AST-NETBIOS MEMORY USE
AST-NETBIOS uses RAM memory to perform network functions similar
to the ROM found on IBM's PC Network board. One of the features
of this method was that current users of AST-PCNET and PCNET II
could update existing software without requiring a hardware
change.
However, due to the RAM memory used by DOS, AST-NETBIOS, and
IBM'S PC LAN program, users have found it necessary to trim
memory use to load large application programs. The following
information will aid in optimizing AST-NETBIOS for this purpose:
1. AST-NETBIOS is default configured for a
"REDIRECTOR" configuration and takes about
75K bytes of RAM. On the server PC, the
NETWORK Program alone requires 256K bytes of
memory and NETBIOS must be increased to
handle the load (as per the README file
found on AST-NETBIOS 1.0-1.3 disks). Any
increase in the NETBIOS parameters specified
will consume memory as per the list below.
a. Open sessions used 112 bytes of
memory per open session.
b. Commands used 112 bytes of
memory per command.
c. Small packets used 416 bytes
per packet.
d. Large packets used 1184 bytes
per packet.
This information was obtained by running PC-DOS Version 3.20
CHKDISK commands on a non-network drive. An IBM PC/XT was used,
the version of NETBIOS was Version 1.30.
