The information in this article applies to:

- Microsoft MS-DOS operating system versions 4.0, 4.01, 5.0, 5.0a, 6.0, 6.2, 6.21, 6.22

SUMMARY
=======

If you are using any of the Adaptec controller boards listed below with two hard
disk drives attached and you are using expanded memory (EMS), you need to obtain
the Adaptec ADAPTEC.SYS device driver. Without ADAPTEC.SYS, your machine will
stop responding (hang) when loading EMM386.SYS or EMM386.EXE

ADAPTEC.SYS can be obtained by contacting Adaptec technical support or from the
Adaptec bulletin board service (BBS).

RLL Controllers
---------------

  ACB-2370
  ACB-2370A
  ACB-2370B
  ACB-2372
  ACB-2372A
  ACB 2372B
  ACB-2372C

ESDI Controllers
----------------

  ACB-2320
  ACB 2320A
  ACB-2320B
  ACB-2322
  ACB-2333A
  ACB-2322B
  ACB-2322B-8
  ACB-2322B-16

The above controllers require the ADAPTEC.SYS driver because they use INT 60-67
to store drive tables. EMM386 also uses INT 67, which causes a conflict.

ADAPTEC.SYS relocates the drive tables from INT 60-67 to a reserved location in
random access memory (RAM). ADAPTEC.SYS should be loaded in the CONFIG.SYS file
before loading any MS-DOS 5.0 device drivers.
