This is another great Thinkpad. It’s the oldest laptop I own, and making it work well just makes me feel good!
The X40 runs a 32-bit processor, without PAE, which means a couple of things. This limits the amount of RAM that the system can support. This also limits the type of Linux distributions that can be installed. Most distros I have tried use PAE, and will simply not install on this laptop.
The following distributions work on the X40: Antix 19, Puppy Linux Tahrpup 6.0.5.
Before installation I upgraded to an SSD. Since the X40 runs a small 44-pin IDE drive, I decided to replace it with an mSATA card and an adapter.
- 64 GB mSATA SSD
- mSATA to 1.8inch 44Pin 3.3V IDE adapter
(Make sure to get the 3.3V adapter, and not the 5V)
Tested with Antix 19
I also tested with Puppy Linux Tahrpup 6.0.5.
