Upgrading the Main Memory
Upgrading the Main Memory
The main memory in your SPARCbook is provided by two single inline
memory modules (SIMMS) that can be changed without the use of tools
or other special equipment.
The process of upgrading your system’s memory consists of two basic
steps:
•
Fitting the new memory modules.
•
Reconfiguring the disk partitions to support the increased
memory size. This is necessary if you wish to use the Save and
Resume feature.
Reconfiguring the hard disk is a complex procedure with which you
may require the assistance of an experienced system administrator. An
alternative is to re-install the Solaris operating system from the Tadpole
CD (after making a complete backup of all important files on your
system). The Tadpole install program partitions the drive automatically
for the new memory size. However, this can be a very time-consuming
procedure.
Fitting new SIMMs
Caution
Always fit an identical pair of SIMMs (for example, two 64MB SIMMs). Other
combinations will not operate.
To avoid damaging your SPARCbook, observe antistatic precautions when
replacing the SIMMs. Use the grounding wrist strap supplied with the upgrade kit
and do not remove the new SIMMs from their antistatic bag until you are ready to
fit them.
Before replacing the SIMMS, make backups of any important files and then power
off using a system shutdown (see “Powering off using a system shutdown” on
page 1-7). The SPARCbook recognizes when the memory capacity of your computer
has changed but this can result in data loss if you use Save to power off your
computer before you change the memory modules.
