(This is why I passed the drive number in dl.) The partition being booted from is the active partition. Quite some time ago a program appeared on the net called MultiBoot. This program allows you to choose your boot partition at boot time. (There was a similar program posted a few months ago, but I haven't read its source.) MultiBoot adjusted the partition table in RAM, so that the only active partition was the one that was actually being booted.
