newbie
by Douglas Frank
Greetings all,
I've just subscribed. I've been googling around for quite a while now,
looking for an interesting project that isn't already almost done, and
that isn't essentially closed to significant contributions from people
outside whatever organization sponsors the project. That leaves out a
lot of otherwise interesting projects-- such as the kernel trace work at
opersys.com, or Fedora, or the crash-dump project (lkcd) just for a few
examples.
I confess I'm not just interested in "open source" for any altruistic
reason-- I'm really looking for a way to establish credentials in the OS
"community" (a much-overused word). I bet such be will be increasingly
important in future years.
A little context: I'm using Fedora (FC3) here at work (nobody seems to
mind that I can't read half of HP's internal web pages, which mostly
only work right with IE; and I *certainly* don't mind! :-) I naturally
poked around Redhat's site looking for Fedora work, but all they really
offer is a bugzilla listing. 98% of reported FC bugs are either with
badly outdated releases, or expansion hardware I don't have.
However there *does* seem to be an issue with FC3 and the 2.6.11
kernel-- with several reports of solid system hangs/lockups, where the
computer essentially freezes in place. Now on an Alpha, all you'd have
to do is hit the halt button, type "cra" at the ">>>" prompt, and
reboot; once in multiuser you'll have a crash dump waiting for your
debugging pleasure. But I've never seen the PC that had a halt button
that didn't instantly put you in POST, which kinda limits the chances of
copying memory to the swap partition. So at least on the PC
architecture, there doesn't seem to be a reliable way to do a postmortem
on a wedged kernel.
Obviously, the BIOS is a problem. Which leads me to you. What needs
doing?
thanks!

RE: [OpenBIOS] problem with strings
by shon＠soc-soft.com
Forth word "begin-package" takes three strings as input
begin-package ( arg-str arg-len reg-str reg-len dev-str dev-len -- )
With the current implementation, arg-str will be overwritten. So I think
number of pockets should be increased to three.
Regards,
Shon

The words reading strings from the interpreter into memory are using a
"pockets" implementation with two alternating string buffers. This means
if you want to put more than two strings on the stack without touching
them in between you need to create a copy of those strings.
Think of it as a temporary string buffer.
> Is this an intended behavior? Please verify the same.Q
It is indeed intended, since many forth engines do this the same way.
If it is not sufficient, you can raise the number of pockets in
forth/bootstrap/bootstrap.fs. Go look for:
\ pockets implementation for 7.3.4.1
If you have some reasonable sample code that needs more pockets rather
than becoming overly complex, we can raise the number of pockets in the
official tree.
Regards,
Stefan

problem with strings
by shon＠soc-soft.com
Hi
I have noticed an abnormal behavior in the string handling. Below is the
snapshot of the same.
0 > ok
0 > " hi" " hello" " bye" " welcome" ok
8 > .s <8> 4005810c 2 4005800c 5 4005810c 3 4005800c 7
ok
8 >
Above the strings " hi" and " bye" are stored at the same
address(0x4005810c) and also " hello" and " welcome" are stored at the
same address(0x4005800c).This means that the first two strings " hi" and
" hello" are overwritten and therefore lost. Strings defined using ' s"
' also show the same behavior.
Is this an intended behavior? Please verify the same.

Using OpenBios to boot Mac OS on CHRP?
by H S
Hello everyone,
I have an RS/6000 7025-F50. It is a CHRP machine from
late �98 and it has an awesome open firmware
implementation. It even has a great GUI for the usual
system configuration. The only thing it seems to be
missing is an xcoff-loader package. Thus I am unable
to load Apple�s Mac OS X bootloader, BootX. I
researched for a time the possibility of an elf
version of BootX, but it was beyond me and I could not
find anyone interested in helping me. There is not
much PowerPC development over at Open Darwin since
most people already using PowerPC machines are using
Macs, and Apple has already taken care of everything
for them.
Well I have been following the work with PearPC to
bring it OpenBios support, and I got to thinking would
it be possible to load OpenBios from my open firmware,
which then could load BootX? Something like Open
firmware --> OpenBios --> BootX. Plus, my Open
firmware has limited Mac-Parts and Mac-Files packages
similar to Old World Macs, so it can�t browse HFS+
partitions, which is necessary to locate BootX.
OpenBios could kill 2 birds with one stone; locate the
bootloader and load it.
Without kernel extensions for my hardware, I am not
sure how far along it would get. With RTAS maybe it
could boot in some sort of �safe mode� with minimal
support? Well, even if it kernel panics I would still
consider it a victory to see the grey Apple as BootX
loads.
You can find some information on the F50 at a little
site I made about it.

Hopefully this makes sense to someone!
Thanks,
Hanns
