TO ALL MANDRAKE EXPERTS HELP ME

THE SITUATION:
MY OPERATING SYSTEM IS LINUX MANDRAKE AND LINUX SLACKWARE.
I BOOT FROM MANDRAKE.
I HAVE TW0 NIC THE 3COM 3C509B AND BROADCOM BCM94306.
ALL THOSE TWO NIC'S ARE CONNECTED TO THE INTERNET.
I AM CONNECTED TO A PROXY SERVER.
I USED MY 3COM NIC TO CONNECT ME TO THE INTERNET.
I USED STATIC IP FOR THIS NIC(3COM).
I USED THE COMMAND modprobe 3c509 for my 3com nic.
(nevermind the Broadcom)

MY PROBLEM:
only my slackware can connect me to the internet.
my mandrake cannot,
ive tried pinging my ip or my loopback .. it did replied ,,
but if i ping my proxy server the says network destination unreachable.
It is important for me to connect my mandrake to the internet, because i will be using it for some important purposes.

I have tried reconfiguring all network configuration of mandrake. but it has no effect.

PLS GIVE ME TIPS OR HINT IN CONFIGURING MANDRAKE.

No need to yell

Can you post the output of ifconfig (run as root) ? Preferably those of both slackware and mandrake, so we can see what's different.

Can you ping an external ip ? E.g. ping 216.239.59.99 (google.com). If you can, make sure your DNS configuration is correct. You can find that in /etc/resolv.conf

Also, with the two cards, are you sure it is the right one that you have configured. Perhaps you have configured the broadcom instead of the 3com

[B]ive tried pinging my proxy server this the output from my Linux slackware(my os that can connect to the internet)

I can see one difference in the network addresses : your slackware has a
netmask of 255.255.255.128 whereas your mandrake has 255.255.255.0. Try changing that.

Could you also please post the output of 'route' from both systems ? I would like to know the settings of your default gateway

THIS IS THE SOLUTION
With lilo you can do this by selecting the os you would like to boot, lets say it is named mandrake and add the option to it.

boot: mandrake acpi=off
