Hi Jim,
I have cross posted to LINUX PPC mailling list because some of the things I
want to
say may interest others. Yesterday was a *very* good day as I finally got things
working.
The first things to say is that nothing would have been possible without the
help of
Cort, Gabriel, Alois, Corey, and Marc. I did very little compared to what
thoses
guys have done => congratulation and thanks to you all.

As the post is long you may go directly to <=========
1) LINUX works on MCP750 even without SCSI disks,
2) I hope I will manage to give something more presentable than the current
horrible kludge I did, back to the development of Linux on PCC.
3) I have ramdisk image, bootable things and so on but unfortunately <========
no public ftp site (company paranoid security rules). So If you want
something
mail me. If someone has an address to put things it is also possible,
4) I do not want to enter a distribution battle but I run debian 2.1 which is
already
a GNU libc 2.1 and available (once you know the ftp site)
5) I mailed the utils-linux maintainer and he will deliver a new
<=============
version (2.9f) of cfdisk that should support PPC this week or next week.
I will test it so if someone has patches that he wants to be included => mail
me...
I saw patch in SRPM form for 2.8.5b but was unable to get rpm working on it :(

I ported Chorus on MCP750 also and have patch available on demand...
Note I already reported this patch to Chorus so they should be able to
gave something more "supported" than what I did as I just did hack the
MVME2700 code...
Jim> PS. Did you work for Chorus?
7 years :)
