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. Tushar
