I enabled the busybox option and used the default value of "5 second pause to allow access to busybox" but it doesn't pause anywhere, as far as I can tell. Coreboot starts, LAB starts, LAB kexecs the kernel/initrd on the SATA disk, and then at that busybox prompt, I get no output when I issue "fdisk -l /dev/sda".
So your kernel/initrd is busybox-based as well? Is the new kernel really getting run?
I'd start with ls -l /dev/sda or something simple like that.
Could you send me a tarball of your buildrom-devel?
Since it's old I don't think that would be really helpful. Are you changing the .config files? Are you changing the skeleton/ files?
Something must be different in our config. Also your lab.conf and the kernel/initrd that is on your SATA disk, if that would ok.
I don't have that machine up right now, so it would take a while. I think there's a shorter path to the answer than that.
I built my own static kexec and xfer'd it to the SATA drive.
Great.
Multiple drives shouldn't make any difference -- if the controller can see one drive, it can see them all (if it is actually working properly).
You're right. If they don't all work it's a bug. Maybe it's been fixed. If you're only using two drives, though, it's probably not that.
My system may have 2 drives or 8, depending on its function. The one I'm currently experimenting
with has only 2 installed.

So far it's just me seeing that, on one specific board

don't worry about that too much just yet.
True, I'll cross that bridge when I get there.
First I'll need to be able to boot, period. So far, what
I've done is
this:
- Subversion checkout of latest buildrom 2. make menuconfig,
specifying Tyan S2892, 32-bit LAB 3. make
Do I need to do further configuration (Config.lb etc)? I
thought that
the menuconfig took care of everything. Maybe that was wishful thinking..
It's not. The only other thing you need to do is *pre*pend the vga image to the generated image, which will generate an image that is exactly 1024KB large, and which you can flash, and which *should* just boot your system.
I finally got coreboot+LAB to boot my target kernel/initrd on the SATA disks (many thanks to Ward)!
However, once the init script in the initrd attempts to assembly the software RAID, it fails because it can't see the SATA disks.
How many do you have? Ward has seen a problem with some disk controllers not functioning on the ck804. I've never used more than one.
My guess is that coreboot is originally doing some low level block reads from the disk to load the kernel/initrd but when the final kernel attempts to do a SATA read from the disk, the controller has not been fully/properly initialized, and it fails.
Have you tried configure the busybox shell to not load automatically, and looked at the SATA drives from there?
I assume that whatever modifications that Myles made to successfully
boot from SATA devices with coreboot+LAB on S2892 have trickled down to buildrom..
I used buildrom. I think the multiple drives may be getting you, though.
Thanks, Myles
