ML150 G2 BIOS setting

[ThomVis]

We have a ML150 G2 we want to use in our office. The system is quiet enough, except for the rear system fan. It's not failed but a bit out of balance, so it resonates. I've tried to replace this fan with a real quiet one, but then the system nags there is no fan connected (there is and even at 1500RPM). I would like to disable monitoring of this fan.
The Monitor screen in the Setup Menu (BIOS) tells me:
"All items on this menu cannot be modified in current mode"
This indicates there is a mode in which you can modify these settings. I've tried the old [Ctrl]+[A], no luck. Can anyone hint me on the magic key combination towards a quiet system?

good place to start

That is where I started. The "HP ProLiant ML150 Generation 2 Server Maintenance and Service Guide" tells me:
"This menu displays the data of the system monitoring. The items in this menu cannot be
modified in the User mode. Consult the system supervisor if any changes are required."
Well, I am the system supervisor. I am in supervisor mode, not user mode when browsing the BIOS, but I still get:
"All items on this menu cannot be modified in current mode"
on the Monitor screen.

have you tried maintenance switch on sys board..??

[ThomVis]

Newest BIOS is installed (2006.06.30, 1.57).

The "HP ProLiant ML150 Generation 2 Server Maintenance and Service Guide" remains very quiet about a maintenance switch. Can you point me to documentation about that?

There are two unidentified jumpers on the motherboard. A 2 pin jumper labeled J32 and a 3 pin jumper labeled J33. But without documentation I am not going to short those.

Ah, the infamous Clear CMOS jumper.
If left in the Normal position is gives the situation as described. If I leave the jumper off, it's the same. If I put the jumper in Clear CMOS position, the system won't boot (gives 3-3-1 beeps iirc). BIOS is reset though, but still situation as described.
I've tried clearing the CMOS with the fan not attached, but at POST the system still nags the fan isn't there.

[marcus1234]

hmm you state when i replace the fan the system complains there is no fan there


how many pins does the old fan connect to are there cables betwen fan and connection


and new fan how many cables and pins does that have

if both have say 3 the wiring can be incompatible so on the new fan cable juggle wires around
and the new fan tried was it same spare part number//

[ThomVis]

The replacement fan it an off-the-shelf silent one. So no part#.
Both fans have a 3 wire connector wired the same way (plus, minus and sensor). Teh replacement fan spins the way it supposed to, but the system won't detect it. I just want the system to stop looking for it.

[marcus1234]

hmm... so we are down to the common issue...

evidently the new fan is missing some logic as it does not let the system know it is installed i suggest get the orig fan and see what happens appears its circuits somewhere along the lines have logic, or the new fan is being connected incorrectly,

[ThomVis]

With all due respect, maybe down to the common issue, but away from the original question.
I'm not interested in fiddling with fan logic circuits. I want to disable the system looking for the fan altogether, which is suggested with the "current mode" message in the BIOS.

[marcus1234]

ok if we find nothing in the user guide it is down to moving jumpers on the board and looking at what may seem appropiate on the panel that is removed it may give vauge hints..
hopefully it does ,

and failing this then looks like plan b to get the orig fan..

[ThomVis]

Descriptions on the panel does not mention the jumpers.
So there is no HP engineer who can tell me how to disable the monitoring of the rear system fan? Or confirm this is not a setting in the BIOS?

[Johan Guldmyr]

Went through an old BIOS simulator (doesn't say what year it's from) for the ML150 G2 and there appears to be no settings regarding the fan speed.

Would it perhaps be possible to disconnect the sensor wire? Maybe that would get the fan spinning but trick the system to think it's not installed/does not need monitoring? (never tried this myself).

[ThomVis]

Trick the system to think the fan is not installed won't do it, the systems detects this and warns it's missing (and won't boot when rebooted remote).
I've tried running the fan with sensor wire detached. It's runs, but monitoring still kicks in.

ThomVis --

Under the "Advanced" section of the ML150 G2 BIOS setup, you should see an option to enable/disable the "F1 Continue Prompt". If you DISABLE this, the system should then boot without pausing (i.e., without prompting you to press F1 to continue) upon detecting what it thinks is a disconnected or non-functional rear fan.

Hope this helps,

Does ML 150 G3 have "Advanced" feature in BIOS? I can't see it

[Erdogan Temur]

Hi Baf,

ml150 g3 bios update. pls.

http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&prodTypeId=0&prodSeriesId=1163831&prodNameId=3279687&swEnvOID=1005&swLang=8&mode=2&taskId=135&swItem=MTX-18d6831babf94294b894eab436

[Baf]

Heh...
It's not as simple as you think :)
Post screen says that I have "Compaq System ROM 2005.03.10" BIOS rev.
But here http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&prodTypeId=0&prodSeriesId=1163831&swItem=MTX-18d6831babf94294b894eab436&prodNameId=3279687&swEnvOID=1005&swLang=8&taskId=135&mode=5 I see that initial relise of the BIOS is 2006.04.29
And when I'm trying to flash BIOS from usb flash drive with latest revision it says that there are no components to update.
When I'm trying to flash with oldest one from floppy it says that can't load DOS or smth that...
What I need to do?
Does the latest ROM have 100% have this advanced menu?
