Hi there,
I have Asus P4B533 with updated BIOS to 1015.

Sometimes i see that message at boot sequence and i use Windows 2000 +
SP4

"Update ESCD successfully".

Then my Microsoft USB optical mouse cannot be recognized under just for
once, and i re-connected the mouse while i'm at Windows Desktop, it is
recognized now and after that event, i don't get that message. "update
ESCD successfully"

I have 2 questions under lights of that experience:

1-Does "update escd successfully" message appear when there is a REALLY
hardware configuration change? Or can it apper although there is no
hardware configuration change such as USB connections?

2-I hardly remember i haven't changed my USB port of my mouse but after
2 days, i got "update ESCD successfully" and the mouse wasn't
recognized by Windows until i re-connect it at desktop screen.

Please clarify.

Thanks.

As far as I know, ESCD is only updated on a hardware change. The
current hardware configuration is compared to the previous
hardware configuration recorded in flash, and if there is a
difference, the flash is updated. (The BIOS chip has a
small area in the high addresses, used for the function.)
If there is no hardware change detected, there is no
need to update the DMI/ESCD.

It means that the BIOS is not consistently seeing the mouse
for some reason, during POST.

A possible workaround you could try, is find the USBPWR_12,
USBPWR_34, and USBPWR_56 jumpers in the manual. These determine
how a USB port is powered. If you set the power that the
mouse is on, to be powered by +5VSB, then the mouse power
will be on all the time. This may improve the odds that
the mouse will be seen and remains operational. But it
also means, that the LED used in the optical mouse, can
remain lit at all times. For someone who sleeps in the
same room as the computer, this would likely be an
unacceptable workaround. But I don't know of any other way,
to make the mouse happy.
