VIA Epia-MII CF question

Hi again!

Another point from http://www.coreboot.org/VIA_EPIA-MII
is the need to recreate the initrd.

When I install the system with Ubuntu's 2.6.24-22-generic kernel
and initrd, the installation environment recognizes the cf
as ata3.

There it works.

When I boot through FILO, using the below line, no such luck.

CONFIG_AUTOBOOT_FILE="hde1:/vmlinuz initrd=/initrd.img root=/dev/sdb1"

The wiki "lets me" either use the CF slot as standard ide or through
pcmcia-utils.

This standard-ide approach, as said, did not work.

Is the wiki wrong?

Can there be something wrong with FILO that would cause this
ata3 not found?

PS:

After ata1/ata2 detection, I get dropped into an initramfs shell,
missing the root device node.

I couldn't find anything about pcmcia-utils in the initrd, which would
screw the bus up.

I then created a modified initrd with yenta_socket and friends, and
pata_pcmcia didn't not get automatically installed.

On manual installation of everything that was involved in the installation,
like pata_pcmcia and whatever, nothing happened. (!)

Anything?

Thanks!

Did some Sherlocking around and it seems the wiki is outdated.
And slightly wrong.

The mentioned scripts there, mkcfinitrd and pcinitrd are
apparently for pcmcia-cs, because they use cardmgr, which
was apparently deprecated at kernel 2.6.13

http://www.kernel.org/pub/linux/utils/kernel/pcmcia/cardmgr-to-pcmciautils.h...

Also, the wiki says "the mkcfinitrd script is at the end of the howto",
which it is not, and was found only through Google at
http://tracker.coreboot.org/trac/coreboot/browser/trunk/coreboot-v2/document...

There's a HOWTO which is really helpful when doing pcmcia stuff for
the first time
http://www.kernel.org/pub/linux/utils/kernel/pcmcia/howto.html

and itwould be nice if the wiki reflected how this is relevant to
booting off the cf nowadays.

Also the parts about probing for ide don't seem to be true, no such
bootparam is needed here.

So here's what had to be done for this to work with Ubuntu, should
be pretty distro-generic even for non-debian-based systems:

### Extract initrd for work
root@install:/target/boot/initrd# zcat ../initrd.img-2.6.24-22-generic | cpio -i
32850 blocks

### Copy missing things over
root@install:/target/boot/initrd# cp /lib/modules/2.6.24-22-generic/kernel/drivers/pcmcia/yenta_socket.ko /lib/modules/2.6.24-22-generic/kernel/drivers/pcmcia/rsrc_nonstatic.ko lib/modules/2.6.24-22-generic/kernel/drivers/pcmcia/

### Copy udev file
root@install:/target/boot/initrd# cp /etc/udev/rules.d/85-pcmcia.rules etc/udev/rules.d/

### Copy helpers
root@install:/target/boot/initrd# cp /lib/udev/pcmcia-socket-startup /lib/udev/pcmcia-check-broken-cis lib/udev/

### Copy libsysfs so we can execute
root@install:/target/boot/initrd# cp -p /lib/libsysfs.so.2* lib/

### Copy options
root@install:/target/boot/initrd# mkdir etc/pcmcia
root@install:/target/boot/initrd# cp /etc/pcmcia/config.opts etc/pcmcia/

### Create initrd
root@install:/target/boot/initrd# find . | cpio -H newc -o > ../initrd.img-2.6.24-22-generic.mjt.cpio
root@install:/target/boot/initrd# cd ..
root@install:/target/boot# gzip initrd.img-2.6.24-22-generic.mjt.cpio
root@install:/target/boot# cd ..
root@install:/target# ln -sf boot/initrd.img-2.6.24-22-generic.mjt.cpio.gz initrd.img

Thanks!

If you have a little time, please contact Ron Minnich or Stefan Reinauer
about getting a wiki account and update the wiki page(s).

Thanks,
