 There is NO REASON to expect everyone to adopt the latest and greatest

 un-modified MacOS X on non-Apple hardware.

 Perhaps an unintended side-effect of its adoption of NeXT OS and its open

 After all, the kernel originated at the University of California -

 So what are the best drives and cards for scsi?

I agree with Dan, a SATA PCI card and 10K SATA (Raptor) drive is fast
and reusable in G5, MacPro, and PC machines. I do think SCSI drives
are cheaper right now. There are ATTO UL2x and UL3x cards for under
$25, 15K 36GB drives also around $25. They can also be reused in G5s
and other machines. The advantage of SCSI drives over IDE isn't so
much in the transfer speed as it is in the latency  seek/read/write
times. I don't have specific benchmarks now as I'm onto a MacPro, all
my SCSI machines are in storage (I probably should give them away).
But I've put fast SCSI drives in Macs from a 7200, beige G3, Smurf G3,
PCI G4, AGP G4s, etc. and they have always made noticable real world
speed improvement.

Re: hacking for a slimmer world

2011-11-16 Thread Bruce Godfrey
I have a 15k U320 SCSI drive booting my system now, whereas before I had 
the slower of the two IDE drives in that position.  The computer is 
definitely more responsive now.  Applications open faster and documents 
save faster.  Overall boot up time from being turned on isn't much 
different, but when the computer is on and I am just logging in my 
desktop appears faster.
I do not have a comparison between the SCSI drive and the faster of the 
two IDE drives at the moment.  I am thinking of putting another fast IDE 
drive in here and cloning my old system drive onto it and then swapping 
them.  That would make for a better comparison.


As for YouTube, I have a question about that -
How much difference does the video card make in playing Flash stuff?  I 
used to have a Beige G3 with Panther on it and a Radeon 9200 PCI video 
card.  You could easily watch DVD movies on it, but YouTube was 
sketchy.  This MDD has a 9800 Pro.  YouTube works fine unless it is 
large HD video.  Sharing a desktop in Skype is horrible.That makes 
me wonder if Skype uses the video card at all.  And it makes me wonder 
how much Flash even uses a video card.

Very little. Flash is almost entirely CPU bound. It's faster on your G4 versus

Re: hacking for a slimmer world

2011-11-16 Thread broosg
I like the SATA drive idea as well.  A couple of weeks ago I found out you can 
have it both ways.  There is a simple cable adapter made that you connect to 
the 68-pin SCSI card and it leads out 4 SATA cables.  I have not found anyone 
who has tried these, but the discussion on this web page indicates it works in 
servers where these folks have tried it.

http://www.dealextreme.com/p/4-in-1-sata-to-scsi-hard-disk-data-cable-1940

The nice thing about this is that you can use a SCSI card that actually runs in 
64 bit PCI mode that was made specifically as a fast HD adapter for the G4s as 
your SATA adapter.  I can find no SATA adapter that is 64 bit PCI, so this 
might just make a faster interface for a SATA drive than the SATA cards out 
there.

I think that the advantage of using SCSI drives is not only in the  
transfer speed, which as you say is equal to one of your newer IDE  
drives, but IDE uses more CPU DMA to run than using SCSI which frees  
the CPU up from managing the data transfer.  I don't know all the  
details as I am not a technical guy (not too much anyway), but when  
faced with limited CPU power, SCSI drives will always be better than  
IDE from what I have read in the past.


This will speed up your G4 PowerMac, as it will have more CPU  
resources to work on other tasks, instead of using a chunk of it's  
power to transfer data over the IDE bus.


I have several ATTO fibre optic controller cards pulled from Avid  
Meridian audio/video editing MDD G4 systems, if anyone is interested  
in getting one.  I think the max transfer speed for them is faster  
than your 80MB/s, but then you need a hard drive or adapter that  
converts drives to fibre optic, which I am unfamiliar with, as the  
editing systems did not come with the storage drives that the fibre  
optic cards connected to.


Not sure how you are going to test the speed improvement you can get  
from using SCSI drives instead of IDE, when both drives are  
transferring data at the same speed, but as I said above, your G4(s)  
should have much more resources available when using SCSI than IDE.

I have a box full of SCSI-3 drives, but they are all smaller sizes,  
only 18gb, 36gb  73gb drives.  I would suggest if you are going to do  
this to have a faster system, put MacOSX on the faster SCSI drive and  
use a larger IDE drive for storage of your large files, like videos  
and huge iTunes libraries.  SCSI drives are not yet really cheap, or  
cheaper than IDE drives.  Finding large SCSI drives will likely be  
expensive and you won't find them as large as the current IDE and SATA  
drives.  I don't know the speed of, or availability of SATA  
controllers that will work in a G4 PowerMac, but that might be a  
better choice, instead of searching for old SCSI hardware and drives.

