Hi,

I can't speak to the oversize ISO, but I'm sure someone smarter than me is
looking into that.

Regarding graphics. IMHO, that problem is somewhat self-propagated by the
PPC community in general downloading
Xorg.conf workarounds or disabling drivers instead of letting developers
know that PPC users exist and care by filing and following up
on bug reports.

For creating the bootable USB, I always do it from within Linux and don't
use the hdiutil stuff.
**CAUTION** dd will overwrite/destroy anything after the "of=" and it won't
ask if you are sure first.
Make sure you are writing to your USB stick.
1. sudo fdisk -l and note the location of your USB stick. Will be something
like /dev/sdb (or /dev/sdc, etc.)
2. sudo dd if=/Downloads/Whatever/nameofyourdownloaded.iso of=/dev/sdb
bs=1M; sync
Where if=the path to your ISO download and of= the path to your USB stick.

**The following is specific to PPC.

Booting. I've never tried a G4 and haven't succeeded on G5 yet. I'll try a
better detail later, but for now this is on a G3:
(Note: early G3's that do NOT have a firewire port generally do not support
USB boot either.)
1. Hold <command><option><o><f> at power on.
2. without quotes "dev / ls" and enter
3. You are looking at a tree view of the path. Note that anything indented
will have a "parent" above it. In other words,
to get the whole path you have to look at the lines above.
4. Verify you can "see" inside the disk using dir and the path you noted.
Example: /pci@f2000000/usb@19/disk@1:2,\
5. Once you see a directory listing, Just change it to "boot
/pci@f2000000/usb@19/disk@1:2,\\yaboot" where the path matches yours.

You can also type "devalias" to get a list of short names and use those
instead. The PPC FAQ has more on that.

Alternate method for booting oversize ISO's if you have more than one
FireWire equipped Mac and one has DVD/SuperDrive. 
You can use that Mac as an external DVD drive. "Backwards Target Mode"
1. Put your burned DVD/DVD-RW in the MAC with DVD drive.
2. Put it in "Target Mode" by holding down "t" at power on.
3. Connect FireWire cable between that Mac and the one you are installing
to.
4. Boot this second Mac holding the alt key. You should see the DVD in the
other Mac as a boot option. 
5. Select it and click the right arrow.
*Note. The installer will see the hard drives in BOTH Mac's. Make sure you
pick the correct one to install on.
*Never install Linux TO a target, but only FROM. Unlike OSX, it is important
the installer detects hardware on the machine it will be booting from.
I've only tested this using a first gen G5 as the "external target mode
drive" installing to a G3.

Hope that helps.

Subject: [Lubuntu-qa] lubuntu/daily/ size larger than stated

 raring-alternate-powerpc.iso         12-Apr-2013 16:39  719M  Alternate
install image for Mac (PowerPC) and IBM-PPC @Lubuntu 13.04 (Raring Ringtail)
Daily Build
Actual size = 754.2 M

I mention this because I have been 'testing' the ppc images when I can. My
G3 iBook has a dvd drive that now only reads cds? and G4 is cd only so I was
hoping 719M would fit on my largest cdrw: it can 711M. If anyone in the ppc
world knows how to circumvent the ppc USB boot problem and has time to write
a short primer for me, I'll post it (credited) on my ppc Lubuntu wiki so its
recent googleable. I've looked and haven't found. My Intel Ubuntu GUI gets
ISO -> USB easy I believe, that step is well-documented but I can't get my
ppc to USB boot. Str8bs <str8bslinux@xxxxxxxxx> ? sounds like you were
booting ppc from USB? I've tried to copy ISO -> FireWire volume but the step
in which you start copying at/after the 63rd sector to cut out the cd mount
info? went over my head in hdiutil. I have 3 ppc with ATI cards, thinner
Lubuntu support every daily and no reverse-engineering skills to hack AMD
myself. If I had a ppc web browser I could download their driver but of
course then I wouldn't need it. Single User OS - cli only on the G4 with the
dvd drive when I tested April 8th raring-alternate-powerpc. No crash but no
web browser/GUI. Every new Linux kernel seems to have a new reason why
radeon doesn't work.
