The easiest way to edit the MAC address & Serial No is to install Ext2Fsd on a Windows PC, then just insert the USB stick that has had the Synology DS3612xs - DSM 4.2 build 3202 img file written to it. It will then appear as just another drive.

Hi Aigor, Many thanks for your assistance & your clear instructions. I've now managed to edit the grub.conf file, just need to boot from it now & see if it's worked.

Hi Aigor, thanks for your reply. I'm running Debian 6 in a VM where I have the img file also. to mount the img file I've run the following to find the sextors: # fdisk -lu SynoBoot_3612xs_4.1++.img You must set cylinders. You can do this from the extra functions menu. Disk SynoBoot_3612xs_4.1++.img: 0 MB, 0 bytes 255 heads, 63 sectors/track, 0 cylinders, total 0 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xf6eba356 Device Boot Start End Blocks Id System SynoBoot_3612xs_4.1++.img1 * 63 32129 16033+ 83 Linux SynoBoot_3612xs_4.1++.img2 32130 224909 96390 83 Linux I've then run: # mount -t auto -o loop,ro,offset=61 SynoBoot_3612xs_4.1++.img.img /mnt/dsm but get an error saying I must specify a filesystem type. What am I doing wrong!

I want to change the MAC address & serial number but can't work out how to mount the img file so that I can edit it, could someone please give me clear instructions on how to do this Please. Many thanks
