The latest hard disk driver from Supra (version 2.61) fully supports
both multiple physical drives and will let you write a boot sector
out to the drive (to drive 0, if you have multiple drives).  This
will even let you run your system without floppies if you desire.

What they do is to put a file "supboot.sys" (marked hidden so that it
doesn't show up in normal directory listings) onto the root of drive C.
Supboot.sys is the full driver; the simple driver in the boot sector
just knows how to load that file.

To get around the previously mentioned problems with booting directly
from a hard disk (i.e., what to do if there are broken auto folder
programs or broken desk accessories, etc.) the Supra boot sector
checks for the control, shift and alternate keys to see if they all
are down; if so, it doesn't try to boot from the hard disk, which
lets you try to fix the situation using floppies.
