XOpup-2.1 (xopup-203)

XOpup is a Puppylinux 5.1.1-based OS for the OLPC XO-1 ans XO-1.5 laptops

XOpup was developed by mavrothal and 01micko
Mitch Bradley (OLPC) was instrumental in booting puppy on the XO
Paul J Fox (OLPC) was critical in debugging and modifying power management and keyboard function in XOpup.
Anna and Eddie Owens helped with the sound at the initial steps of the project, and ttuuxxx had many helpful comments and encouragement during the difficult start.

XOpup-2.1 is a slimmed down version of XOpup-1.0 and now supports equally well the  XO-1 and the XO-1.5
The main changes compared to XOpup-1.0 are:
To decrease the size and further speed-up XOpup, applications and function that may not suit XO characteristics or used that much,  have been move out of the main SFS file.
These are CD/DVD, Scanner, Digital Camera and printing support, as well as the  Gnumeric (spreadsheet) and Homebank applications.
The main SFS is now under 88MB

All the removed components are provided as pets in the "extra_pets" folder included in the download. They  can be installed as needed, by just clicking the pet.
The 2.6.31 kernel version for the XO-1 is also included as a pet in "extra_pets". Has been reported to handle "difficult" WiFi connections better than the standard 2.6.35 kernel.

XOpup-2.1 can be installed both in a USB key or an SDcard and does not have any special formatting requirements. However when using vfat-formatted media you can only save in an "xopupsave.2/3fs" file and not into the entire partition. Ext2/3 formatting instructions are included in the "Docs" folder of the download if needed. Please be careful reformatting flash-based media .
So:

To install XOpup-2.1 download the XOpup-2.1.tar.gz file (md5sum: 800b9351753fe792a5e14c5c39e0fe16), expand it at the root of an ext2/ext3/vfat formatted USB or SDcard and boot your XO-1 or XO-1.5.

The XO must be unlocked by either having security disabled or copying the "security" folder, with your developer key in it, from your XO's internal storage to the XOpup boot USB/SDcard.
Please do see the XOpup-1.0 build announcement for more info and requirements.

XOpup is using the lupu_devx-511.sfs devlopment files renamed for compatibility to xopup_devx_203.sfs (md5sum:5d38669ca9be6572489450b470eea0c5)


Known issues
1) Alternative screen resolutions are not supported on the XO-1.5
2) While booting from ext3-formatted media, the OFW gives a warning about the ext3 journal needing recovery. Although scary, is harmless. The file system is OK.
