Re: configuration EEPROM enables Sleep Mode

Thanks Donald.    Hmm.   Actually I did try it with the eth0 "up" before 
that, and it said:

/usr/local/bin/eepro100-diag -e

eepro100-diag.c:v2.12 4/15/2003 Donald Becker ([email protected])
http://www.scyld.com/diag/index.html
Index #1: Found a Intel Pro/100 VE (type 1031) adapter at 0x7000.
A potential i82557 chip has been found, but it appears to be active.
Either shutdown the network, or use the '-f' flag.

Since (I think) I had seen somewhere that it's not a good idea to run the 
diag with -f on an in-use eth0, I decided to choose the first of those 
options and wait till I was about to shut the machine down, with the eth0 
"down".     So I'm a bit confused.   Is there a difference between "active" 
and "up"?     I would play about with it and find out if I could but right 
now I have connections running on it so will have to wait until I shut them 
down again.    Should I then ifconfig eth0 up AND use -f?     Or is this 
something to do with whether the cable is plugged in?      Remember - I know 
almost nothing about eth0.

The *-bug lists now either forward to the regular driver lists or are
disabled.  Each list gets about a hundred spam messages a day, so I've
been reducing the number of lists.

With smaller memory systems the 2.2 kernels have better performance than
most 2.4 kernels.  And with 512MB-2GB, the 2.2 kernels were much better
than 2.4 kernels before 2.4.17.

Bring the interface 'up' to pull it out of ACPI-D3 low-power mode before
running 'eepro100-diag -f ...'.
