I'm endeavouring to pre-load a modified DSDT table using grub2. The syntax I've tried being as shown below, after which I chainload to Win10. This being done on a Dell E6540 with Win10 and grub 2.02 (or older.. tried many versions, same result).
acpi --load-table dsdt /efi/dsdt.aml
Then I do 'acpidump -b' to peruse the DSDT table. In all cases, it
remains the same system BIOS one, not my modified /efi/dsdt.aml one.
I've also set 'set debug=all' and can see grub2 is reading my modified dsdt file and doing memory writes.
So two questions:
1. Is 'acpi' not capable of loading a DSDT table for use with Win10?
2. if that is the case, is there some 'memload' or 'writefromfile' type command where I give a memory address and a file which grub2 can then write? The idea is simply to replace the existing DSDT at it's address with one given by the file of same size or smaller.
