(provided on the Ready-to-Configure CD that comes with your computer), many types of functions, such as data transfers, software updates, and POST and BIOS updates can be performed remotely on your PC and other computers enabled for Wake on LAN that are linked to your network. This updating can be done after hours and on weekends, which saves time and increases productivity. Users are not interrupted during normal working hours and LAN traffic is kept to a minimum. Refer to "Wake on LAN" on page 58 for further information. Other features such as remote program load (RPL) and dynamic host configuration protocol (DHCP) also allow a network administrator to remotely control your computer. If you use remote program load in conjunction with LANClient Control Manager software, you can use a feature called Hybrid RPL. Using LANClient Control Manager, you set up your computer by installing hybrid images (or files) on the hard disk. Then, each time the computer starts from the network, LANClient Control Manager recognizes your computer as a Hybrid RPL client and a bootstrap program is downloaded to your computer. This bootstrap program is small and helps prevent network congestion. Working from the hybrid images, the bootstrap program initiates the startup process from the hard disk of your computer. An advantage to Hybrid RPL is that the network load associated with standard RPL is avoided. Refer to "RPL and DHCP" on page 56 for further information. System Programs System programs are the basic layer of software built into every IBM PC. They include the power-on self-test (POST), the basic input/output system (BIOS) code, and the Configuration/Setup Utility program. POST is a set of tests and procedures that is performed every time you turn on your PC. The BIOS is a layer of software that translates instructions from other layers of software into instructions that the computer hardware can understand. Using the Configuration/Setup Utility program, you can view and change the configuration and setup of your computer. In the past, the system programs were contained in a read-only memory (ROM) module on the system board. If you wanted to update POST routines, BIOS instructions, and the Configuration/Setup Utility program, you had to disassemble the computer and replace modules, or you had to replace the system board. Now, the system programs are stored in an EEPROM (electrically erasable programmable read-only memory) module, which is also referred to as a flash memory. The contents of an EEPROM module can be easily updated with an update (flash) diskette. The process of updating the system programs EEPROM is often referred to as flashing the BIOS. As part of the continuing work to improve quality, IBM might make changes and enhancements to the system programs. When updates are released, they will be 28 Using Your Personal Computer
