The following instructions provide a method of upgrading the processor firmware of Apex PC Solutions OutLook Concentrators.
NOTE: This article assumes that you have the firmware upgrade EEPROM chip and are ready to install it.
- a small Phillips-head screwdriver
- a chip puller or small, flat-blade screwdriver
CAUTION: Before you perform any of the following steps, read the Precautionary Measures warning for your personal safety and to prevent damage to the computer system from electrostatic discharge.
- Perform the snapshot command to save current system settings; press the <Print Screen/SysRq> key.
The OSCAR Selection window appears on the display.
- Press the <F2> key.
The Advanced Menu screen appears with the Commands menu highlighted.
- Using the <Up Arrow> and <Down Arrow> keys, move the highlight to Snapshot and then press the <Enter> key.

Carefully remove the firmware EEPROM from its socket using a chip puller or a small flat blade screwdriver by alternately prying from each end.
CAUTION: Do not pry with excessive force or you may damage the circuit board or the chip socket.
- Carefully insert the new firmware EEPROM into the socket, ensuring that the orientation notch on the EEPROM chip matches the outline of the socket and drawing on the circuit board. Note the orientation mark on both the chip socket and on the circuit board. (Figure 2)
- Press firmly to ensure that the chip is seated flush in the socket. Visually check that all the pins of the new chip go straight into the chip socket.
- Replace the access coverplate.
Before you perform any of the procedures in this document, read the following caution for your personal safety and to prevent damage to the system from electrostatic discharge (ESD).
CAUTION FOR YOUR PERSONAL SAFETY AND PROTECTION OF THE EQUIPMENT.
Before you start to work on the system, perform the following steps in the sequence listed:
- Turn off your computer and all devices.
