XEN OWNER'S HANDBOOK
Upgrading the Apricot XEN
Chapter 5
Memory upgrades
The XEN motherboard is fitted with sockets for four SIMMs
(Single In-line Memory Modules) these allow system RAM to be
expanded to up to 128Mbytes using standard 72 pin, 70 nS
SIMMs.
The SIMM sockets are located at the front of the motherboard,
beneath the 5.25" drive bay.
SIMMs must be installed in pairs. Each pair is called a bank, bank
0 is formed by the pair of sockets nearest the hard disk drive
bay, bank 1 is formed by the pair nearest the processor.
Apricot supplies 1 Mbyte (256kx36), 2 Mbyte (512kx36), 4
Mbyte (1Mx36), 8 Mbyte (2Mx36), 16 Mbyte (4Mx36) and 32
Mbyte (8Mx36) SIMMs, giving upgrade capacities of 2, 4, 8, 16,
32 and 64 Mbytes. Any combination of these capacities is possible,
using any capacity in either of the two pairs.
Installation
In order to install a memory upgrade you must:
1.
Power the system down.
2.
Take suitable anti-static precautions and remove the
system unit cover.
If you are unfamiliar with Apricot’s recommended anti-
static precautions and/or the process of removing the
system unit cover refer to Appendix A.
The SIMM connectors are located beneath the 5.25"
drive bay. In order to install a memory upgrade you
must remove the 5.25" drive bay.
3.
If there is a 5.25" drive fitted disconnect the power and
signal cables from the rear of the drive.
If no drive is fitted unclip the power cable from the
drive bay.
4.
Remove the two screws that secure the drive bay and
slide the bay backwards.
