O.K. I just verified it yesterday. And my TiPB does not boot with yaboot 1.1.1!
If I boot into yaboot I use a bootscript. On my Pismo I get a white
screen than the grey screen and than comes yaboots selection-screen.
Using the same yaboot on the TiPB I get the white screen than the grey
screen and than nothing. If I jump into OF and type "boot
hd,10:\\yaboot" I get a grey screen telling me "Loading ELF" and after
some seconds jumping back to OF-prompt with two lines of "ff ff ff
000000 [....]" or some such (If this is important I will test it this
afternoon and write it down)

Have to look for it in the afternoon. But look at my other mails I told
Timothy that this is not just a wrong reported connection speed, I need
20-30 minutes to copy the 2.4.2-kernel-source form the Pismo to the TiPB
both running linux.

I will try to reproduce it, but at the moment I´m thinking this is a
problem of mol and MacOS 9.1, haven´t had any PANICS in the last two
days. I concentrat on getting linux and X in wide-screen mode, than I
look at mol.

That what I expected, I thought "Hey it is just a Pismo with a G4 and a
wider display, lets put linux on it..." and the trouble began :-(
I had heavy mail-traffic with Timothy, I´ve done everything he done and
I don´t get a wide-screen X in 32bit.
I´m running XFree 4.0.99 and the kernel from the titanium directory at
the ftp site, I only get the widescreen with video=ofonly but than I can
not run X and mol. Used the XF86Config from the ftp-site.
Every other video option leads to a 1024x768 resolution, even using
fbset -g 1152 768 1152 768 32 does not help, the terminal and X stay at
1024x768. I tried video=aty128fb:1152x768 and got a nice visual effect,
looks like the display is loosing all its colour. Do not know if this
could damage the display.

O.K. I will put it as cc to this mail. Just an idea, could it be that
the TiPB in the US and in Europe are a little bit different? This is
only an idea, because of my problems and the "no problems" of Timothy.
Thanks for your Help,
Christoph
P.S. I´m writing this mail with Netscape in mol running without a
problem on my pismo :-)
