Most ethernet drivers accept parameters to specify a base IO address and an IRQ as follows:
io=base_addr irq=irq
For example, for a 3com 3c509 ethernet card located at IO address 210 (IO addresses are usually in hexadecimal) and IRQ 10, use the following parameters for the 3c509 driver:
io=0x210 irq=10
You can use multiple ethernet cards in one machine
. If each card uses
a different driver (e.g., 3c509 and a DE425), you simply need to add
aliases (and possibly options) for each card to
/etc/conf.modules; for example:
alias eth0 3c509 options 3c509 io=0x210 irq=10 alias eth1 de4x5 options de4x5 io=0
See Section 8.2.2 for more information.
However, if any two ethernet cards use the same driver (e.g., two 3c509's or a 3c595 and a 3c905), you will need to compile a custom kernel with the ethernet driver built in. In that case, you can use the ``classic'' LILO boot: parameters of the form:
ether=irq,base_addr,interface
For example:
LILO boot: linux ether=10,0x210,eth0 ether=11,0x300,eth1
(For more information about using more than one ethernet card, see the Multiple-Ethernet mini-HOWTO.)