(read and write cycles are usually quite different)!  The drive's 
hardware cache has has be large enough to be able to buffer 
sufficient data to keep both the mechanism and i/o bus busy.  And the 
i/o bus, be it IDE or SCSI or ..., has to be able to throw the data 
quickly.


In my experience, the drive's capabilities are usually the bottleneck.

And be careful of the version and bit widths of the i/o bus. 
Firewire, btw, is actually a form of SCSI 3.


Wikipedia has some very nice articles that include tables comparing 
bus speeds...


As far as getting the best performance overall...  Optimize speed, 
capacity, and especially cost.  Your best bet is a SATA controller 
and 7200rpm or faster SATA drives.  That way the drives are 
inexpensive *and* usable in future machines!

This isn't Linux. People don't normally kernel hack OS X and rebuild
their kernels. I suppose if you really wanted to, you could hunt down
the Darwin source code and build a custom kernel with it. You'd
probably be missing some key functionality, though, because I believe
Apple kept quite a few proprietary bits to themselves.

For stripping out unneeded languages, I believe Monolingual is the
app. It breaks some commercial applications, though. There's also a
utility to strip out the Intel code in Leopard, but I can't recall
it's name at the moment.

For improving performance, try adding some RAM (though you may be at
the upper limit for that G4) and a bigger/faster hard drive. Make sure
your Radeon supports Core Image for the best UI experience with
Leopard. Radeon isn't enough - we also need the GPUs model number,
usually something like 7500/9600/9800.

Sure they do.

Custom kernels exist for ALL x86 versions of MacOS X.

I am presently running mach_kernel_non-atom on my Shuttle SP35 which has a
Pentium 4 541 processor.

This proc supports EM64T and hyper-threading, but not SSE4.

With mach_kernel_non-atom, I can run any version of Snow Leopard as this
kernel is based upon the SL kernel which Apple is REQUIRED to deposit in
the open source repository. SL believes I am running on a 3.2 GHz Core
Solo, and SL is perfectly happy with that.

I am presently running mach_kernel_atom.10.7.1 on my Supermicro Atom 330
Server.

This proc also supports EM64T and H-T and also SSE4, but not certain
features which make it a Core 2 Duo.

With mach_kernel_atom.10.7.1, Lion and Server Lion believe they are
running on a 1.6 Ghz Core 2 Duo.

Others have hacked the kernels for older procs, and even for non-Intel procs.

MacOS X kernel hacking is alive and well, just as OS hacking was alive and
well in System/360 OS/360 (1965) through z/System z/OS (currently).

In principle, I agree with you. It is possible to hack your kernel,
it's just not commonly done for PPC. I used to build custom monolithic
kernels all the time under Linux kernel 1.2, but the need diminished
as more functionality was added to the kernel and the ability to use
modules was added. I've also seen a *few* custom kernels on Hackintosh
ISOs, but I've never had or felt the need to hack the kernel myself. I
think DSDT hacking is more common, though again, it's not something
I've had to do. Maybe I'm  out of touch with the Hackintosh scene,
but I really think Darwin PowerPC kernel hackers are few and far

DSDT hacking is an essential activity with Hackintoshes.

There are as many distinct DSDTs are there are distinct mobos.

And, even within an Intel Northbridge and Southbridge complement, each
distinct mobo might require its own customized DSDT.

Basically, you use Ubuntu Desktop to grab the unmodified DSDT and save it
to a USB flash drive. You do not need to install Ubuntu to do this, just
boot a temporary version, usually from a CD but with no hard drive.

Once dsdt.aml has been written to a USB flash drive, you sneaker net
that instance to a working version of an Intel-based MacOS X. Could be a
real Mack, but it is more likely to be a Hack.

Once on the Mack or Hack, you launch DSDTSE, ideally the 1.4.3 version
which has the latest English commands (the developer is Brazilian) and the
compare facility.

THEN, you start to apply the numerous mods to support MacOS X.

There are many usual ones, and also some special ones.

With experience comes the facility to edit a DSDT by eye.

Otherwise, and especially for a beginner, there are several Guides for
DSDT editing.

I wrote the one on AMI BIOS DSDT hacking.

Others wrote the ones on Award BIOS DSDT hacking, but I revised and
extended (and, yes, corrected) several of those.

Then, you compile the dsdt thereby producing a new instance of dsdt.aml,
and you use that with certain so-called kernel extensions (kexts) in order
to boot and use MacOS X on a Hack.

The process is by now well understood, and a new x86 product never brought
up on MacOS X before can possibly be running MacOS X within 30 minutes.

It took no more than that for my latest Hack, a Supermicro Atom 330 Server.

