Any chance to look into the 1-wire LCD functions yet?

Hasn't been tested, yet. I have the board but haven't
wired it up.
The liveCD is too old to have support for the DS2408 versions.
I think the current order of fixes is
1. Simultaneous
2. directory speed
3. owperl and DS2408 writes
4. LCD
So probably a week or so.

I seem to be having similar
troubles too. I'm using a hobby-boards
driver on a 4x40 LC4857FG-SNYLV (which is essentially two 2x40 LCD's
put onto 1 board and I'm only using one of them ) It just gives me a
write error. Can anyone tell me exactly what that means? Is it
indicative of a wiring problem or a software bug? [See bottom for
OWServer's output]
1) I power on the LCD and all chars are dark boxes ( uninitialized
state)
I've then tried both
2a) Writing TEST to LCD_H/message
2b) I've also tried just clearing the screen
in both cases
3) No text shows on LCD. The top row of chars go blank and bottom row
stays same as uninitialized (full dark boxes).
I think my wiring is correct from what I can tell. Any thoughts? I'm
using the windows build 2.5p6b owserver binary. If I can get it
working, I'm going to try the liveCD and see if I get similar
results/issue.
