Sorry if this question already and weak in English. LAN Card installed, the DEC / Intel 21143 and clones 10/100 Ethernet (quard ports) with the error report. Code:dc0: dc_setcfg: failed to force rx to idle state. dc1: dc_setcfg: failed to force rx to idle state. Operate on a FreeBSD 8.2 i386 mainboard atom D425KT, LAN card can be installed on a PCI 32bit, pci-X active, mainboard atom D425KT slot Pci only 1 slot@ 32 bit. Use the ifconfig command to see that appearing macadress = ff: ff: ff: ff: ff: ff on dc0, dc1. The dc2, dc3 work normally. Try to disable ACPI, it has the same effect. Then test deployment on the Windows xp, 7 use a normal 4 port same mainboard.
