Jumper
VID1. When the jumper is on pins 2 and 3, it allows four 256 KB x 4-
E0720
bit DRAMs to be installed in the DRAM sockets for a total of 1 MB of
video memory. When the jumper is on pins 1 and 2, it selects 512
KB of onboard video memory.
E0721
Lock Config. When the jumper is on pins 2 and 3, it prevents the
current system configuration maintained in the Flash BIOS from
being changed.
E0722
3C3VID. When the jumper is on pins 1 and 2, it changes the starting
address of the I/O registers to 46E8H from 03C3H.
NOTE
Memory
The server supports 4 MB and 8 MB (70 ns or 80 ns) (no 60 ns SIMMs). NEC or Mitsubishi
SIMMs can only be 70 ns.
For 16 MB and 32 MB SIMMs, speed must be 60 or 70 ns (no 80 ns SIMMs).
You must install memory modules in pairs (called banks) of matching size and speed; however,
the banks can be of different sizes and speeds.
If you install a pair of 16 MB or 32 MB memory modules, you must move the jumper for the
corresponding bank to the 2-3 position (Jumpers E0390, E0391, E0392).
Video Memory - DRAM
The video has 512 KB of RAM that allows pixel resolutions of 640 x 480 in 16 colors. You can upgrade the
server from 512 KB to 1 MB by installing four, 256 KB x 4 bit, 60 ns DRAMs in the four empty DRAM
sockets.

Function
Leave the BIOS Jumper DISABLED. The server stores its system information
(BIOS), built-in diagnostics, and other utilities on an erasable, programmable ROM
(EPROM) chip. The EPROM chip allows you to update this information from a
diskette. An update diskette will contain complete instructions. Leave the BIOS
jumper in the DISABLED position unless the HPUpdate Utility instructions direct you
to change the jumper to its ENABLED position. This jumper helps prevent any
destructive programs (viruses) from writing to the programmable ROM. After you
complete the BIOS update, always return the jumper to the DISABLED position.
Only DRAMs from certain manufacturers have been tested for compatibility with the
HP NetServer LM Series. Hewlett-Packard does not supply the DRAM upgrade.
Consult the HP PC Bulletin Board Service at 1-408-553-3500 for a current list of
supported DRAM upgrades.
