Joseph, thanks for the help. So this is kind of our BIOS then! Cool!

Hi Chris,
the Bootloader firmware is stored in ROM--that is, it is built into the
system itself.
The other options include (which is not availible) changing boot order,
performing RAM test and so forth.
Cheers,
Joseph

Ah I see Joseph. I have actually got your podcast and I did hear
the bit
about the boot loader, but I believe you had an SD card at the
time so you
could show us how to update the boot loader. So if you're saying
we can load
the boot loader without an SD card loaded, what other options do
we have?
I'm quite curious now. Thanks in advance.

Hi Chris,
No, it does not require an SD card. The purpose of this feature
is to
find out what's actually going "underneath" in KeySoft (so to
speak). It
is useful for those of us who want to find out about what's
behind
KeySoft's operation and for troubleshooting purposes. If you've
listened
to my podcast number 5, you would have taken a "virtual tour" of
Bootloader.
Cheers,
Joseph

Joseph, won't we need something like an SD card for this
procedure, or is
the boot loader actually built in to the unit? I wouldn't want to
try this
out in case I mess up the boot loader, especially if I don't have
an SD card
with upgrade files on it. Also, I don't have a serial port on my
laptop so
couldn't try it anyway, but was just curious. Thanks for the
useful
information, greatly appreciated.

Hi list,
I've found this while playing around in Bootloader: there's
actually a way
to view debug info, as well as what's really happening in
KeySoft on a
computer screen. This is part of Debug--a way of debugging a
software or
hardware.
You'll need:
* A BrailleNote or VoiceNote (preferably mPower)
* A computer with HyperTerminal
* Serial cable (the one supplied with the BrailleNote; any RS232
cable
with female plugs at the ends will work)
Procedure:
1. On your computer, start HyperTerminal.
When the screen is displayed: if it says "Default Telnet
program," say
"no." If it asks you for location, press ESC, then say "yes" at
the dialog
that appears.
2. At the Serial (Com) port properties window, select baud rate
of
115200, no parity, 8 data bits, 1 stop bit and hardware
handshaking.
Press ENTER. It is ready to go.
2. Phepare your BrailleNote
At this point, connect the serial cable to your computer and on
your
BrailleNote. On your BrailleNote, press Reset with dots 4-6
(jl). A
message will appear on your screen saying, "Loading config
data... .was
You've successfully prepared your BrailleNote. Then press c
(dots 1-4) to
start Debug mode. You should hear two rising tones, followed by
the
bootloader tone. Then press Reset button and some kind of
messages
(mixture of hxadecimal numbers like 0x001ccff or similar and
other bits of
"useful info") will appear.
3. If you want to end it
On your BrailleNote, go back to Bootloader by pressing Reset
with dots 4-6
(jl). Then press c (dots 1-4) to turn off Debug mode and press
Reset
button. On your computer, press Alt plus Fbled to close
HyperTerm. If it
sawith something about disconnection, poess y to say "yes." You
are done.
In addition to debugging, the Debug mode is preety useful to
find out at
KeySoft is actually doing (for example, if a card is inserted,
a
notification will be generated; similarly, if you choose to send
and
receive email, it will dispbay what kind of protocol is being
used,
connection messages and so forth).
Hope this info helps. Perhaps I might add this as an idea for
BrailleNote
Bootloader podcast.
Cheers,
Joseph P.S. If you upgrade KeySoft while Debug is on, it will
tell you
what is actually going on when "loading," "erasing," and
"writing" message
is displayed on the braille display (if you have one).
