[9fans] Plan 9 on Intel P45 chipset motherboard

["Wolfgang Kunz" <woku@hush.com>]

Hi,

after reading a lot of chip sets I was thinking:

No risk, no fun

and bought a very new motherboard. The board is
an Asus P5Q SE2 with Intel P45 and ICH10.

http://www.asus.com/product.aspx?P_ID=T4T7B10FfR6zJ4Ns&templete=2

Here my results:

1. The installation of Plan 9 is not possible. I found
that the Marvell 88se61xx IDE controller is not working.
The message:
pcirouting: ignoring south bridge PCI.0.31.0 8086/3A18

could give more information. However: Installation with an
normal IDE cdrom is not possible. I will buy a SATA cdrom
and try it again.

2. The AHCI-driver works fine and Plan 9 runs like a storm.
I have the SATA drive attached to a Sil 3114 controller and
put both in an old PIII maschine. Booting and installation
of Plan 9 is slow but works fine. After that I connected the
drive back to the Asus board and changed the bios settings to
AHCI. Then I crossed the fingers and booted. It worked! I am
very happy! Now I have a very new fast motherboard with a
running Plan 9.

I use a nvidia 6200TC videocard. Here I have a problem with
the monitor setting. My Acer TTF need 1440 x 900. I changed
the plan9.ini to e198wfp as monitor and 1440x900x8 as vgasize.
Not a good idea. Now I can see anything.

Now my questions:

How can I stop starting rc and go to the console? Booting from
cdrom is not possible at the moment.

Any idea for the setting for my videocard/monitor?

Is it right that I can attach a SATA cdrom to the AHCI driver
and booting from cdrom works?

The ICH10 seems to works in AHCI mode. Are there some test that I
can make to verify this?

Wolfgang
