Hi...... Sorry for my bad English and the inconvenience. When I flashed to Beta 9, I selected FORCE ERASE ALL in USB Burning Tool - I made the update identically the picture below (I have NOT marked the third and the fourth option) Now I'm having a problem: evertime that I reboot (or turn off-on) the Minix, I get a new MAC Address - always different. So I can't use a fixed IP in my Router, cause the MAC change. (I use only Ethernet Connection) I did another flash (beta 9) with NORMAL ERASE, but the problem persists. Is there any way to get my Minix again with a fixed MAC Address for Ethernet???? Thank for everything..... detail: the seventh and the eighth picutre of the post How to flash the (beta) firmware image (http://www.minixforum.com/attachments/7-jpg.20/ ; http://www.minixforum.com/attachments/8-jpg.21/) is selected FORCE ALL ERASE.
