Hi have a variety of devices that I am trying to get to run ChromiumOS. They are as follows:

Device 1.
Processor: Intel Atom N280
Memory: 1GB DDR-3
Graphics: Intel GL40

Device 2.
Processor: AMD Sempron 2100+
Memory: 1GB DDR-2
Graphics: ATI Radeon X1250

Device 3.
Processor: VIA Eden CA22/P680
Memory: 1GB
Graphics: VIA S3

Device 4.
Processor: AMD Dual-core T56N
Memory: 2GB
Graphics: AMD Radeon HD 6320


None of the devices will boot. I do not see anything on the screen when they try. I know my build is ok, as I have tried it on my desktop and it boots into ChomiumOS fine, but on any of these devices I get nothing, not even an error. At frist I thought it was a known problem with the Radeon graphics card, but device 1 does not have that, it has an Intel card.

Any ideas of where I should be looking. I would REALLY like to get these devices running.

Anyone able to chime in on this?

The machine with radeon graphics might require more tweaking, as you said.  For the one with Intel graphics
try building the image with more kernel output. You can try passing this to build_image
--enable-serial=tty1
and see if you get anything on the screen during boot

before installing, had you tried running it on that exact machine from USB?

Yes, I am not trying to install it, but instead I want it to run from USB.

You might just go over all of the specs one more time and make sure you have the right build, is it x86 or 64? Is it ARM, AMD or intel?

If you triple check everything and it still doesn't work, it could just be that Chromium wont work with the hardware you have. But be sure to check everything closely.

Sorry it took so long to get back to you, but I tried adding the flag you mentioned but got nothing. I am running the dev build so should it not show kernel output by default anyway? It tried tty0 also, but that did not work.

what bootloader are you using, grub? You should be able to look at
the grub config files on partition 12 and see the kernel command lines
used. Can you double check if you have console=tty1 and loglevel=7 ?

Finally!!! I have the solution.

Sonny, you were quite right, we were editing the wrong file. We both knew that, but I could not find the right file. Where I failed was not reading the README file in the syslinux directory, which clearly states "Partition 12 contains the the active bootloader configuration when booting from a non-Chrome OS BIOS."

Doh!!!! So yeah, I mounted that partition and hey presto, there are my config files. Changed the /tempmount/syslinux/usb.A.cfg file to boot from root=/dev/sda3 and hey presto, it booted no problem.

Thank you for your help in fixing this issue. I would not have got there without you.

Peter

I just remember getting confused about which one got used in the past,
because it wasn't obvious for some reason but I can't remember the
details, which is why i was suggesting trying to change more
entries/files just to be sure that it's using the one you think it
is.. because evidence seems to say it's not using the one that you
think it should right now, doesn't it ?

Well grub is more advanced than syslinux, It can read more
filesystems, and I think syslinux probably cannot.  But you're right
that it's somewhat arbitrary, and one might just consider that to be a
bug.
