dual eepro100 bootnet.img fails
Last modified: 2007-04-18 12:33:29 EDT
Description of Problem:
7.1 bootnet.img fails to initialize either eth0 or eth1 (when chosen
in dialog prompt) when both are eepro100 devices. symptom is both
assigned same IRQ if you check on the kernel messages VC.
further steps such as DHCP, or ftp after manual IP configuration,
fail to establish network connections.
SGI RH7.1+XFS modified bootnet.img does not have this problem on
the same hosts.
host: intel 440GX server platform, dual 550 MHz PIII,
onboard and PCI card eepro100 adapters; ours are VALinux nodes.
Steps to Reproduce:
1. obtain platform
2. boot with bootnet.img
3. choose an interface and try to continue
stuck at point where network traffic is attempted, as if
network link is failing.
boot into 2nd-stage ramdisk.
The installer does not assign IRQ's. This must be specific to the hardware
becuase I've used quite a few Compaq's with dual on-board eepro100 NICs with no
problems. Reassiging to the kernel.
Let me guess: the SMP kernel works just fine.
You can use the bootdisk from
for this, if you provide the "apic" parameter to syslinux.
This is a bug in the BIOS where it gives misinformation about IRQ routing
on the motherboard.
