Can you get to this page without a service contract?  You do have to log in.

http://h18004.www1.hp.com/products/servers/service_packs/en/index.html

There's a 2.5 GB bootable ISO that has all the updates for the entire Proliant 
line, basically, as well as the Bladeserver line.

While I still think it is easier to just download and boot on the DVD (which 
works for many models too), you can try:
  
http://h20565.www2.hp.com/portal/site/hpsc/public/psi/swdHome/?lang=en&cc=us&sp4ts.oid=3562405
and choose Red Hat instead of CentOS.
Then choose the "Obtain software" entries instead of the Download ones...

Hope this works out. :)

You could use a Windows 98 (or other Windows boot floppy) to boot and run
the flashing utility.  You can even boot up with your USB stick (has the
utilities) plugged in ( it should become C: ).

I'm sure you could find a Windows floppy image online or one of us would be
happy to send you a copy (it would be about the security/trust you can have
in freedos images anyways).

Once you have the image it's trivial to turn a floppy image into a bootable
ISO.  But it sounds as if you have floppies and a floppy drive.

I think the freedos bits I saw in the HP bios updating archive for my
system was for the "Crisis Recovery Disk".

Interesting. I need to look at them further.

HOWEVER: I saw something there about unpacking an .exe... and googled
that, and found someone talking about doing that... which led me to
cabextract, and, sure 'nough, I now have what was in that exe - flat
files, CD, floppy! even a WinDoze floppy label printer!

Now all I have to do is figure out which will be easiest to use - I'm
hoping I can just copy the flat files or the floppy files, or USB files,
and reboot into freedos and go.

Hirens has been around for quite a while, and gets updated 
periodically. its a all-in-one CD or USB boot full of mostly open 
source tools, can boot into memtest86, a linux kernel/shell/gui 
environment, or into a 'bartPE' mini-XP environment.  freedos too, I think.

hirens themselves only distributes the kit to build it, since it 
involves some licensed software, but pre-built ones are available from 
somewhat marginal sources (bit-torrent, etc).

you could, of course, simply use a plain BartPE boot, too, that you 
built yourself (Bart provides a toolkit for creating a winPE style 
environment).  you need access to a Windows desktop system somewhere to 
build one of these, along with the Windows XP CD to get the required files.

Never heard of it. Just looked at it... winPE - is that the miniXP?

And it bothers me that I've never heard of hirens - I *do* have to be
aware of security. I'm still thinking of wine.

The ISOSs are downloadable...
Google "firmware maintenance cd" and check the "version history" to get the 
latest one.
Then, try the "release notes" to see if you find your server model (not always 
listed).
If not, go back a few versions until you find it.

No such luck: we don't have such a maintenance CD; if anyone does, it's
the other Institute, and as we're doing admin work, I'd guess they don't
have a real admin, so who knows where it is.

But wait, it's worse than that, Jim I did, in fact, boot freedos from
the USB key this morning... and when I tried to run it, it announced that
it *can't* be run in DOS mode.

No, there's no way anyone's going to spring for a Windows license, install
it, do the update, and redo the system as CentOS.

Joking aside, do you, or does anyone, have an opinion on the advisability
of trying to flash the BIOS under wine?

You can boot from the Firmware Maintenance CD.
It will auto-detect all the hardware firmwares and update them if needed...
You just have to find the most recent CD that still supports your model 
(see in the release notes), since they gradually remove old hw to make

Replacing the first memory pair made the error messages go away.

Edac-util still segfaults though. But as the system seems to be otheriwse
stable, I probably will not investigate this further.

Or set up a PXE server with a freedos floppy image.  Use memdisk to load
the floppy image into memory. [0] [1]

I've uncompressed and loopback mounted a freedos image and then added bios
updating utilities my image(s).  Unmount and re-compress the image if you
like.  It is possible to boot a compressed (gzip only?) image via memdisk
for the record.

I think the "emergency boot cd" contains bootable freedos images...

was looking for a URL for it, and I find many things under that name,
but I'm not sure that any of them is the one I'm thinking of. I'll post

Hi, there Vipul, old buddy, old pal I've *got* an HP DL580 G5 that was

Hi Peter

One of my old HP DL585 had a similar issue but it turned out that the DIMM
slots were at fault. The server chassis had few led blinking red for those
DIMM slots and indicating that they are faulty. I removed the memory from
those slot and re-inserted them to the spare DIMM slots and everything is
working fine since then.

Thanks for your response and suggestions.

About identifying the faulty DIMM: Is the memtest provided on the CentOS5
installation disk best tool for this purpose? And do I need to switch ECC
off from BIOS while I test the memories?

The EDAC error msg reports problems with bank0. Can I trust this? I tried
installing edac-utils to get more information, but after installation it
only generates segmentation fault:

# edac-util --report=simple
Segmentation fault

# edac-util -s

fully agrees, however I had a situation once where these messages
appeared after a Kernel update. I learned that the kernel developers
added some extra error messages for my chip set with that update.
Booting an older kernel made the errors go away. OTOH, if the board is
already some years old, this is not very likely (and you will have to
replace the memory anyway.)
