Perfect Dual Boot: Iatkos 10.5.5i and XP Sp2 Pro

[jtram]

Hey fam,

It took me four days of testing and hair pulling to get my computer to work properly but I currently have a 100% working XP & OS X dual boot system...I'm writing this because I can hopefully help someone out with the easiest instructions I can give and also so I can remember what I did, lol.

 

I'm a stickler for details and I especially want to thank Jae-V for putting up with me. If it was not for Jae-V, this would have never happened.

 

System build completed 12-21-08.

 

OS in Dual Boot: Iatkos 10.5.5i and Windows XP Pro Sp2 32-bit [sata AHCI enabled (NO-RAID support)]

 

Hardware:

1. PSU - PC Power & Cooling 750w S75QB

2. Case - APEVIA X-Pider full ATX tower

3. RAM - OCZ PC2 6400 800mhz DDR2 2 x 2gb = 4gb

4. DVD - Sata Lite-On DH-52C2S-04

5. VGA - ASUS EN8400GS Silent/HTP-512MB Geforce 8400

6. MOBO - GA-EP45-DS3L

7. CPU - Intel Core 2 Quad Q6600 2.4 ghz @ 3.2ghz

8. Firewire - SYBA PCU 1394a 3 + 1 ports

9. Heatsink - Artic Cooling Freezer 7 Pro 92mm

10. Hardrives:

a) Seagate Barracuda ST3250410AS 250gb x 2

WD Caviar 5000AAKS 500 gb

c) Hitachi Deskstar 7K1000 HDS721075KLA330

(Also 1tb add'l seagate storage on the way)

11. I used a spare floppy drive I had hanging around and threw it in the case

 

I can't guarantee anything guys; this is just what worked for me. My biggest problem was getting the AHCI support with XP but almost all those errors were user and not XP. I tried every technique on the net but only one worked. Please read the entire post before attempting anything. Details below.

 

TRY AT YOUR OWN RISK!!!

 

Installation steps: (some of these things are given but I'll explain it like everyone's 5)

 

Bios setup

1. Assemble all hardware, lol

2. Immediately download the latest mobo bios (F10 currently) from the Gigabyte website

4. Put the bios drivers on a floppy

5. Turn on comp and enter bios

6. Start qflash, insert floppy and complete flash

7. Reboot and enter bios again

8. Adjust all O/C settings as desired (if anyone's interested I will post my settings but I think they can be improved)

I) Make sure to give enough voltage to the cpu but not too much (my setting would reset to backup bios because the cpu did not have enough power until I figured that out)

II) Also, make sure Ram is working (my setup hated the corsair ram I purchased but loved the OCZ ram)

III) Enable C1E and TM2, DISABLE speedstep, memory latch = auto, manually adjust ram timing to the ram's specification

9. Save setting and re-enter bios

10. In Integrated Periphials, enable AHCI and enable Sata port 0-3 native mode

 

Before XP Install

1. Have a floppy ready

2. On another computer, EXPLORE the mobo drivers disk

3. Put floppy in the "A" drive

4. Find menu.exe in the bootdrv folder and double click

5. Put the number for the Intel Matrix Storage Manager according to your OS's bit depth

6. Remove Floppy

 

XP Install

1. Turn on computer and Insert XP Disc into Sata Cd-rom

2. Boot from CD and insert floppy disc

3. Press F6 as soon as it's offered (I pressed multiple times as sometimes it would not catch my 1st input)

4. Nothing will happen right away, Windows will continue to load drivers

5. When given the option to specify location, press S

6. Press enter and the floppy will load

7. On my system I only saw four options (this bummed me out until I discovered there are more options when using the up/down arrows to scroll)

8. Use the up arrow until there's the Sata ICH10r AHCI option (Not raid)

9. Press enter and leave the floppy in the drive

10. Windows will either load or give the BSOD; If you see the BSOD, check you bios settings the O/C may be too extreme

11. Select your partition but XP must be on drive C. If XP is not on drive C, there will be problems! (you've been warned!)

