Sovled: A bit of work, but I was able to modify the config of a Marvell 88E8001 base slot card and apply it to the mainboard. Thanks to the guys that wrote the Linux driver for the card! BTW: Be _really_ careful not to have duplicate NICs when updateing PROM info. If you still would like to share your ASUS P5GZ-MX Eprom -that be great!

S...! Using the Marvel utility YUKONVPD.EXE I erased the on-board options EPROM, which results is non-detection by the BIOS and essentially uselessness (?word?). If anyone has a default (original) FLASH e-Prom (e.g. ROM file) for the Marvel onboard LAN Marvel Yukon 88E8001 that would be awesome! I have contacted ASUS but the board is way past warranty. The GigaByte FAQ gigabyte.com -> support -> FAQ, search for EEPROM and find a link labeled 'here' that leads to faq_marvell.eeprom.zip, which contains the tool you need from a 'trusted source'. You can also use it to modify your MAC address. Boot DOS: YUKONPVD -R 88e8001.raw Will read the EEPROM for the Controller and save it to '88e8001.raw', a Hex-Dump or the file would save my board. Matt
