No, it all goes in a tiny fraction of a second. Normally, you don't see
any of the messages.
I think other people also tried VirtualBox, and said it doesn't work. It
doesn't even load the remaining sectors from the drive. This is done via
BIOS interrupt 0x13:
I think VirtualBox doesn't support this interrupt call.
