Hallo i got a Mainboard from an HP xw9400 Workstation but it looks there is something wrong with the MAC address from both onboard nic's. Now i search an way to change the MACs via DMI or how ever this can be possible. The Bios can be found here Its an OEM Tyan s2915 Mainboard and Tyan itself use a Phoenix bios. I tryed to already to flash the original Tyan Bios but the Tyan flashtool didnt want to flash as the DMI is wrong(dif). Any hints or infos i can try to fix this ?
