Installed The sections below explain the parameters. 3-4 AcerAltos 500L User's Guide Processor The Processor parameter specifies the type of processor currently installed in your system. The system supports Intel Pentium II processors. Processor Speed The Processor Speed parameter specifies the speed of the processor currently installed in your system. The drive needs the LS-120 device driver to operate. Drive A BIOS recognizes the LS-120 drive as drive A. If a standard diskette drive A exists, BIOS automatically identifies it as drive B. If a standard diskette drive B exists, it automatically becomes inaccessible. If two LS-120 drives exist, BIOS recognizes them as drive A and drive B, respectively. · · Drive B BIOS recognizes the LS-120 drive as drive B. If a standard diskette drive B exists, it becomes inaccessible. Hard Disk BIOS recognizes the LS-120 drive as a hard disk. In this setting, format the LS-120 drive as any other hard disk and assign it a drive letter C, D, E, and so on. See the documentation that came with the LS-120 drive for more information. IDE Drives To configure the IDE drives connected to your system, select the parameter that represents the channel and port where the desired hard disk to configure is connected. The options are: IDE Primary Channel Master This parameter lets you configure the hard disk drive connected to the master port of IDE channel 1. Chapter 3 BIOS Utility 3-11 IDE Primary Channel Slave This parameter lets you configure the hard disk drive connected to the slave port of IDE channel 1. IDE Secondary Channel Master This parameter lets you configure the hard disk drive connected to the master port of IDE channel 2. IDE Secondary Channel Slave This parameter lets you configure the hard disk drive connected to the slave port of IDE channel 2.
