EON on Zotac H55-ITX Motherboard

[Ian Daniel]

Hi,

I've managed to get EON installed to a USB flash drive on this motherboard and it boots ok. The only issue I have is that the /mnt filesystem doesn't auto mount. This may be down to some subtlety in the hardware as I had to deactivate 6 of the USB ports (it has 14) before it would boot.

Could someone point me at the mechanism used to mount the flash drive? I can mount it manually and update the config etc. But it would be nice if it all worked properly.

Hi,

Usually when this happens there is something the motherboard does not like about the usb key in the init phase.

You can test a couple of things

1 manual mount.
Mkdir /mnt/eon0
Mount /dev/dsk/c0t0d0s0 /mnt/eon0

2 Try to boot another machine with the key and see if it gets automounted.

If both of these work the reason given at top is definite. Hope that helps

Hi,

Thanks for that. Manual mount works absolutely fine ... I can update using that method if I have to. That key worked fine in previous hardware running EON so I doubt it is the key but I have another and will try it. It may actually be the motherboard as I had to disable 6 ports in the BIOS to enable EON to boot without hanging ... :-(

Where does this mount actually occur? Maybe I can debug it a bit more, I couldn't see anything once it had started that looked relevant.

Not saying something is wrong with the key, but more some incompatibilities with mobo boot and usb with this key.

Mount occurs same place as opensolaris in devices-local. To help with boot debug you can add -v -m verbose at grub menu.

Erm .. I think I found it ...

eon:40:/#fstyp /dev/dsk/c0t0d0s0
zfs

How did that happen? It has a UFS filesystem on it ....

/dev/dsk/c0t0d0s0 - /mnt ufs - no rw,intr,largefiles,logging,xattr,onerror=panic

That is a puzzler .. scratches head

I wiped it with dd and it's working better now. Dunno what happened there but thanks for the pointers as to where to look. It mounts ok on boot now.
