I just installed RH7. Following installation, I noticed my 3Com NIC
(3C900B) was not defined as a device. I added an eth0 3c90x definition to
my module config file, did a modprobe and it loaded OK. When I then try
to defining/activating eth0 with dhcp, I get the following error:
dhcpstart: ioctl SIOCSCIFFLAGS: no such device
Steps to Reproduce:
1. See Description
1) What does ifconfig say?
2) What does "strace -f -e ioctl dhcpd" say?
Just figured out my problem - I was also following a bug report regarding
a similar problem with my SB Live card not working under RH7 - the Bug
Reporter suggested changing my BIOS "PnP OS?" to NO. Once I did that and
rebooted RH7, it magically detected both my SB Live and 3Com NIC, both of
which work fine now.
Problem is that I use my machine for W98 as well, which doesn't seem to
like having "PnP OS?" set to NO (I get odd conflicts upon boot).
Is there something else I'm missing so that I run RH7 with "PnP OS?" set
There's really no good answer for this.
