I've some problems configuring my ethernet on a PC with following
configuration (hw/sw):
hw: HP Pavilion, AMD K6(tm) 3D processor, PCI.
sw: Win '98 on /dev/hda1; RedHat 5.2 on /dev/hda4.

A) In win 98, from Control Panel:
     PCI DEC 21041 & SIS 7001 PCI to USB Open Host Controller
     have both the same  interrupt, irq=3.
I can't change the interrupt if Ethernet card from BIOS or win 98.

B) In /proc/pci (RedHat), my Ethernet card has assigned the irq 255, the

as the Sis 7001 Controller. Here, I enclosed the relevant info regarding

my ethernet card:


%>cat /etc/conf.modules
alias eth0 tulip
alias sound cs4232
alias midi opl3
options opl3 io=0x388
options cs4232 io=0x534 irq=5 dma=1,0 mpu_base=0x330 mpu_irq=9
options tulip  io=0xf880


%> ifconfig eth0
eth0      Link encap:Ethernet HWaddr 00:80:C8:46:01:CA
          inet addr:  Bcast:

          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          Interrupt:255 Base address:0xf880

I used the all tulip versions from tulip pages ! all failed !
Please help.
