The encryption/decryption for int 13 depends on the BIOS implementation. Older BIOSes generally perform ATA or AHCI normal I/O in the same way as operating systems. However, the BIOS in Lenovo ThinkPad X220 uses SMM instead of direct I/O. BitVisor does int 13 encryption/decryption only if the int 13 performs normal I/O. > Also would there be any source code for bitvisor be available that is > later than the version of 1.3 on Source Forge?
