I am trying to install BOCA 4 port serial card.

I have managed to compile the kernel properly, and managed to
test the card on the stand alone (FreeBSD 486) machine,
Dial-in and dial-out both works fine. But when I put 
same card and the same kernel on the other (FreeBSD 486) machine
with Eithernet card, my network (Internet connection) goes down and 
I get following message:

ep0 not found at 0x300
is0 not found at 0x280
le0: no board found at 0x300
ifconfig: ioctl(SIOCGIFFLAGS): no such interface.

After removing the card but keeping the same kernel networks runs fine.
I do get following message regarding some address conflict, but the network 
operates fine.

Part of the dmesg
-----------------
1 3C5x9 board(s) on ISA found at 0x300
ep0 at 0x300-0x30f irq 10 on isa
ep0: aui/utp[*UTP*] address 00:20:af:76:02:b2
is0 not found at 0x280
le0 not probed due to I/O address conflict with ep0 at 0x300
ze0 not probed due to I/O address conflict with ep0 at 0x300
npx0 on motherboard

Serial port has the following addresses: 

sio4 at 0x100-0x107 flags 0x705 on isa
sio4: type 16550A (multiport)
sio5 at 0x108-0x10f flags 0x705 on isa
sio5: type 16550A (multiport)
sio6 at 0x110-0x117 flags 0x705 on isa
sio6: type 16550A (multiport)
sio7 at 0x118-0x11f irq 12 flags 0x705 on isa
sio7: type 16550A (multiport master)

Q. Why the conflict between "le0 or ze0" and "ep0"  matters when the serial
   card is inserted in the system?
Q. What is le0?
Q. Any suggestions to solve the problem?


Thanks in advance.
