Just today I discovered which are the proliant models that work with similar mother boards . My troubles are related to a SE1102 Proliant on which I'm not able to slow down the fans. At this time I was able only to disconnect the inlet thermal sensor obtaining a constant 8000-10000 rpms for the 4 fans (depending on the CPU temperature). Before doing this as soon as the room temperature increased up to 24.5-25 °C, then the fans started increasing their speed going up to 14000 RPMs. Said that 8000-10000 rpms is better of 14000 rmps for my hears, I need to slowdown them more and more, I've read that someone have them running at 3000 rpms!!! I haven't LO100icard, I can only point to the server through the serial port and play some commands with BCM cli on a serial terminal (teraterm). I tried vSphere baremetal, Debian server plus HP-tools and every other ipmi utilities promising to let me controlling the bios and powerful setting in the hope to be able to find and set any kind of option fan related. But I get every time errors telling that the model is unsupported so Hponcfg, ipmi-tools, and so on don't work for me. I decided to upgrade the firmware with a new compatible bios so I searched for similar motherboards and found ML150 G5 at the first and then DL180 G5. I downloaded their bioses and tried to flash them without results, I get error of unsupported model. Yesterday night I tried to change switch setting obtaining an automated flash of new a new bios (I think it is stored somewhere into the board may be for emergency autorepair). Trying different combinations of the four switches, I found that all combinations load the O31 ROM ID BIOS, one combination (off, off, off, off) loads the O32 ROM ID BIOS, but the server coudn't startup telling about a FAN4 error and shooting down the machine in 6 seconds. My BCM ROM is flashed at the latest ROM found: the 3.20, but I'm not able to flash the DL180 BIOS because the server turnes off at this switches combination, and for the working ones the bios is incompatible for the ROMPAQ.EXE flash utility.
HOW did you upgraded the system BIOS please? ROMPAQ.EXE lacks the "FORCE" option :-( :-( :-(
I decompressed the ML150 G5 and DL180 G5 respective bioses and THEY ARE IDENTICAL, so the problem is to force ROMPAQ.EXE utility to flash the bios. I would like also to save the original O31 ROM ID BIOS, but I can't dump it with any utility or ROMPAQ.EXE or through serial connection (only flash but I don't know how to send the firmware to the serial port, because the CLI "load" command acceptes bios images from tftp sources only).
unfortunatelly you probably won't read this question, but may be that others users will read it and could aswer to me THANKS IN ADVANCE
