gigabit ethernet configuration (acenic and redhat 7)

[william l kleb]

(long-time listener, first-time caller)

so i managed to get the network-side of a prototype "guarded" beowulf up
with redhat 7.0 using the two onboard ethernet controllers on a 1U tyan
2510 running a couple piii 866's -- this newbie is still amazed (virtual
no prior sysadm experience).  you (and the linux community in general)
generate a bunch of useful(!) documentation.

anyway, the hole i've dug now has me stumped (apparently i can't take
a hint -- see below ;).  i am trying to install a netgear gigabit card
(ga620t) in the tyan's 64-bit/66MHz pci slot and use it in place of one
of the onboard eepro controllers going into the netgear fs518t 10/100/1000
switch (16+2).

lspci says: 01:02.0 Ethernet controller: Netgear: Unknown device 630a (rev 01),
ifconfig doesn't list it, netcfg talks about 'Delaying eth2 initialization'
and 'insmod acenic' exclaims,

  Using /lib/modules/2.2.16-22smp/net/acenic.o
  /lib/modules/2.2.16-22smp/net/acenic.o: init_module: Device or resource busy
  Hint: insmod errors can be caused by incorrect module parameters, including
  invalid IO or IRQ parameters

as is probably obvious from the above, i have no idea what i'm talking about;
but i am not above groveling for answers -- or at least re-direction ...

thanks,
