From 7405a133101e009c760b98dd4dbcdc49b82ec3b3 Mon Sep 17 00:00:00 2001

Subject: combine block device load commands into common function

All the raw block load commands duplicate the same code. Starting with
the ide version as it has progress updates convert ide, usb, and scsi boot
commands to all use a common version.
