***For experienced individuals comfortable with synology and linux command line, I take no responsibility for any issues encountered*** ***Read fully before considering*** Please read all necessary documentation for setting up Xpenology before reading this guide. Try the start-here guides below: https://xpenology.com/forum/forum/83-faq-start-here/ This guide docuements the process of using Linux to modify the synoboot.img for your environment and writing to a usb hard drive. Additonally, this guide shows the upgrade process from 6.1.7 to 6.2.2 with extra drivers (extra.lzma file), your use case my not have the same requirements, so please make you know the process for your environment regardless of the directions shown here. Collect required files ***this guide is using synology model 3617, adjust accordingly for the model you want to use*** Recommended to save your files to a unique folder on your system, in this example we will use folder "xpenology-3716-20200215" (model and timestamp) Download the 6.2 boot loader from this post: https://xpenology.com/forum/topic/12952-dsm-62-loader/ Downloaded extra drivers files from this post (this post also includes links to the synology pat file as well): ***Extra Drivers are only needed if your devices are not supported by the current boot loader files*** https://xpenology.com/forum/topic/21663-driver-extension-jun-103b104b-for-dsm622-for-3615xs-3617xs-918/ Download the synology pat file (from the post above) Extact files for modifications Extract synoboot zip file unzip synoboot_3617.zip -d synoboot Extract extra drivers zip file unzip extra3517_v0.5_test.zip -d extra_lzma Extract Synology DSM pat file ***Requires 7zip*** Install 7zip for your linux distribution (example shown is Ubuntu) sudo apt install p7zip-full p7zip-rar Use 7zip to extract pat file 7z -odsm x DSM_DS3617xs_24922.pat Your folder should now have 3 new folders within as shown ls -1 Output: dsm <--- new folder DSM_DS3617xs_24922.pat extra3617_v0.5_test.zip extra_lzma <--- new folder synoboot <--- new folder synoboot_3617.zip Create mount folders to modify synoboot.img files make these folders to mount the partitions of the synoboot.img for editing mkdir usb mkdir usb/part1 mkdir usb/part2 mkdir usb/part3 Mount synoboot.img partitions First view the partition layout of the synoboot.img for mounting information fdisk -l synoboot/ds3617_6.2/synoboot.img Output: Disk synoboot/ds3617_6.2/synoboot.img: 50 MiB, 52428800 bytes, 102400 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 Disklabel type: gpt Disk identifier: B3CAAA25-3CA1-48FA-A5B6-105ADDE4793F Device Start End Sectors Size Type synoboot/ds3617_6.2/synoboot.img1 2048 32767 30720 15M EFI System synoboot/ds3617_6.2/synoboot.img2 32768 94207 61440 30M Linux filesystem synoboot/ds3617_6.2/synoboot.img3 94208 102366 8159 4M BIOS boot Important mounting information Units byte size: here its 512 bytes Start byte for each partition: to mount these partitions you need to multiply the start byte by the unit byte size for the offset Mount partition 1 (we use bash arithmetic expansion to multiple the offset) sudo mount -o loop,offset=$((512*2048)) synoboot/ds3617_6.2/synoboot.img usb/part1 Mount partition 2 sudo mount -o loop,offset=$((512*32768)) synoboot/ds3617_6.2/synoboot.img usb/part2 Mount partition 3 ***This partition does not get modified and does not need to be mounted, but shown for those interested in looking at the contents*** sudo mount -o loop,offset=$((512*94208)) synoboot/ds3617_6.2/synoboot.img usb/part3 Collect required hardware information for modifying grub.cfg in partition 1 Get USB vid/pid information ***Run this command before plugging in your usb drive*** lsusb Output: Bus 002 Device 002: ID 8087:0024 Intel Corp.

Hi, Well, I am a newbie here, and it is a bit off, so sorry for that. But I am looking for help with the DSM porting, and I thought this is the best place where I Can ask my questions. I have an ARMv5 NAS, and I decided to install the DSM-111's fw on it (6.1.5 extracted from the pat file). It boots up fine, and I Can see the Diskstation login: over serial console. But I have no NIC support. Maybe because the kernel doesn't support my RTL8168 NIC by default? I Could see these errors and informations in the console about the network: [ 10.950000] ERROR: sflash_probe - Failed to initialize the SFlash.Loading Marvell Ethernet Driver: [ 10.960000] o Cached descriptors in DRAM [ 10.960000] o DRAM SW cache-coherency [ 10.970000] o 2 Giga ports supported [ 10.970000] o Single RX Queue support - ETH_DEF_RXQ=0 [ 10.970000] o Single TX Queue support - ETH_DEF_TXQ=0 [ 10.980000] o TCP segmentation offload (TSO) supported [ 10.980000] o Receive checksum offload supported [ 10.990000] o Transmit checksum offload supported [ 10.990000] o SKB Recycle supported - (Enabled) [ 11.000000] o Rx descripors: q0=128 [ 11.000000] o Tx descripors: q0=532 [ 11.010000] o Loading network interface(s): [ 11.010000] o register under mv88fx_eth platform [ 11.020000] o eth0, ifindex = 2, GbE port = 0 [ 11.020000] o eth0, phy chipid = fffffff0, Support WOL = 0 [ 11.030000] [ 11.030000] Warning: Giga 1 is Powered Off cat: can't open '/proc/sys/kernel/syno_skip_vender_mac_interfaces': No such file or directory [ 21.930000] eth0: started udhcpc (v1.16.1) started eth0 Link encap:Ethernet HWaddr <removed> UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:532 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:11 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Also, I tried to compile the kernel module manually, but as I Could see, the magic numbers are differs. $ readelf -h ./8192cu.ko ELF Header: Magic: 7f 45 4c 46 01 01 01 00 00 00 00 00 00 00 00 00 Class: ELF32 Data: 2's complement, little endian Version: 1 (current) OS/ABI: UNIX - System V ABI Version: 0 Type: REL (Relocatable file) Machine: ARM Version: 0x1 Entry point address: 0x0 Start of program headers: 0 (bytes into file) Start of section headers: 6346960 (bytes into file) Flags: 0x5000000, Version5 EABI Size of this header: 52 (bytes) Size of program headers: 0 (bytes) Number of program headers: 0 Size of section headers: 40 (bytes) Number of section headers: 5069 Section header string table index: 5066 $ readelf -h ./lib/modules/2.6.32.12/kernel/net/netfilter/nf_conntrack.ko ELF Header: Magic: 7f 45 4c 46 01 01 01 61 00 00 00 00 00 00 00 00 Class: ELF32 Data: 2's complement, little endian Version: 1 (current) OS/ABI: ARM ABI Version: 0 Type: REL (Relocatable file) Machine: ARM Version: 0x1 Entry point address: 0x0 Start of program headers: 0 (bytes into file) Start of section headers: 37228 (bytes into file) Flags: 0x600, GNU EABI, software FP, VFP Size of this header: 52 (bytes) Size of program headers: 0 (bytes) Number of program headers: 0 Size of section headers: 40 (bytes) Number of section headers: 265 Section header string table index: 262 The first one is the original one, and the second one is a manually compiled module using the Marvell 6281 6.1 GPL sources.
