WORKS controllers in networks which carry heavy traffic.

Restrictions and Limitations

To create a floppy key disk, a disk greater than or equal to 720KB is

required for booting purposes.

Any application that does not properly mask and unmask interrupts is

incompatible with this product. For example, applications that use IBM

BASICA, Version 1.0 interpreter or compiler or GW BASIC(R), Version 1.0

do not unmask the interrupts when they exit. In these cases, a BASIC

program must be interpreted or recompiled using a version of BASIC that

would unmask the interrupts.

For IBM Personal Computer AT(R)-compatible configurations with EGA or

VGA graphics adapter, the DEPCA Revision E or later is required to uti-

lize EMS.

For asynchronous DECnet network connections, all client functional-

ity and network services are supported, except:

o NETBIOS naming service and datagrams.

o Remote boot.

o Local area disk services provided through the Local Area Systems

Transport (LAST) protocol. (The user can access virtual disks via

NDU in an asynchronous DECnet environment.)

o LAT.

o PC DECwindows Motif.

o Microsoft Windows, Version 3.0/3.1 running in Standard or Enhanced

Mode.

Simultaneous Ethernet network activity and non-DECnet asynchronous com-

munication via the asynchronous port results in character loss on the

asynchronous port.
