I haven't been active for awhile, searched a few topics but no avail.

 

Has there been any progress on SSE2 only CPUS? I know everyone was having problems with the disc rebooting and never making it to the install screen.

Yes its a problem with some SSE2 cpu's not being compatible with EFI. I have a DVD in testing that does not use EFI and has an option to install without it. This also fixes the same problems with the AMD Phenom.

Hi,

I had fully working Leo 10.5.2 First it was Leo4All (updated to Leo4All2), than updated to newest Kalyway 10.5.2.

Yestorday I have change my processor from Caleron D 2.23Mhz (sse2, see3 support) to Pentium 4 Northwood (cache 512, and only sse2). In runs much quicker under vista (i have dualboot), but I CANNOT start Leopard naither from DVD, nor from HDD.

It simply during booting imidately restarts after 2-3 seconds. Have no idea what should I do in such a case. No help found in the net exept such ideas as "try with different CPU".

 

Any ideas, people?

 

Thanks in advance!

 

Spec: Mobo P4I65G Asrock

CPU: Pentium 4 3Ghz Northwood (512 cache)

1 GB single dimm stick (400Mhz)

(all other hardware components including RAM worked under Caleron D 2.24 Mhz)

Well, it is not quite true. I download iATKOS_v1.0ir2, and this distro works. I am not nervous, coz I have time machine backup, so now I try to install this version. Unfortunately this is only in English and I cannot make a simple update. But any way - during the instalation process it starts from DVD without any problems. So i guess - there is a solution for pentium see2 owners, though it is not clearly written anywhere howto.

 

ps. iATKOS_v1.0ir2 DVD runs see3 emulator at the beginnig (seen in verbose mode). And it works! :P

Now I am trying to guess what should I do to transform this emulation to "normal" booting.

Is it an SSE 2 only processor?

 

If so how did you install Leo4allv3 on it? I tried kalyway 10.5.2, Leo4allv3. During the weekend i want to try another method that has more work to it. It involves copying my leo partition from my laptop to a fixed disk in my system and patch it with iAtkos r3.

what do you mean by sse2 only ? do you mean NOT sse3 at all ?

Because installation and running on my old Dell laptop (D800), pentium M, is flawless. It's using the sse3 emulator (I see the message at boot start). It's true it's not the fastest OS running on it (my debian linux is faster for sure) but the diff is very small.

 

The trick to get the OS to boot (installation was flawless, both with leo4allv3 and kalyway 10.5.2) was to not pick up any special drivers - graphics, net - during installation and install the older ACPI stuff (1.0.3 or something like that). For the rest, I left the default options and disabled what did not seem important (language stuff, etc).

 

Then, after I booted it and created an account, I installed the nvidia graphics driver and ethernet driver that would work. No sweat. I have a thread describing the different steps on my tuning OS-X for my laptop, something called "Flawless installation ... (Latitude D800)" (I don't have the link right now).

The problem already starts with booting the different distro's into the installation. On an SSE2 only system only darwin boots. Then as soon as the install wants to get into the install gui (grey screen) the system reboots. The different boot options for safeboot etc etc have no effect. I tried it on 2 different systems with different distro's. And no go on these 2 systems. On my laptop from the office with a centrino duo kalyway 10.5.2 (used same DVD) it boots perfectly into the install gui. So it isn't a badly burned DVD.

Eddie, this is really great news! Thanks for your hard work, all of us stuck in reboot hell really appreciate it. If you need anyone to test your release let me know, as I think I'm a prime candidate. I've tried Leo4all v1, v2, and v3, iAtkos v1, v2, and v3, Kalyway 10.5.1 and 10.5.2, and just about any other leo release I can get my hands on but they all reboot at one point or another during the install boot. However, I have 10.4.11 running on my machine like a charm! So I think you are correct that it is an EFI issue.

 

My processor is an Intel Northwood 2.4Ghz P4, my mobo is an Intel 865PE, 2GB ram, Nvidia GFX5200 video card.

OK folks. After lots of unsuccessful experiments i finally have installed this freaking system on my P4 see2 only.

Chosen Darwin bootloader and available patches (two). No network, no other drivers and patches. Now, i am transferring from time machine my backup. If I succeed - i promise i tell ya.

 

This post is only to proof, that it is possible to install leopard iATKOS_v1.0ir2 on P4 see2 only.

Awesome, keep us informed.

 

People who have gotten there SSE2 only processors to work please let us know, it could help us all out tremendously.

I got Leopard to boot on my P4 2.6GHz Northwood by using Pacifist in Tiger. Right-clicking on the packages you choose to install lets you install to another disk (partition made for Leopard). After the grey boot screen with the apple, my screen turns grey...turns out my video card isn't Leo supported.

 

I used Kalyway 10.5.2. Using Pacifist avoids the install boot loop completely, but you need to be running Tiger already.

 

Maybe this'll work for someone, as far as I can tell it worked for me to install.

Well, hmm... i have enough and i give up for now. This is madness. :/

Right, I can install iATKOS_v1.0ir2 from DVD as a new system.

Chosen - as i said - darwin bootloader x86 + see2/sse3 patches (total 2+1)

I had to switch off second ata hd with ntfs, coz Leo was hanging during loading process.

I had to switch off (in BIOS) my network card (RTL) in other case Leo was hanging.

 

Than i installed kalyway update to version 10.5.2 - without problems. Than - reboot and login without problems.

In this phase: clean system, kboard and mouse (usb) working. DVD working. Sound (A97) also working though i didnt ask for the driver.

So, i decided to restore my backup with programs, drivers and settings (kalyway 10.5.2) - and it was just start of the end :/

I checked out my profile - it looked ok, but applications didnt want to work /errors and known from Windows - "apliccation made illegal operation and will be bla bla".

 

I made next reboot, and got random kernel panics (though this see3 emulation still works).

 

So, dear readers, i am not a Mac geek, i think that i am rather a noob who likes Leopard on my PC with Vista. I can not understand, that creators of such brillant distros of OSX 10.5 ignore users with processors which cannot run see3 commands...

 

The only hope is Eddie11c, coz authors of Iatkos openly stated that they would not develop see2 support any more (or sth like that).

 

I am a bit fuc*ed up, coz i bought this p4 specially for Leo, and i did not know, that such processor didnt run see3 instructions (my much weaker old caleron d DID!)

 

Greetz, now i am going to kill myself :]

I'll give that a try this weekend, I can install Tiger perfectly fine on my machine.

Here is some news. I tried to copy my install (kalyway 10.5.2) from the laptop to the disk of my SSE 2 P4 system. This worked okay. But then to activate i had to use iAtkos distro to install to install the required bootloader. And presto reboot. And yes the kalyway installation started. Untill a KP and a needed reboot. I am now trying to install the IAtkos v1.0i r3 distro without old data. I can confirm tht this distro boots an SSE 2 only P4. I will post later if a have more information.

 

Edit:

 

Plain install of iAtkos also failed in KP. The install works but after rebooting it gives KP's. I tried several tricks with video card. Used the intel onboard, a Radeon 9600 and an GF4 i had laying around. But none with success. I will give it a rest now as i have some other work to do now. Maybe someone else finds a solution. The install procedure can be done with iAtkos v1.0i r3. So that is already a little gain in the problem.

I don't know the specifications on that processor. A quick google revealed that it is a processor which is used in most UMPC's. It is derived from the mobile series. So there is a possibilty that it will work. Are you able to run Tiger on the system with the A110? If not then i would think that Leopard will not either.
