No, you set the block size to 2, so you are seeking (2 * 255) or 512
bytes into the disk.
But I already indicated the 466 bytes are null... in another usb
drive I
tested,
thus no boot signature - and yet, bios hung forever because that disk
was 2nd
in boot order after cd/dvd drive, and before internal HD.
So, the laptop's BIOS is executing what? A good code for moving from disk
to disk until it finds the bootable drive in the boot sequence specified?
Clearly in this case - it does not do so.
And yet, you insist it is not a flaw.
