1-2 Technical Information
SIMM UPGRADE
PowerMate P ETC Series system configurations come with 16 MB of main system memory.
Six sockets on the system board support up to 384 MB of high-speed memory using the
following industry-standard, tin-plated, single in-line memory modules (SIMMs):
NOTE: You may install 60-ns, parity or
nonparity, extended data output (EDO) SIMMs
into the SIMM sockets.

1-MB by 32- or 36-bit (4-MB stick)

2-MB by 32- or 36-bit (8-MB stick)
 4-MB by 32- or 36-bit (16-MB stick)
 8-MB by 32- or 36-bit (32-MB stick)

16-MB by 32- or 36-bit (64-MB stick).
CAUTION: To avoid corrosion between
different metals, only use tin-plated SIMM sticks.
Performing Memory Upgrades
Upgrade system memory as follows:
 locate memory sockets on system board
 check installed system memory
 install SIMMs.
Locating SIMM Sockets.
Remove the system unit cover and locate the six SIMM sockets on the system board (see
Section 3 of the PowerMate V & P Series Service and Reference Manual).
If any cables block access to the SIMM sockets, label and disconnect them. If any boards
block access to the sockets, remove them.
Checking System Memory
Use Table 1-2 to check the memory installed in the system and determine the SIMM
configuration needed to increase memory.

Technical Information 1-3
NOTE: SIMM memory must be installed in
pairs of the same memory type.

INTERRUPT CONTROLLER
The interrupt controller operates as an interrupt manager for the entire AT system
environment. The controller accepts requests from peripherals, issues interrupt requests to
the processor, resolves interrupt priorities, and provides vectors for the processor to
determine which interrupt routine to execute. The interrupt controller has priority
assignment modes that can be reconfigured at any time during system operations.
The interrupt levels are described in Table 1-4. Interrupt level assignments 0 through 15 are
in order of decreasing priority. See Section 2 of the PowerMate V & P Series Service and
Reference Manual for information on changing the interrupts using Setup.

provided at the rear of the system unit. Figure 1-1 shows the location of the network
interface board and the three connectors. For more information, see Section 2 of this
addendum.
