[gentoo-ppc-dev] Gentoo on Old World Machine

[Dean Takemori]

Hello,

I would like to install Gentoo 1.4 onto an Old World machine (8600 w/G3
upgrade).  The machine is fully functional (in both OS9 and Yellowdog
linux).

Using BootX and the proper configuration (root=/dev/ram init=/linuxrc)
I can boot the computer into the Gentoo Live system, and log in as root.
However, once there, the partition and disk tools ( mac-fdisk and
mount) etc cannot find either of the two hard drives installed, since 
the
/dev/[hs]da entries don't exist.  When I try to make them, MAKEDEV
fails trying to move (for example) /dev/sda- to /dev/sda.

My guess is that the Gentoo 1.4 kernel does not have the necessary
Macintosh SCSI support built in.

So, my question is, do I have to recompile the boot kernel to include
Mac SCSI support in order to move along in the install or is there
something I'm missing/not loading/not configuring?  If so, must I also
create a new initrd also? Are there any other  gotchas down the line
for Old World machines?

PS.  I've noticed a thread about this in the forum, and it appears that
I do indeed need to use a different kernel or ISO image, but that it
was being worked on for a release as of several weeks ago.  Is there
a Live ISO up now that can handle these old machines?

Hi

It's not a matter of an iso for those machines, its the kernel on that
iso is broken for those boxes. No matter. easy fix. Just need to roll a
new kernel for oldworld machines to download and use instead of the one
on the iso.

(It's being built as we speak, but its que'd behind about 6 other builds
on my distcc cluster.)

In the interim you can download the module you need from my webspace at
htpp://dev.gentoo.org/~trance/oldworld/ you'll need to force load it due
to kernel version mismatch, but it does indeed work.

Sorry about the kernel on the iso, we goofed =)

Hi,

I did an install on the same machine as you did using the standard 
1.4rcX cd,
which actually ran like a charm. Although this has been quite a while, 
let me recollect
what i did.

- Copied the kernel and ramdisk image to a directory on my mac.
- Booted it using BootX (specifying the ramdisk image as / and make 
sure that
   ramdisk size is larger then 16Mb)
- got left on a command prompt, no harddisk, no cdroms
- insmod'ed mac53c94.o and mesh.o (located in /lib/mod... )
- executed the /linuxrc (or /rclinux), not sure no more), which failed 
miserably for
   some reason
- mounted the live-cd filesystem image on the cdrom, which requires you 
to insmod
   cloop (look in /linuxrc how its done and where it's mounted)
- chroot'ed to it, and continued my install

- recompile the kernel to support both adapters in the kernel, during 
install, and copy
   that kernel to your mac partition

My nitemare was a bit bigger seeing my harddisks where located on a 
aha2940, which
is totally not supported during install (kernel nor modules). Feel free 
to contact me for questions

Erwin

Dean,

I understand. In regards to a bootstrap iso, probably nothing specific
to Old World machines, since they can't directly boot off the CD,
however I hope to have a new .iso out which has a kernel that directly
supports Old World machines with SCSI. In the meantime yes I will put a
downloadable kernel which would work with the current shipping .iso's
for Old World users, and have a README-oldworld added to the mirrors as
well as an update on the ppc.gentoo.org webpage.
