I'm new to these forums and I'm not sure if this is the appropriate place for suggestions / requests but it seemed like the best place to me.
I have the latest version of Kon-Boot working just fine with the following entries (which I added to "Others"):
title Kon-Boot V1.1
map --mem /ubcd/images/konboot.img.gz (fd0)
map (hd1) (hd0)
map (hd0) (hd1)
MENU LABEL Kon-Boot V1.1
The konboot.img.gz file is only 9.32KB, so it shouldn't be too much to add as far as the size of UBCD is concerned.
