Hey all, Been a lurker here for quite a while, usually don't want to contribute to floods of noob questions. Enough browsing and searching typically will lead me to answers on here. But I've been trying to figure this out for a couple days now and can't, so I'm finally posting So... VirtualBox can load an SLIC table easily with the VBoxManage tool using VBoxManage setextradata "vm name" "VBoxInternal/Devices/acpi/0/Config/CustomTable" "path to slic.bin" This works great for the purposes of Windows 7 OEM Licenses, etc. The Windows 8 generation uses the MSDM table, this can also be loaded via VBoxManage. However as far as I can tell, VBox only allows for one "CustomTable" (slic OR msdm). In certain cases, specifically Windows Server 2012 R2, it would be ideal to have both SLIC and MSDM tables as it seems this may help the 1058 event problem. So I'm thinking either there is some configuration method in VBox that would allow me to load a "SLIC.bin" and a "MSDM.bin" separately or some way to combine them together into a single "SLIC&MSDM.bin" file. I've tried smashing them together with a Hex Editor, but I don't have much of an understanding of how ACPI tables are defined or separated. When I try to just append the data from one to the other in a single file, it seems only the first table gets passed through. (So if I take SLIC.bin data and append it to a MSDM.bin, I only get a MSDM table in the VM). Anyways, that is where I am stuck. Any thoughts? Thanks in advance.