Hacking

2011-11-12 Thread David W. Morris
As Eric stated before, hacking MacOSX's kernel is not something most  
people would suggest or think of doing to get more speed, specially  
the PPC Mac kernel.  Some of my friends have modified faster ATI  
Radeon video cards, like the 9800Pro, or FireGL X3, or 800XT to work  
in the older AGP slot in your MDD G4 PowerMac and reflashed PC  
versions of those cards (which can be bought for much less) with a Mac  
bios file.  I think that maybe the 800XT is the fastest video card you  
will be able to convert to use in your MDD G4 PowerMac and you already  
have the RAM maxed out at 2gb, so the only other thing I could suggest  
is to get a SATA controller card to use faster  larger hard drives.


Not sure what else I would suggest for speeding up MacOSX on your MDD  
1.25GHz G4 PowerMac, but if you want some real speed from your OS on  
that computer, take a look at MorphOS2.7 at http://www.morphos- 
team.net/ or read about the Lightning OS at this article on OS News http://www.osnews.com/story/15209/


Lastly, I have the exact G4 PowerMac as yours and I ordered a Dual  
1.42GHz G4 processor board to replace the Dual 1.25GHz G4 CPU's, which  
I am thinking of over-clocking to 1.5GHz or 1.67GHz.  I think the Dual  
1.42GHz stock Apple part with it's 2mb of L3 Cache over clocked is a  
better choice than a Sonnet Dual 1.8GHz with zero L3 Cache.


Good luck with your speed up efforts on your MDD PowerMac and let me  
know what you decide to do.  Messing around with older systems and  
trying to get the most out of them is a fun hobby.


Regards,
David

 Messing around with older systems and
 trying to get the most out of them is a fun hobby.

As is messing around with much, much NEWER systems, and getting them to
work on the latest and greatest version of MacOS X.

There is NO REASON to expect everyone to adopt the latest and greatest
hardware from Apple, when Apple actually makes it SO EASY to run
un-modified MacOS X on non-Apple hardware.

Perhaps an unintended side-effect of its adoption of NeXT OS and its open
source (legal) requirements.

After all, the kernel originated at the University of California -
Berkeley, NOT at NeXT or Apple or whomever.

If you don't regularly use all your installed ram, how 'bout a RAM Disk?

OS X is quite thrifty.  It already only loads what it needs, and even 
then mostly not until it's actually needed.  About the only thing 
that can slow it down is stale or corrupted caches.  An app such as 
AppleJack can fix that easily.

Sorry to bring bad news but - AFAIK - OSX will NEVER be snappy on a G4.
If you want a really snappy OS on your G4, better use OS9. :-)

I just went from a G4 DA 1.4 GHz to a G5 2.7 DP, both with OSX 10.4.
OSX doesn't feel snappy even on the G5...! Responsive, yes, but not snappy.
(and, of course, it has always been sluggish on the G4)

So, IMHO, there's no magic wand to make your G4 superfast...
(save for transplanting an Intel Core 2 Duo CPU in it ;-)

Some people here is very fond of hackintoshes (PCs hacked to run OSX).
If you're short on cash and like to tinker (and study), that might be a
viable route.

Coming back to reality...
AFAIK Leopard is not well optimized. Tiger (10.4) could be (moderately)
faster on your Mac. Or maybe even Snow Leopard (but I'm not sure about
this).

 and everything that doesnt need to
 run or be loaded, needs to be killed. So any ideas?
You could use Activity Monitor to check what is getting more CPU time.

I don't think you can kill much, thou; but, maybe, you could find that
some app is CPU heavy, and you can find something lighter to substitute
with.
E.g., I found SoundJam and MacAmp Lite are lighter than iTunes.

 am using some usb apple  pro speakers
I wonder if USB speakers put a load on the system... and I think they do.

Not much study is required these days.

Professionally written Guides are available for a great many
configurations from netbooks to enterprise-level servers.

Most of the tools are now GUI and some require just a one-page cheat-sheet
to go from bare hardware to a booted and fully functional Lion system in
under an hour.


 Coming back to reality...

Hackintoshes seem pretty real to me.

Lion and Server Lion, running on a PC with NO modifications whatsoever to
either the PC or to Lion is a reality.

With prior versions of MacOS X Server, the software cost many times what
the hardware cost, and the temptation was there to use a flavor of Linux
for one's server. Alas, the learning curve for Linux ... any flavor,
server or not ... is VERY steep.

But with Server Lion, the software costs a fraction of the hardware cost,
so there is really no reason not to run Server Lion, and then to get all
the benefits of Lion along with it.

