Installing a BootPROM Chip
Installing the BootPROM chip is a straightforward task, but you must take
care to ensure that components are not damaged. Be sure you
understand the following instructions before installing the chip.
Caution
Risk of equipment damage:
Before removing an adapter card, attach an earth ground to the PC
chassis. If an earth ground is unavailable, ensure that the power is
switched off and plug in the PC's grounded AC power cord.
Caution
Wear an anti-static wrist strap when handling ROMs. As an
additional measure, do not touch the ROM's connectors. Leave the
ROM in its anti-static packaging when not in use.
Caution
If the network adapter card is installed in the system, remove it
before installing the chip. Refer to your system’s hardware
documentation for instructions on how to remove adapter cards.
The BootPROM chip will be either square or rectangular. The square chip
has an angled corner that must be oriented to match the angled corner of
the socket, as shown in Figure 116. The rectangular chip has a notch in
one end that must be aligned with the notch on the socket, as shown in
Figure 117.
To install the chip, do the following:
1. If the network adapter card is already installed in the system, power off
the computer and remove the adapter. Do not attempt to install the
chip with the network adapter card in the system.
2. Remove the BootPROM chip from its anti-static packaging.
3. Position the chip on the empty socket on the network adapter card.
