Boot DOS utility before Windows?

[Gordon Hughes]

We wrote a secure erase utility here at UCSD, to erase all
data from a HDD before donating, selling on eBay, or
upgrading it.

Windows NY & above won't allow direct HDD access, so we
write a DOS program.

How to we tell Windows to boot this DOS program before
booting Windows?
....Like Scandisk does, or Norton Disk Doctor does.

=Thanks

Assuming the system(s) have the floppy drive first in the bios boot device
list, run the dos program from a dos bootable diskette.

If you attempt to run any program within the OS that deletes a partition,
modifies or formats a partition, it certainly can't lock the partition its
running from. Windows 2000 does allow direct HD access, but you can't change
the floor matt if you're still standing on it.
