Problem With 2.9.39 and IRQ

I´m trying to install a RouterOS v 2.9.39 and doesn´t recognizes my 5 (five) eth cards.

I have this setup:

Mother Asus P4S8X-X Rev 1.01 Bios Ver 1002 Chipset 648
P 4 2.66 Ghz Processor
5 (five) 3com 905C-TX-M Network Cards
Nvidia Gforce 4 MX 4000
1 X 256 DDR
8 Chips

AGP Slot Gforce 4 MX 4000
PCI Slot1 Empty
PCI Slot2 3com 905C-TX-M
PCI Slot3 3com 905C-TX-M
PCI Slot4 3com 905C-TX-M
PCI Slot5 3com 905C-TX-M
PCI Slot6 3com 905C-TX-M


/system resource pci print

NAME MTU MAC-ADD ARP

0 ether1 1500 00:10:22:FF:C1:3E ENABLED
1 ether2 1500 FF:FF:FF:FF:FF:FF ENABLED
2 ether3 1500 00:10:22:FF:C3:65 ENABLED
3 ether4 1500 72:A2:72:A2:72:A2 ENABLED

Ether1 = PCI3
Ether2 = ???
Ether3 = PCI5
Ether4 = ???

I have try every single bios setting and didn´t worked.

How could it be ?

Thanks a Lot

If you can physically identify which ethernet card is not being recognized, you might swap it into one of the PCI slots that is known to work, just to test that you don’t have a bad network card. (You can verify this by checking if you have a different MAC address for one of the NICs.)

Otherwise, if it is an IRQ conflict, be sure to read your motherboard manual to see which slots share an IRQ. To resolve this, you may have to bump a NIC down one slot and/or disable unnecessary things in the BIOS such as USB, serial and LPT ports, or even the secondary IDE channel.

Always disable unnecessary stuff in your BIOS that might take up an IRQ.

When I execute /system resource pci print command only figures 4 cards (not 5) and with the same IRQ=255 …

Now I tried to switch cards into different pci slots and when execute /interface ethernet disable “n” and then enable show me this output:

“action failed (6)”

I think the problem is the mother: Asus P4S8X-X Rev 1.01 Bios Ver 1002 Chipset 648

Someone know if it compatible ?.



Thanks

dear all
good post I think that this that have not been recognized

1 ether2 1500 FF:FF:FF:FF:FF:FF ENABLED
coz : Mac is not valid this mac is reserved to arp request and not valid to be mac to NIC
