With HD_Patch you can edit the patchable variables of your Atari AHDI
hard disk driver. Only AHDI versions 3.00 and above may be changed.
Read the HELP file for more details before you do anything.
Use this program at your own risk and take it 'as it is'.
This program is not Public Domain (Atari owns the rights) but you may
upload it into other Mailboxes and as long as you don't ask money for
it and you don't edit or patch it.
