Driver for hard disks attached to Atari ST(E) via ACSI port

It can drive SCSI disks attached via ACSI-SCSI adapter. Tested on Mega STE, ST with Satandisk and Steem with Pasti.  Accessible capacity limit is 1GB (Group 0  SCSI commands with 21-bit addressing).

Easy data transfer between PC and Atari is goal. Therefore DOS partitioning is supported. Drive must be partitioned on PC, and on Atari FAT16 BigDOS partitions will be usable (33MB -1GB). Freeware program BigDOS must be started from AUTO folder for correct work. Recommended partition sizes are up to 511MB, because of speed. 
Program will work even with disks without partition table, with single FAT16 partition - as XP usually formats removable drives. In that case, autoboot is not possible (installer will abort with message that no place).
  Do not use partitions under 32MB by bigger drives (over ~100MB) - because BigDOS will disable them. By smaller drives make all partitions under 32MB, and then no need for BigDOS (use logical unit size of 1024 bytes by format (set)).
  At version 0.6 there is XHDI support together with FAT32 support. FAT32 will work only under Mint. To get Mint working: copy at it's partition begin AUTO (with MINT000.PRG) and MINT directories (+TERADESK for instance). Don't put BigDOS in AUTO folder by Mint! It may be any partition - just swap it with C by autoboot to enter Mint. 
Autoboot: it is possible on Atari even with PC partitioned disks.
Run program AUBACD07.PRG from floppy for install. Place BigDOS (in AUTO folder) at begin of C partition, so it can be accessed before runs!. 
It will work only with TOS 2.06, 1.04, 1.06 (not 1.02). To avoid driver loading after reset hold down ALT key.
ACSID6.PRG is for running driver from floppy, and is otherwise same as above.

Only ACSI target 0 is supported for now.
Transfer speed is about 1MBytes/sec, if drive can do it.
