I'm interested in Windows7 SoftMOD method. I wanna make my own activator software. My mobo BIOS has no SLIC. I wanna use GRUB because it is made of C and ASM. The following is my flow chart. 1. Allocate and insert SLIC on ram when GRUB stage2 code runs. 2. Reallocate XSDT/RSDT because of insertion SLIC address. 3. Change XSDT/RSDT address in RSDP. Is my logic possible? SLIC allocation, XSDT/RSDT reallocation and modification RSDP... Are these all possible? If the all are possble, where is the best location for SLIC allocation and XSDT reallocation? EBDA? GRUB stage2 code segment? or conventional memory(free for use)?
