Try this command before loading the eepro100 driver module:

	setpci -s 0:0.1 14.L=0x8

It seems that the latest openbios doesn't program the PCI bridge registers
appropriately.

Hi,

I am trying to install Intel eepro100 onto WalnutPPC405GP.
Basic PCI settings seem good but no frame is transmitted.
The environment is WalnutPPC305GP with HardHatLinux 2.4.2 from
MonraVista.

I can read or write eepro configuration registers and other control
registers via PCI memory space.
But Bus Master operations do not seem functional. I am confirmed that
MASTER operation bit in eepro100 is enabled.
I think some more settings are needed for PPC405GP built-in
PCI control
registers and/or Walnut board jumpers/dipswitches.

Has anyone tried PCI cards with BUS MASTER operations for Walnut
PPC405GP?

Thanks in advance,

Hideo
