don't need, 1. good hw design should use one serial EEPROM to store MAC address, So when flash the BIOS, the EEPROM is still there. in ck804_nic.c will read MAC from serial EEPROM in SMBUS (bus num and device num is set in Mainboard Config.lb), at first. 2. even for bad design, you can keep your own romstrap.inc/lds in your mainboard dir, and modify Config.lb to point corrent file. In such case, you need special flash util to keep your MAC address or read the MAC address at first, and then set it back....

I'd like to suggest that the romstrap files be moved from

to mainboard, because the files are board specific with a

address. Also the ck804_nic.c files needs a mainboard specific get_mac_address() that resides in mainboard.
YhLu, can you fix this? it's a good point.

yes, but there were some sis-630 based cards several years ago that stored MAC in FLASH and CMOS.
SO to upgrade FLASH: - make sure address is in cmos - write flash - write MAC back to flash.
There are some stupid designs out there.
