Great news Archer! I hope your NMI problems are over.
Can you share the details of your GRUB configuration? I have a T42p with a secondary Ultrabay disk that I'd like to use with Linux w/o having to mess with the MBR in the main disk which has XP installed.
Thanks! I too hope the NMI issue has been resolved. By all indications it seems to be [so far...
Here is how I setup my ThinkPad T60 with two hard drives. XP on the Main drive, and Ubuntu Linux on the Ultrabay drive.
Step 1) Remove the existing XP drive from the main hard drive bay and set aside.
Step 2) Install the second hard drive in the Ultrabay adapter and into the Ultrabay.
Step 3) Using an external USB optical drive, install Ubuntu to the hard drive in the Ultrabay.
Step 4) Reinstall the XP drive in the Mainbay, and you are finished.
By using this method, since the XP drive is removed from the computer when you install Linux, it’s impossible for grub to write to the MBR. So the installation of Linux is straightforward. No partitioning, or any other tweaks required. Now when you are ready to use your newly configured ThinkPad:
On boot up if you do nothing, XP will boot, just as it did before you added the second hard drive in the Ultrabay.
On boot up if you press F12, you get a BIOS boot menu that lets you choose which hard drive to boot from - the main hard drive or the Ultrabay hard drive.
In addition, this way I can remove the Ultrabay drive, with no errors or problems. I can then insert an optical drive and it operates as usual. I can also take my Linux Ultrabay drive and insert it into my T60p and have a dual boot setup without making any modifications to that laptop. A really great way to have two completely separate operating systems in one laptop. Independent of one another. If one drive goes down, it has no effect on the other and vice versa. The best of both worlds.
Finally, full credit goes to GomJabbar for giving me the instructions to this successful setup.
