boot failure after dvd firmware upgrade hp pavilion

Hi,
I tried a firmware upgrade of my hp dvd burner, which stopped suddenly,
windows xp froze immediately. Unfortunately I cannot enter the bios now.
When I start my pc I get the hp event boot logo and then the system seems
to hang: the boot process won`t start. So it hangs in the early phase of
booting.........
Any ideas?
Thanks in advance
Martin

Unplug the burner and then try powering up/booting.

Proceed from there, if the system won't even post with the
burner connected then the burner is either trash or needs
tried on other systems to see if any can boot with it
connected, possibly allowing burner bios to be reflashed to
known good revision.

If when the burner is removed, system still won't POST, I'd
begin to wonder if the flasher was horribly buggy and
flashed the motherboard (or at least tried to, perhaps
erased a bit of it)... that doesn't seem likely but lacking
any other explaination for it...

Hi Kony,

You were right: with the dvd burner unplugged windows xp starts as usual.

Do I really have to remove the burner and try on another box?
Or is there any trick that a running win xp will detect the burner which is
plugged in afterwards?
As to now, I was unlucky in this respect.........
Thanks anyhow

Well at the very least you need to remove it from your case,
otherwise it won't be much good as a paperweight. ;-)

You can certainly try it, but I doubt hot-swaping in the
drive is going to work. Ideally what you'd do is boot with
another optical as the only device on that channel (set to
master of course) then swap cable to this dead drive, which
already had power. You could try adding or subtracting
other drives as master on same channel too.

Yep, optical drives are more problematic with regards to
flashing, because the EEPROM is almost always soldered to
the PCB, and few 3rd party tools deal with optical drive
flashing... but little good it would do if you can't get
system booted.


Something else to keep in mind is that it might be easier to
forget about windows and just focus on getting system to
boot to a dos floppy... towards that end, you might be able
to remove IDE channels from the boot choices and just have
it boot direct to floppy

If the problem is your dvd burner, disconnect it.
The Win XP should boot without problem.
Flashing firmware (drive) or bios (motherboard) are risky business.
If anything went wrong, it might render your devices unsable.

Maybe I will try this after my vacation........
Much easier would be a kind of hardware reset button ........

yes, indeed,I have linux running on my other computers. Only for playing
games and doing video editing I prefer windows, which at the moment offers
more software in this regard. But Linux is advancing here very fast......

No sorry, I even don`t own floppy disks any more.
Booting the system is no more any problem.
But thanks again
