Hi, Demoman. Welcome to the Kindleboards. This is from tedsan's website:
"Individual font files are installed by placing a single of the the update_xxx.bin file into the top level directory of the Kindle 2 through a USB connection.
Note: download one of the new font .bin files (e.g. update_arialRndNrw_install.bin) from the website and save it somewhere on your computer. Each .bin file represents one new font. Connect your Kindle 2 to your computer with the USB cable. Open Windows Explorer. Your Kindle will appear as a drive in the file listing. Drag the saved .bin file to the drive letter that represents your Kindle. (Don't put it in any of the subfolders on the Kindle, only in the 'root directory', the main drive - on my PC it is called Drive (F
Kindle.) Dismount your Kindle from the computer using the "safely remove hardware" choice in your toolbar.
The Kindle 2 is then to be updated to install the new fonts. This is done as follows:
Note: these steps are self explanatory
From the "home" screen, press "menu"
Select "settings"
Press "menu"
Select "Update Your Kindle"
The Kindle will go through the installation procedure and restart itself.
Don't use the slider or the menu 'restart option' to do this. This causes an infinite reboot cycle. Just let the Kindle do its thing when you go through the update process. I've done this hundreds of times now without a single glitch."
I've detailed the instructions in my notes (in blue) above. Remember, this font is only for use on the Kindle 2.
After you do this you should have the new font on your Kindle 2.
You can try other fonts by repeating the procedure above with a different font .bin file. You don't have to uninstall the last font in order to do this.
To uninstall the hack completely and return to Amazon's default font, repeat the procedure above using the 'update_uninstall.bin' file instead of one of the new font .bin files.
I hope I've made this clear. Have fun and enjoy the results of Ted's hard work!
