesterday i had only 256mb ram... compared to that +1gb made things faster, but not the way i wanted. Its still sluggish and not too fast.. for example bootup. I hate when that rainbow colored circle comes up ;-)

Hmm. I am pretty sure too, that its has something to do with hd.. just what and how.

troisd · August 3, 2006

Hmm, perhaps there is a drop of hope... you mixed 256MB memory with a 1GB memory. Are they both DDR2/400 (of the same type)?

Does DDR2/400 work at full speed with two different memory size and/or speed?

I will get two 512MB DDR2/533 Corsairs. I will let you know how it works tomorrow.

troisd · August 3, 2006

This is what I found at crucial.com site:

"Do I have to buy the same size upgrade as the memory module currently installed in my computer or can I mix different sizes?

In newer systems using SDRAM or DDR SDRAM memory, you can use modules of different densities with no problem. For example, if your computer came with a 128MB memory module, you can add a 256MB module for a total of 384MB of RAM. However, if you have a "dual-channel" system and want to take advantage of that technology, you will need to ensure that the modules in each memory slot are the same density. "

We have DDR2/400, therefore dual-channel. You are NOT taking advantage of dual-channel.

"If you have a dual-channel platform and you want to take advantage of the performance gain it offers, our advice is to simply purchase your DDR or DDR2 memory in pairs. However, be very careful to order two modules with the exact same specifications; the modules must be identical to each other to perform correctly. "

There you go! My first 512MB memory arrived. Tomorrow I will get another! Stay tuned!

In the meantime I am researching UDMA diagnostic for OSX86...

Where is HDPARM when you most need it???

troisd · August 3, 2006

Here is some nice info I learned:

"UDMA

Short for Ultra-DMA and also known as Ultra ATA, UDMA is a standard developed by Quantum in conjunction with Intel that is twice as fast as the previous DMA interface. UDMA was first introduced in 1998 with the ATA-4 or ATA/ATAPI-4 standard and is capable of transferring data at 33.3 MBps, which is how the UDMA/33 or Ultra-DMA/33 names came about. Since its initial release and the approval of new ATA standards, the below UDMA standards are available.

*

ATA-5 -- UDMA/66, Ultra-DMA/66

*

ATA-6 -- UDMA/100, Ultra-DMA/100

Notice: UDMA/66 and higher are only supported when an 80-wire 40-pin cable is being used. This cable can be distinguished by looking at the ribbon and noticing the amount of wires when compared with a 40-wire cable. "

Since my Xbench doesn't pass 33.3MB/s I assume that my system is running UDMA... *but* under ATA-4 (UDMA/33).

Our laptop is capable of UDMA/100 (ATA-6), i.e. 100MB/s.

The trick, then, is to figure out how to activate that! We're in 2006... not 1998!

troisd · August 3, 2006

I'll keep on adding things I discover in order to resolve this issue once and for all. I've other Acer laptop owners having the same problem.

Unlike NetBSD dmesg log:

I attached my complete system.log for a single boot. Notice the immense amount of "kernel[0]: Default traffic burst: 2048 usec". What is that??

jackkr · August 4, 2006

Ok, to me it seems that it is using ATA/100, but cant be sure. Problem is that dont even know where to start solving this. :-( I think i will update my system to 1.0.4.7 and see if it helps.

Yesterday i put my Acer to pieces and tried that wire overclock thing.. just could get it work.. I'll try again today with some copper wire.
