Several points (please read the whole email before doing anything else):

1_ It is not clear whether you still need/want to "avoid displaying" the menu 
border (i.e. make it transparent). You mentioned that you eventually managed to 
do so, but then you also ask (again) about vesamenu.c regarding the menu 
border. Or, perhaps... Do you actually, really, want to "delete" the menu 
border (i.e. the menu border would _really_ be "zero pixels")? If that's the 
case, that's not available as a directive in syslinux.cfg, so you would need to 
hack the source code (and most probably you would be on your own at that).

2_ Regarding the color of the boot command (starting from the boot menu), the 
same link you posted also mentions other elements, such as "menu color cmdmark" 
and "menu color cmdline".

3_ Unless you specifically want to use a Syslinux variant (e.g. ISOLINUX), I 
would suggest not investing "too much" time on configuring it. In the near 
future, most Linux distributions won't be using it.

4_ If you still want to invest time on it, please carefully read the available 
documents, as most common answers are already there (e.g. "menu color 
cmdline").

5_ Please, avoid posting the same emails twice (relevant for any participant).

6_ When replying, please use the Syslinux Mailing List public email address, 
unless there is a specific reason not to do so (relevant for any participant).

7_ Please avoid top-posting; it is confusing, and annoying (relevant for any 
participant).

Regards,
Ady.