For a long time I heard Linux lovers claiming their OS had become easy and

IMHO, that's not true, by a long shot. But they are so much in love with
their OS, they can't see their own geekiness is far from the common user.

Re: hacking for a slimmer world

2011-11-11 Thread peterhaas

 Some people here is very fond of hackintoshes (PCs hacked to run
 OSX).
 If you're short on cash and like to tinker (and study), that might be a
 viable route.

 Not much study is required these days.

 You sure? Aren't you underestimating your own know-how? :-)

Perhaps my perspective is different, or perhaps distorted by a space-time
continuum.

I spent more than 30 years in professional employment in IBM System/360,
System/370, System/390 and z/System mainframes, both hardware (some of
which I designed, for my then-employer, Amdahl Corp) and software (where I
was a widely-acknowledged subject matter expert in many of that OSes'
components).

Heck, Lion and Server Lion, on Hacks, is child's-play compared to the
learning curve with a mainframe OSes such as OS/360, OS/370, OS/390 and
z/OS.

At least eight years of continual study just to achieve a functional,
journeyman level understanding of the externals, much less the
internals.

Throw in a decade or two more for the internals.

Re: 10.3.9 hacking

2011-10-22 Thread Andrew Owen
To me Panther was the first version of OS X that really nailed it. Then they 
started adding bloat like Dashboard. It runs GarageBand 2 (also my favourite 
version for functionality against bloat) with the most available resources. 
And PPC has always been better for time syncing than Intel.

I hope someone comes up with a working PPC Mac emulator that runs 10.3.9 
before the hardware gives up the ghost, as otherwise I'll be running my 
legacy software on a virtual Windows box.

Re: 10.3.9 hacking

2011-10-22 Thread Andrew Owen
Except that Apple doesn't like GPLv3, so the gcc you get in Xcode will 
forever be a fork of 4.2.1.

So far I've managed to build the gcc 3.4.6 using the version of gcc 3.3 
included with Xcode 1.5. Going straight to 4.6.1 was never going to work. I 
then used that version of gcc to build the GNU core-utilities. 4.6.1 still 
doesn't want to build, so I might give the GNU version of 4.2.1 a go. Apple 
may not support 10.3.9, but GNU still supports Darwin-ppc, so I hope that 
with a few intermediate steps I should be able to update the UNIX tools to a 
fully up-to-date set.

 Explain please dropped in the graphics from Lion.  Lion is an x86 
build and your Mini is a G4.

They're just graphics. They're not CPU dependent. Sure, Panther doesn't use 
the 512x512 icon definitions in a .icns file, but the file still works. Had 
to design my own MacOS 9 folder icon, and I noticed that the folder icons 
are slightly lighter in Lion than they were in (Snow)Leopard.

This is interesting. I thought they were normally built against  
certain other dependencies on other kexts, and that often newer kexts  
wouldn't load if the kexts it was dependent upon were too old.


Are you certain these are actually loading? Do they show in  
Terminalkextstat?

10.3.9 hacking

2011-10-14 Thread Andrew Owen
Hi folks,

I've just stepped over from the Panther list, which is a little slow these 
days. I'm in the process of hacking 10.3.9 on my G4 Mac mini to be a little 
more current. So far I've dropped in the graphics from Lion. I've now moved 
on to updating the UNIX tools, starting with GCC. I'm aiming to get some 
slightly more recent software working under X11. If anyone is interested I'd 
be happy to continue posting about my progress.

Cheers!

well the very first thing I'd do is move up to at least 10.5.8; that will get 
you much more up-to-date almost immediately.

Apple's 10.3.9 is the last version that allows me to continue using my SE/30 as 
an HFS file server.

I have moved most of my serious efforts to ubuntu Linux which has little 
trouble communicating with my SE/30 using Stairway's NetPresenz. My G4 runs 
VectorWorks and I need it but that's about all. I keep hoping that the open 
source guise will come up with a CAD program that works.

And, of course the lady of the house has a brand new iPhone 4S and runs Lion on 
a portable and a desktop. The best I can do is a login account on each where I 
can use Terminal.app. Gestures prove to me nothing more than that all iOS boxes 
are female. I gave up understanding the proper motions long ago.

I'm preparing this on an 8500 running OS 9. It works well and I understand it. 
That's more than I can say about Apple's mail.app that continues to send me 
messages which ignore all of RFC-2822.

Count me as very much interested in your efforts.

Hacking cellphone pics from Motorola flip up cell phone to Powerbook G3 Pismo

2009-11-10 Thread Dwight Hines
I need to download pictures from my cellphone directly to my pismo.  It is
way too expensive to email them from the cell phone.

The phone has a usb port that is used to charge the battery and a port for
headphones.

I own the phone so it is ok to hack it physically.  Has anyone done that?

Please help.
