Since the sudden end of Truecrypt development, I was asked to take an inside look at Diskcryptor ( https://diskcryptor.net/wiki/Downloads ) Especially wanted was the PXE booting of a whole encrypted partition, so I was assuming that when Diskcryptor spurted out the PXE boot file, it would contain the keyfile with it. I experienced lots of strange problems. The PXE booting does not work on an (old, admittedly) HP DC7600 Convertible Minitower PC. The PXE boot error message is always only 496 kb ram detected; 512 kb RAM required. -> WTF? My machine has 6 GB Ram! So I could not boot, so I re-applied some Ghost image to the HP machine and installed Diskcryptor again, with different boot parameters, sometimes with different keyfiles and sometimes with password prompt at booting or not. The PXE bootloader saved by Diskcryptor is always 19.653 bytes; I compared several versions of it and boy, there was a large surprise: I could not spot the 64 supposed to be different bytes from the included keyfile in different versions of Diskcryptor! Sometimes the difference between different PXE boot images were as tiny as 5 bytes, despite I was using different keyfiles supposed to be included within. So this begs the question: Where does Diskcryptor save the auth keyfile, then...? On the encrypted harddisk? Pretty useless if you ask me.... Support from the forum or via e-mail is terrible. Anyone else made these strange experiences with Diskcryptor, or has an idea of how to fix that darned PXE bootloader? Oh, and no use to save the bootloader to CD-ROM iso image and burn it and boot - same too less memory problem... :-(
