Here, I have reproduced a read me file of Pearl Linux since I could not find the user name and password.
It is an Ubuntu Derivative which has a Mac Os appearance and is 1.5 GiB.
At the login screen please type "custom" as the user name hit enter then for password lease that field blank and hit enter.
Found a small issue with the fonts not looking correct and I thought I deleted the .iso but I guess not.
All you have to do if you already downloaded Pearl is go into system settings and change the font from Veranda 9 (?) to Ubuntu 10 and this is important,
On Rendering check the box to left, Hinting change to slight and Sub-pixel order change to RGB. That is the only change that was made.
Their will be more of a README file coming soon.
