Hi everyone, Currently, I have 3 different bootloader with SLIC 2.1 support. 1) Hazard bootloader 2) Vista bootloader with SLIC 2.1 (modified by me) 3) Wow In (1) and (2), the original grub bootloader is modified with the SLIC table built-in. In (1) and (3), the SLIC table can not be selected while I can choose which one I want with (2). But since (1) and (2) use a modified grub loader, I am thinking if M$ may be able, one day, to detect the bootloader and disable activation in Vista/W7. With WOW, since the grub boot loader is original (simply load a 98 floppy image that load grub4dos after modifying SLIC info), may be harder to detect. So, which one should I use? All the 3 bootloaders works perfectly on my Toshiba (phoenix) and my EEE (AMI). I am just concerned about future detection by M$... Thanks!
