Im trying to use newer simple-menu features,
and have found that the following config-file
(closely based on wiki pxelinux example)
- fails for 3.62-pre11,
- works for 3.62-pre10
where 'working' is successive reloads such that re-edits of file are
seen on next reload
and broken is issuing this error:
Initial menu has no LABEL entries!
boot:
#> more default
SERIAL 0 115200
CONSOLE 0

menu title PXE Wiki Boot Menu example

MENU AUTOBOOT Starting Local System in # seconds
label selfload
menu label ^Main, self-reload
menu default

KERNEL menu.c32

And while Im writing, Ive also had some mixed success with the c32 sample tools:
MENU TITLE c32 Tools

KERNEL hdt.c32
LABEL B hello.c32

1st, the working ones (output pasted from 3.62-pre1) :

boot:
if you wait ~20 sec, or hit return again, then reload happens automatically.
hello.c32
pcitest.c32 - does nothing, just hangs
hdt.c32 - writes a broken table-looking-thing to screen, then blanks it.
I suspect that the "console 0" may be part of the problem; I need this
cuz my soekris does some console/vga mixing that doubles characters on-screen.

by starting my picocom session inside a `script` session, I
got a better look at the output

I cannot tell how to navigate the menus,
but Im happy to repeat this script-based capture,
and do some blind menu-browsing to stimulate
more output. I'll look on your hdt website for clues (rummages..)
Id be inclined to refine the Wiki example (esp adding the
c32tools.menu file) once I can ascertain what exactly is wrong with
what Ive done.
