Hello,

I've installed Debian Squeeze on a new Supermicro server with X8DTU-F
mainboard. But Grub2 gives just a black screen. Only when I press the
arrow down key on the right moment and I wait a bit, I see Grub.

Somebody an idea what I could do to see Grub just the normal way?

With regards,
Paul.

We run a number of Supermicro servers with those boards in them with
Squeeze and have not had the issue

your describing and we have not changed grubs default install settings.

Does the board have IPMI installed? If so are the redirection settings
set correctly? Not that I can think of any

reason that it would affect grub from displaying.

Regards
Shane

Strange. This is the second board I have of this type with an invisable
grub. The problem was direct after installing.

With the first board I had some unreproduceable VGA problems so I
returned it. After the boot logo what was always shown correct, the
screen stayed sometimes blank. Even in the bios.

Yes, IPIMI is by default on the board.

Hmmm, good idea. I've tried to disable "redirection after bios post" and
to disable the complete remote access in the bios. But no success.

After enabling it both, I've used the IPMI "SOL activate" command to see
the booting process. It starts well, but after "BMC responding" and
sometimes "Checking NVRAM.." I don't see anything anymore. So no Grub
there too.

With reagards,
Paul.

I found what it is. The VGA card starts very slowly. When I change
GRUB_TIMEOUT in /etc/default/grub into "20" I see grub after 8 seconds.
The default is 5 seconds, so that's the reason I don't see grub.

In the other board what I've returned the starting time was slower, I
think now.

With regards,
Paul.

Ah, this gives what I want, no delay!

Thanks!

With regards,
Paul.
