PCI-Systems which are not equipped with an EISA-Bus behave in the same way as an ISA

mainboard with regard to the available RAM memory. NetWare therefore does not auto-

matically recognize the available memory above 16 MByte. The command 'Register Mem-

ory' allows the registration of memory above 16 MByte.

Memory shortage can appear while loading several applications simultaneously on the

server, especially where large volumes are concerned. This is because the Register Memory

Command is normally carried out in the autoexec.ncf file. This is usually located in the

SYS-Volume.

An autoexec.ncf file placed in the DOS-Partition of the NetWare Server helps to get around

this problem. In order to carry out this process, the disk driver has to be removed from the

startup.ncf and inserted into the autoexec.ncf in the DOS partition. In this case, the disk

driver has to be loaded directly after the Register Memory command. An example of an

autoexec.ncf file:

LOAD C:GDTRP312

....

In addition, a further start file can be loaded on the SYS volume for differentiation, e.g.,

with the name 'autonet.ncf'.

The following problem often occurs when installing NetWare 4.1 server: While copying the

module cdrom.nlm the system hangs - forever. This problem only occurs when the CD-ROM

drive's name under MS-DOS is 'cdrom', i.e., the config.sys/autoexec.bat contains the fol-

lowing files:

DEVICE=aspicd.sys /D:cdrom

and

mscdex /D:cdrom

To avoid this problem, simply change the CDROM's name in DOS to another name, i.e., use

'/D:scsicd' instead of '/D:cdrom'.

High server utilization, combined with a large number of applications running on the server

often leads to the following problem: The number of 'Dirty Cache Buffers' increases tre-

mendously and the server is then not stable. In order to avoid this situation, the following

parameters should be modified:

1. Increase the number of concurrent disk cache writes for the disk subsystem:

set maximum concurrent disk cache writes

This parameter can be increased up to 500 for high performance controllers and fast hard

disks.

2. Decrease the delayed write standard parameter:

set dirty disk cache delay time
