[LinuxBIOS] EPIA M-II (CF Boot)

[Carl Farrington]

I would like to add my name to the list of people who have suceeded with the 
EPIA-MII LinuxBIOS.

The VGA BIOS offset given by Nick Barker was no good for my board (Model: 
EPIA-Mii12000 LVDS), I had to use skip=786432 as suggested by Jun.

I am having problems with the kernel recognising the CF device as hde1 
though. I am able to manually mount hde1 from a diagnostics shell within the 
initrd after running cardmgr, so it is available, but once I exit the shell 
the kernel is saying it can't find hde1.

I'm not sure if Nick used devfs with his setup, but that's not available for 
my 2.6.14 kernel. I have used mknod to create the device, and also tried 
using udevstart but still have the same problem. I wonder if it's something 
to do with me having all the pcmcia stuff compiled directly into the kernel 
instead of as loadable modules? Unfortunately I'm quite rusty with Linux!

Anyway, I suppose this is a bit off topic. The LinuxBIOS seems to work 
great, thank you, and big thanks to Nick for all your work on the EPIA M2.

Oh, by the way, I used Award's AWDFLASH to flash linuxbios.bin. Using the 
undocumented /F option. Nick's HOWTO talked about a flash_and_burn utility 
which wasn't in the tree, and the flashrom tool just wouldn't compile for me 
for some reason. AWDFLASH worked, except for some strange quirks. I can't be 
certain if it was due to bad floppies on my part, but for some reason I felt 
I was having better success overwriting a good bios, rather than re-trying 
on a failed flash. The machine would go loopy sometimes. It all works now 
anyway.

cheers,
Carl

this is the second report of flashrom not compiling. Can you send in 
your error messages, and uname -a, and what distro this is?

This is very likely to be caused by th -Werror c flag.

Different gcc versions are pretty quick with warning about code.

Another reason might be that pciutils-devel is not installed.

I've added a note about this in the flashrom readme.

The error messages would indeed be very useful.

The error is something to do with the include of pci.h. I apologise if it's 
due to my system being broken. Here's the output of make:

No, your system is not broken, it just lacks libpci.a and it's headers. 
On Redhat and SUSE the packages you need to install are called pciutils
and pciutils-devel. I'd assume they have the same or a similar name on
Gentoo.

 Stefan

They do. emerge picutils and it'll work.

[Carl Farrington]

Thats great, thank you. I went hunting around my system for pci.h and found 
it in the kernel sources, and couldn't figure out why it wasn't working!

you're missing an include -- you need pci-devel.

[LinuxBIOS] maturing flashrom utility build

I have written the following small patch for the flashrom utility
Makefile. It will check for pciutils installation before compiling
anything and print an explicit error message if pciutils is not found.

This is much easier to parse than the half screen gcc errors.

Issue 40.

Commit?

yes please

I will get back on issue tracker I hope today and add a signed-off-by

Gooood! but you can run X? This is the key. And I can not yet.

I can't get past initrd yet! VFS: Unable to mount root hde1 or unknown-block 
(0,0).
It seems that even though I'm starting up cardmgr in the initrd, which 
sucessfully finds hde and hde1, upon finishing the initrd (closing the shell 
or end of linuxrc), the kernel doesn't find hde1. Could this be to do with 
my 2.6 kernel not having devfs. I have fired up udevstart though, although 
I'm not 100% sure what I'm doing, the device nodes are being created.

Or could it be that I need to upgrade to pcmciautils - the new pcmcia-stuff, 
as the kernel is warning me about use of depreciated ioctls with cardmgr.

ho hum. I haven't bothered playing on it tonight, as I've been staying up 
'til ~4:30am on this lately and that's bad for my work!

cheers!
Carl

How about checking these stuff?
  -- Dev node is created
  -- Root dev is properly assigned, path and (major, minor).
But, what you have to do now is gettting sleep.

Where did you get your initrd from?  Custom built or script generated?
 Functional root filesystems can be a bit tricky to get right.
