Last log says: localhost syslogd[293]: Fatal error, exiting I could enable syslogd verbose option as a last resort; but not sure about when it would trigger next, hence would preferably like to avoid keeping verbose enabled. Are there any other known issues why syslogd would exit? Mayuresh

Yes you would lose access to the raid sets managed by the card and would have to use raidframe and software raid to get the raid behaviour back which would involve reconstructing the filesystems from scratch. If you are getting a second card it might be easier to just use that for the tape drive and leave the existing working card alone. I also seem to recall that there was a way to unbrick a card if something goes wrong but my memory could be faulty. Its easy to be blase about this sort of thing when the cards you are potentially bricking can be fixed by your client if something goes wrong. Does LSI provide official images or is it a question of someone grabbing firmware images of another card that just happens to work? Last time I looked (which was about 12 months ago) LSI did offer firmwre downloads from their website. Its entirely possible that a newer raid firmware might allow passthrough of the tape drive so that's also worth considering as well. Ultimately with the LSI cards device discovery is entirely in the hands of the card firmware (which it then passes to the OS). Mike
Re: playing with bootxx_ext2fs

I can try to take bits from bootxx_ext2fs and push it on the right places onto the ext2 file-system with dd if/skip of/seek. I am going out on a limb here, but what installboot does is (1) install bootxx_*fs as PBR (mbr partition boot record), and (2) patch the location (sector offset, presumably?) of /boot into the PBR code. I would think this is fs agnostic?

Re: MULTIBOOT fails w/ GRUB2 and SYS/EXTLINUX
Correct. But does that matter? IIRC, only the Xen Dom0 kernel is multiboot-compliant, and even then, it is a multiboot _module_ to be loaded after the Xen kernel. But I could be wrong.

Re: MULTIBOOT fails w/ GRUB2 and SYS/EXTLINUX
I think that GRUB2 has a special module and command to load NetBSD kernels:
knetbsd /netbsd root=/dev/wd0e

MULTIBOOT fails w/ GRUB2 and SYS/EXTLINUX
Yolo again
this message closely relates to my two previous ones -- on bootstrapping netbsd
from an ext2fs manually -- and I am now and finally considering MULTIBOOT.
Although I have seen some success reports with GRUB2 *1, all I get is failures.
With GRUB2/multiboot and multiboot2 I get
error: no multiboot header found.
The GRUB2 configurations I tried:
menuentry 'multiboot netbsd' {
insmod ext2
set root='(hd0,msdos1)'
multiboot /netbsd root=/dev/wd0e
}
menuentry 'multiboot2 netbsd' {
insmod ext2
insmod multiboot2
set root='(hd0,msdos1)'
multiboot2 /netbsd root=/dev/wd0e
}
Although it is supposedly the default now, I even tried with a custom kernel
(`options MULTIBOOT`).
Note GRUB2 offers some tweaks to workaround things *1. No change there either.
Now with SYS/EXTLINUX, I get something similar
Invalid Multiboot image: neither ELF header nor a.out kludge found
How get the boot strapping process to load the netbsd kernel fine using
multiboot?
I remember I was able to load XEN+NetBSD with the GRUB `kernel` and `module`
parameters before, and I believe this was doing MULTIBOOT already. But maybe
that was GRUB legacy.
