hi all, I have followed (possibly?) outdated guide to compiling a modified BIOS and activating windows 7 64 KVM guest. The host is debian 7 64bit. the title of the link is "Crafting an SLIC BIOS for Linux KVM Guests ". you can find it in these forums in you append to the FQDN : /threads/33723-Crafting-an-SLIC-BIOS-for-Linux-KVM-Guests The process has failed meaning that the activation has not gone forth, so I wonder if this guide still works. A few key differences that I can note between the guide and my case: - I had already installed windows when I stumbled upon this guide. In fact I skipped adding a product key at the time. Other than that I used the gigabyte .bin file to mod the seasbios, added a valid product key from "Windows 7 OEM SLP Key Collection" (for win7 ultimate - didn't find a specific one for Gigabyte) and installed the certificate from gigabyte too (v2.1). still windows are not activated. - patching seabios with seaslic's patch did not complete successfully. only 2 out of 3 changes got applied. The reason being that the 3rd change needs to replace some code in <seabios.submodule>/src/acpi.c, line 800 or so. while file acpi.c has merely ~650 lines of code (also I can not find the relavant part anywhere)... so I could not apply the 3rd patch . Any clues as to how I can complete the actiavtion? thank you in advance for your help.
