Re: [gentoo-sparc] Booting the system...

[BRM <bm_witness@yahoo.com>]

I already have the firmware on initrd - pulled from /lib/firmware on the main disk, which was built using the mentioned qlogic firmware package.
So, I'm guessing I'm just missing the udev stuff then...hmm....

Quick question - how does mdev and udev differ? It seems to be running mdev, which something I came across mentioned that it is a udev replacement seemingly for initrd images. Any how...

how do they differ?

And could I just pull the udev files from the main disk to do the work?

I really hope I can get this working sometime on Friday - that's my last day for being able to get this system working.

TIA,

Ben

P.S. Sorry, I would have replied in-line, but the new Yahoo! interface is a real pain for replies.

Ben,

you're almost there.  Get the binary firmware from 
ftp://ftp.qlogic.com/outgoing/linux/firmware (just get the .bin files, not 
the .bin-version files).  There are five or six files altogether.  You don't 
need all, but they are relatively small so it's no big deal putting all of 
them in /lib/firmware.

Make sure on the initramfs you have /etc/udev/rules.d/ with appropriate rules, 
including one to handle firmware loading.  Also make sure you have on the 
initramfs /lib/udev/firmware.sh.  This script is part of udev.  Just copy it.

Then recreate the cpio.gz and try again.  My guess is you forgot to include 
the actual firmware.  But you're getting very close to a working system :-)

Oh and last but far from least, you need a working /init script on the 
initramfs.  All it needs to do is mount /proc, /sys, /dev as a tmpfs, start 
udev, mount the actual rootfs device (as per your silo.conf) and switch_root.
