SIMM Installation
Your computer comes with 2MB, 4MB, or 8MB of memory on
memory mod&s-also called SIMMs (single inline memory
modules). By installing additional SIMMs, you can increase
the amount of memory in your computer up to 16MB.
There are four SIMM sockets on the main system board, and
each can contain one SIMM. You can use 1MB and 4MB
SIMMs.
The following table shows the possible SIMM configurations;
do not install memory in any other configuration. The label
on the system board for each SIMM socket (RAM1 through
RAM4) identifies the bank of sockets where you should install
SIMMS.

Video Memory
The computer may come with 512KB or 1MB of video
memory. You can increase the video memory to 1MB by
installing four video DRAM DIP (Dual Inline Package) chips
(44256), 70ns.
For the memory to work properly, you must install one chip
in each socket.

Installation/Support Tips
Installing Diskette Drives
Q
Make sure that the drive type has been correctly selected
in the SETUP program.
0
Make sure jumper J13 is set to position 1-2 to enable the
diskette drive controller.
Software Problems
P
When installing a copy-protected software package, first
try the installation at high speed. If this does not work
properly, select low speed by pressing Ctrl Alt - (using the
numeric keypad). Try loading the program at low speed
and then switching to high speed, if possible.
c3
When running a software package that uses a key disk as
its copy-protection method, try loading it at high speed. If
this does not work, load it at low speed.
Installing Option Cards
Cl
If you are installing a video adapter card that doesn’t
support VGA, make sure you disable the built-in VGA by
removing jumpers J1 and J2.
COM Port Assignment
0
If you want to assign COM1 as COM3, you must set
jumper J7 to position 2-3. If you want to assign COM2 as
COM4, you must set jumper J9 to position 2-3.

Change Notices
Installing Hard Disk Drives
If you are installing a drive that cannot use the embedded
IDE interface, such as an ESDI hard disk drive, it is
recommended that you use a 16-bit, AT-type hard disk
controller. If you install a non-IDE hard disk drive and
controller card, you must set jumpers J14 and J16 to
position 2-3 to disable the built-in IDE hard disk drive
interface. Also be sure to remove the hard disk drive
ribbon connector from the system board.
When installing a hard disk drive, see the hard disk drive
type tables on pages 6 and 7 and use the auto-sensing
feature in SETUP to select the correct type number for the
drive. If the auto-sensing feature does not produce a
match for the drive, you can define your own drive type
by selecting User
entering the drive’s exact parameters.