12. Finish installing windows like normal

13. On 1st XP boot, install the drivers from the mobo disc except the Sata Raid drivers

14. Install the VGA cards drivers

15. Reboot and XP should load perfectly (IF XP DOES NOT LOAD or FREEZES at the loading stage, check the bios and reduce the O/C values)

 

Installing Iatkos 10.5.5i

1. Download Acronis Disk Director Suite v. 10 and Kext Helper b7 while in XP (put kext helper on portable device)

2. Reboot comp and insert Iatkos 10.5.5i disk into Sata cd-rom

3. Boot the disk and once it finishes loading click Utilities/Disk Utility

4. Select the drive (in my case) or create the partition using MBR

a) MBR is in options under the big partition box on the left side

5. Click ok and when the operation is complete, close the window

6. Accept agreement and click CUSTOMIZE in the lower left corner

7. The settings I used for installation were:

a) Iatkos Main System

PC EFI v 9

c) AppleDecrypt

d) Disable.kext

e) OHR

f) EFI String for your Graphic Card (in my case NVIDIA)

g) Intel AHCI Sata

8. Install and answer questions; after the installation remove the OS X disc and reboot (OS X should auto-restart the comp)

9. Windows XP should then boot automatically (no option to dual boot)

10. In Xp, install Acronis Disk Director Suite

11. Reboot, then install the Acronis OS Selector (in Start/Programs etc)

12. Reboot and this time the options will show up (XP is shown but OS X says "undefined OS")

13. Right click Undefined OS and rename OS X

14. Double click OS X and it will boot

15. After boot, do not run any updates

16. Use the Kext Helper from the portable device and copy it to the desktop

17. Download the audio drivers posted by DonJuanjack on Aug 31, 2008 ( forum.insanelymac.com/index.php?showtopic=123699&st=0 )

18. Open the audio folder just downloaded and run the part that asks to be run 1st by dragging then dropping the linux codec on the patcher next to it , then open kext helper and drag the files from the 2nd part to kext helper

19. Type password and Install

20. Reboot and audio should work

 

Add'l notes:

It took me 4 days of trial/error/ and web searching to get this working. Now the 1st thing I'm doing is typing it all up; I hope it helps you guys with your dual booting lust.

 

I have decided not to update to 10.5.6 because I always like to wait a month for people to say what the bugs are. It's better to have a running system than the latest brick.

 

Some generic O/C figures:

PciE = 100

Multiplier = 350

Ram divider (in advanced settings) = 2.00B

Memeory latch = auto

Enable C1e and TM2 and DISABLE speedstep

 

Once again, I hope this helps and good luck fam!

Hmmm, I may have to try this tonight. I'm going to try my best not to screw up my XP partition though I will post back with success's/failures.

I'm trying to get it working now. Dual boot with Vista. I'm getting the Apple Screen with circle crossed through symbol.

[jtram]

I'm not a pro,

 

I know it works with XP...not sure about Vista....did u install iatkos 2nd...? There are some other threads about vista and iatkos dual boot...maybe they will work better.

Thank you for making the effort to post the steps Jtram. I was researching for a Quad setup and your post from "Buying Thoughts" plus this have been extremely helpful. I am basically going with your setup as it meets all of my needs and has already been tested by you. I will let everyone know if I encounter anything that Jtram hasn't already covered.

 

Can you please also post your OC settings?

[Dude27]

Hi, Jtram....

 

Thank you for your guide, I successfully installed IATkos 5i following it but when I boot OSX, darwin boot ok, then apple white logo and then after a little time of processing (gray screen with little round bars), it shows me the apple multilingual reboot screen.... Do you have any idea? can you post a normal optimized (non OC) bios template that I can follow?

 

My spec:

EP45-DS3L Bios F9

4GB DDR2 800 Mushkin (EM2) non OC

E8400 (duo core 45mm 3.00) non OC

EVGA Nvidia 9800GT

Sata HD 640HD WD partionned in 2

Sata DVD burner Sony 20x

 

Thank for any help!!!

How do I disable speedstep in the bios, it is a important for the process to work? could it be my graphic card? I tried NVinject without success. Maybe I should try the EFI 8800 (I heard it works for some ppeople)...
