One of the reasons I created a blog was to post info that Iearned over the years from other websites in one easy location so that people would learn from me as well. This next bit of info definitely falls into that category.
The Libretto 50CT will kernel panic if you try to boot it into Linux. That's because the laptop does not report the right size of it's memory and then Linux tries to use an area that's not there. In order to prevent this from happening you need to add mem=16m (or 32m if you added the extra memory module) to your append line. I tried this with Damn Small Linux, and it worked perfectly.
Another issue with the 50CT is that it will 16-32MB of your hard drive space when it hibernates. This only becomes a problem if you take the drive out and create a new partition for the drive elsewhere. So f you decide to create the partition outside of the Libretto, you need to make sure that you leave 16 or 32MB of empty, unpartitioned space at the END of the drive.
