Hi @aerolite, my grub.cfg has those args set: set extra_args_918='earlycon=uart8250,io,0x3f8,115200n8 earlyprintk loglevel=15' set common_args_918='syno_hdd_powerup_seq=1 HddHotplug=0 syno_hw_version=DS918+ vender_format_version=2 console=ttyS0,115200n8 withefi elevator=elevator quiet syno_hdd_detect=0 syno_port_thaw=1 SasIdxMap=0 DiskIdxMap=08 SataPortMap=1' set sata_args=''

This actually works great. I am using a passed through Dell H200 HBA flashed to LSI IT-Mode. Also i am using a virtual SATA-Controller from ESXi with one disk in addition. The only thing i noticed is that you have to use common_args instead of sata_args to define your port mappings. The variable sata_args is ignored it seems. My mapping is this: Bay 1-8 Dell H200 Bay 9 VMware Disk
