Memory
There are four DIMM sockets on the system board for memory expansion Follow these simple rules when you plan to
install additional memory DIMMs:
•Use only HP DIMMs listed on the Technical Reference Label located inside the HP NetServer top cover,
in Information Assistant, or in Order Assistant.
•DIMMs can be 32 MB, 64 MB, or 128 MB in any combination.
•DIMMs can be installed in any order in any of the four DIMM sockets.

CAUTIONOnly install DIMMs on a system board that is lying flat on a static-dissipating work surface.
Do not rock the DIMM into place, but apply firm and even pressure directly downward.
Video Memory
Expand video memory by installing two 256 K x 16 (512 KB), 70 Ns, 40-pin SOJ package DRAM ICs.
CAUTION Install the chip in the correct orientation. Failure to do so will destroy the DRAM..

Boot Device Priority
The boot device priority is controlled by the Boot Device Ordering submenu of the Configuration menu of the Setup
utility.
•IDE CD-ROM drive with bootable CD-ROM
•Flexible Disk with bootable flexible disk
•Embedded SCSI controller
•PCI boards in slots in the following order: 6, 5, 4, 3, 2, 1.
•Hard Drive Priority: Allows you to rearrange the order in which hard disk drives are searched for the operating
system. All hard disk drives in the system are listed, as well as any bootable ISA board.

DIMM Status Error Codes
When no processor error condition exists, the DIMM slot LEDs display the status of the DIMMs in the corresponding
slots, as follows:
•OFF: no DIMM installed
•Flashes ON and OFF at 1 Hz in 50/50 proportion of time: uncorrectable error or inappropriate DIMM
•Flashes ON and OFF at 1 Hz in 90/10 proportion of time: non-HP DIMM installed
•ON: HP DIMM installed
