Other DOS application software products can also operate with the Access
program provided they do not interfere with the normal functions of the
system configuration. Interference occurs when programs do any of the
following:

 Overlay the DOS or BIOS area of storage

 Program the 8259 interrupt controller in a way that interferes with
the Access program's use of that controller

 Disable interrupts, fail to issue an end-of-interrupt or IRET on a
hardware interrupt level, or mask selected interrupt levels for more
than 100 milliseconds

 Use interrupts 13, 25, or 26 for access to the virtual disk

 Configure hardware device registers that belong to the network
hardware used by the Access program

 Make incorrect use of timer interrupts

 Open more than 127 files (that is, require the presence in the
config.sys file of a files command with a value greater than 127)

 Use memory not assigned to them by the operating system.

The Access program can store DOS files on the host AIX system's fixed-disk
drives. This virtual drive allows DOS to interface with the AIX system as
if the AIX host were a fixed-disk drive.

You can use most DOS commands with files that the Access program stores on
the AIX host. However, since AIX handles all disk-management functions
for the virtual drive, the following DOS commands cannot be used for the
virtual drive:

assign
chkdsk
diskcomp
diskcopy
fdisk
format
label
print
sys
tree.

Unpredictable results can occur if you issue one of these commands for the
virtual drive or a file on the virtual drive.
