If this is not a productive system, just try it and keep the original BIOS at hand in case you run into troubles.

The title says everything.
I know that it could be difficult to flash the HP board with programs (let me know if I am wrong), but I can force flash with a programmer.

The layout of the CUR-DLS non OEM is a little different, pin for front panel are different and in different location. Plus it has different RAM compatibility.
Should I be concerned?

Unless there's some specific problem you're sure an Asus BIOS cross-flash would fix, I wouldn't bother. The HP OEM board already supports both the max official cpu & memory it was designed for (2 x 1GHz Coppermines & 4GB of PC133 ECC SDRAM). If you're not already on it, you can get the latest HP BIOS (english version) from the Vogons Driver Library - https://www.vogonsdrivers.com/getfile.php?fil … menustate=30,29

If you need a different language version you can get it direct from the HP ftp server - ftp://ftp.hp.com/pub/servers/software/

The layout differences are minor - the front panel is just a simplified version of the standard 2 x 10 pin block...in the HP case it's a 1 x 6 (or 7) pin strip for Power On/Off/Sleep Switch, On/Off/Sleep LED & Drive Active LED. As for the RAM compatibility, although the HP documents state a max of 2GB (4 x 512MB) the board does support 4GB (4 x 1GB), although like most boards you'll only see between 3.25 & 3.5GB at POST. Both the ASUS & HP versions still only support ECC memory.

I was in a similar situation with another OEM version of the CUR-DLS, though mine was from a Fujitsu-Siemens PRIMERGY B210 server, but although I updated the BIOS when I got it I just used the latest OEM version from them with no issues and with the same hardware support.

Thanks for the reply.
Actually apart from compatibility issues and the front panel connection (where is the reset switch???), I was hoping to see an option to change the FSB (at least two possibilities, 100 and 133).
Is there a way to do so?
Modding a bios to that extent is far away fro lm my expertise.

HP FTP server is down now? It was still up last year I remember.

ETA: OK working now; don't know why it wasn't earlier.

In your case the HP OEM board doesn't have a reset switch pinout (it's from a server after all !!) - not sure if you can still trigger a reset by shorting the two solder pads on the full 2 x 10 block (pic below) - if so you could maybe solder in a suitable pin header.

As far as the FSB is concerned, I believe there are two versions of this board (whether ASUS retail or OEM) - one has a blue switch block near the memory (may be slikscreened as CLKSW) for manual setting and the other version has no need for this switch block as it's auto-setting depending on the FSB of the installed processor(s), remembering that you'll need 133MHz memory for 133MHz processors or 100MHz-capable memory (100 / 133MHz) for 100MHz processors. My board is the auto-setting type so maybe yours is as well.

It was up earlier today on the above link - probably down for maintenance (they have multiple mirrored ftp servers anyway)

Thanks,
Actually I wanted to overclock 100Mhz CPUs to 133mhz.
Got a pair of SL5QV able to work at 1330mhz.
