  • flameman: i found problem in adding text label ... how to do it ?
  • Prpplague: there is plenty of documenation on the page, simply click the "Editing Help" option at the bottom of the text entry window, or simply go to http://www.elinux.org/Help:Editing. if you intend on doing a complete rework of a page, start a NEW page. if after you are done it is a better page than the original, someone will add a pointer to the new page, but we will NEVER delete the old page.
  • flameman: ok. i will never delete the old pages, I've uploaded all the new pages i could, they are missing of attachments, i will complete them.

  • flameman: How to remove files uploaded ? i've uploaded 2 files i need to remove: name changed
  • wmat: you can't. Simpy re-upload the files with new names, if necessary. But if the only change is the name, it'd be better to change the references.
  • flameman: ok, i will reupload. But if i remember right, the old wiky was able to remove files ...
  • flameman: i need help to complete this table

memory map of the board will be added as soon as possible
