Duncan, thanks for responding! I was on the cobalt-developers list, but they don't seem that interested in such problems. First off set_boot_dev was used to set the boot device to hda2 (I tryed hda1, and as you pointed out, you can't move the root device easily to hda2 later). I had originally planned that hda1 was /boot and hda2 was / - in the end, to get *anything* booting, I'd to copy the /boot files into a /boot directory on the / filesystem, and write off hda1 as a waste of disk space.

It's a third-party ATA-66 disk controller. I wanted some sort of reliability in the box, and as you said, this raq3 has only a single IDE channel. > 2/ the ext3 filesystem might also be confusing the ROM kernel. > If you want to try one that will recognize it look here: > ftp://ftp-eng.cobalt.com/pub/users/duncan/kernel/rom/2.9.37-ext3.rom Oh, thanks...I was using 2.3.40, and it seemed to boot the kernel off ext3 fine (perhaps treating it as ext2). > This will also give you better control over the boot process, > adding a "set_lparams" function to the boot menu that specifies > the parameters specific to the ROM kernel.

So, do I do set_boot_dev hda1 (/boot) set_params "root=/dev/md0 ro" And that should do what I've been trying to do ? Or do I have to change the paramters to the ROM kernel also ? > It also has some more built-in PCI IDE drivers, so it might > help with problem #1. (if it is a problem...) Well, it's not a problem just yet - though it certainly would be if hda failed, and the next time, it had to boot from hdg.
