In modules.conf

alias eth0 eepro100

appears at the end


In /etc/sysconfig/kernel
there was
INITRD_MODULES="e100"

I set this to

INITRD_MODULES=""

and rebooted
this had no apparent effect
the boot up on screen message ((from /var/boot.msg) still says

<5>Intel(R) PRO/100 Fast Ethernet Adapter - Loadable driver, ver 1.8.37
<5>Copyright (c) 2002 Intel Corporation
<5>
<5>eth0: Intel(R) 8255x-based Ethernet Adapter
<5>  Mem:0xfbfff000  IRQ:11  Speed:100 Mbps  Dx:Full
<5>  Hardware receive checksums enabled
<5>  cpu cycle saver enabled

During the boot up  the was also the message the e100 was loaded.

The UP DOWN messages appear frequently.  Are they a cause of the Hub
Link/Act LED flashing ?


Is IRQ11 "overused" ?

Dell No. 2 has eepro100 according to lsmod.

the /var/log/messages shows that eepro100 v1.09 is used  with eepro rev 
1.36.
a receiver lockup bug exists and -- enable work-around
plus addition information


First things first:  how the heck do we get rid of replace e100 with 
eepro100 ?
