I will continue to look at it too although I am an amateur with hardware drivers. Out of curiosity, are my cards actually revision 2? In the Realtek driver, it looks like there are three revisions of the 8126, or is the first version something that was a test model? - 0x64800000: re_type = MACFG_90, calls re_set_mac_mcu_8126a_1 re_sw_ram_code_ver = NIC_RAMCODE_VERSION_8126A_REV_A - 0x64900000: re_type = MACFG_91, calls re_set_mac_mcu_8126a_2 re_sw_ram_code_ver = NIC_RAMCODE_VERSION_8126A_REV_B - 0x64A00000: re_type = MACFG_92, calls re_set_mac_mcu_8126a_3 re_sw_ram_code_ver = NIC_RAMCODE_VERSION_8126A_REV_C Sean -- scf@FreeBSD.orghome | help
