Root/
| Source at commit 340 created 13 years 10 months ago. By azimutz, Ok.. as i mentioned about the "drivers" override key, this stuff is mostly based on the search algo on search_and_get_acpi_fd, acpi_patcher.c; i just added 2+2 and got 5 in return :) No need to check for ramdisk presence anymore, courtesy of Zef, rev 264. Why check the root of the ramdisk (rd) instead of /Extra? Well, rd's can be aliased as bt(0,0) or not, and the behavior is pretty diff in both situations; a "normal" rd can load "single" files and the paths to it start with rd(0,0). | |
