I have been fascinated by the Apple’s Mac OS ever since I got to know about it. And when I came to know that I could install it on my laptop, I was delighted. I have been successfull in installing various versions from days of OS X 10.4 [Tiger]. Lately I thought of installing 10.5.6 and upgrading it to 10.5.7 on the same old XPS m1210 which I bought in November 2006.

My previous posts.

Following is a log of what I did and what all errors I encounterd.

I have not created any of the files I used. I have just collected information and resources from the web and the major source of information being these two links on www.insanelymac.com

What all I did

Restarted my XPS pressed 12 to go into 1 time boot menu and boot from the OsX 10.5.6 DVD. [ the iso can be downloaded of well known places ]

Get to the boot menu and -v and boot.

You will get the initial screen.

I already had 10.5.2 running on it so i decided to erase that same partition and install on it.

Then customized the install by following selections :

Patches
Chipset
ICHx Fixed

Network / Ethernet
AppleBC440x

Fix
cpus=1 fix
BatterManager

Video / NVidia
NVKush

Apps
- ASU
- BetterZip
- OSx86 Tools
- Transmission

Then continue to install. I installation checks for the disk errors [ i skipped disk check ]. Wait for 15 minutes or so to finish installation.

On reboot i got the following error

Boot0:MBR

Boot0:error

I had grub as my boot loader so I followed the instruction over here to resolve the issue and add Mac Os to boot loader.

Once its fixed I have the triple boot…. The above link can be used to add XP entry too in Grub.

Boot into Mac OS

Install MacFUSE 2.0.3
Install NTFS-3G to have write capability on other NTFS partitions.
