Since I don't have a floppy drive, can I install GAG on a CD and boot off of that?
Excuse my poor english.
GAG is included in the Ultimate Boot CD. (http://ubcd.sourceforge.net/).
So you only have to download the ISO image (121 MB) (http://ubcd.sourceforge.net/download.html), burn it out, boot from it, and select GAG.
Of course besides it you'll have another util tools into the CD.
