Just tried to add the SLIC file to the existing coreboot tianocore image build without `select HAVE_ACPI_SLIC` and re-installed W10 Pro but it wouldn't activate.
From some research it seems like SLIC isn't directly used to activate a copy of Windows but is instead used to authenticate an OEM product key for offline activation. Apparently you still need to enter in the product key when SLIC is being used. MSDM on the other hand does just contain a product key. It also seems like SLIC is only used on Windows 7 and older, whereas 8 and newer need MSDM.
`cbfstool currentok.rom add -f SLIC -n fallback/slic -t raw` It gives an error code 0xC004F213, after that also tried adding the MSDM as a additional raw payload but that gave error 0x803f7001. `cbfstool currentokslic.rom add -f MSDM -n fallback/msdm -t raw`
Looking through the code, coreboot doesn't support a `fallback/msdm` file. Instead, `fallback/slic` can be either a SLIC table or an MSDM table. So if should be something like `cbfstool currentok.rom add -f MSDM -n fallback/slic -t raw`. I'm assuming that MSDM file from the command you tried is `/sys/firmware/acpi/tables/MSDM`?
If you have both SLIC and MSDM should both be applied, or does the `HAVE_ACPI_SLIC` create somekind of reference/link to the added fallback files?
As I mentioned before, `HAVE_ACPI_SLIC` no longer exists as it was removed in CB:7202 due to the new code making it unnecessary.
---------------------------------------- Support #585: acpi MSDM / SLIC table usage? https://ticket.coreboot.org/issues/585#change-2041
* Author: Walter Sonius * Status: New * Priority: Normal * Category: Documentation * Target version: none * Start date: 2025-03-20 * Affected OS: Windows 8 Pro / Windows 10 Pro ---------------------------------------- What option(s) does one need to compile this feature into a coreboot & edk2 build and where does one put the `slic_file` and in what format?
Couldn't find anything in the documentation nor the commits that introduce MSDM/SLIC support: https://review.coreboot.org/c/coreboot/+/44995 https://review.coreboot.org/c/coreboot/+/7202
