[. . . ] The system can support Pentium II processors running at 233, 266, 300, 333, 350, and 400 MHz and Celeron processors running at 266 MHz. Internal Cache Size This parameter specifies the first-level or the internal memory (i. e. , the memory integrated into the CPU) size, and whether it is enabled or disabled. External Cache This parameter specifies the second-level cache memory size currently supported by the system. The available cache sizes are 256 KB or 512 KB (depending on the CPU installed). For information on how to configure the system memory, see Memory Configuration. Floppy Drive A This parameter specifies the system's current diskette drive A settings. Floppy Drive B This parameter specifies the system's current diskette drive B settings. Chapter 3 BIOS Utility 3-5 IDE Primary Channel Master This parameter specifies the current configuration of the IDE device connected to the master port of the primary IDE channel. IDE Primary Channel Slave This parameter specifies the current configuration of the IDE device connected to the slave port of the primary IDE channel. IDE Secondary Channel Master This parameter specifies the current configuration of the IDE device connected to the master port of the secondary IDE channel. IDE Secondary Channel Slave This parameter specifies the current configuration of the IDE device connected to the slave port of the secondary IDE channel. Total Memory This parameter specifies the total amount of onboard memory. The memory size is automatically detected by BIOS during the POST. If you install additional memory, the system automatically adjusts this parameter to display the new memory size. 1st Bank/2nd Bank/3rd Bank The 1st Bank, 2nd Bank, and 3rd Bank parameters indicate the type and size of DRAM installed in DIMM sockets 1, 2, and 3 respectively. The None setting indicates that there is no DRAM installed. For the location of the DIMM sockets, refer to the System Board Layout in Chapter 2. 3-6 AcerAltos 500L User's Guide Serial Port 1 This parameter shows the serial port 1 address and IRQ setting. Serial Port 2 This parameter shows the serial port 2 address and IRQ setting. Parallel Port This parameter shows the parallel port address and IRQ setting. PS/2 Mouse The BIOS utility automatically detects if there is a pointing device connected to your system. If there is, this parameter displays the Installed setting. Otherwise, it is set to None. Chapter 3 BIOS Utility 3-7 Product Information The Product Information contains the general data about the system, such as the product name, serial number, BIOS version, etc. This information is necessary for troubleshooting (may be required when asking for technical support).

Choose None if you do not have a second floppy drive. 3-10 AcerAltos 500L User's Guide LS-120 Drive Compatible As This parameter allows you not only to enable the LS-120 device installed in your system, but also to specify the function of the device. The setting affects how BIOS will detect the device. Possible settings are: · · Normal In this setting, BIOS does not support the LS-120 drive. [. . . ] CPU Multiple This parameter sets the Core/bus ratio of your system. The clock speed of the bus does not necessarily equal the CPU's (core). The bus clock speed is often slower than the CPU clock speed. Processor Speed The processor speed is the speed at which a microprocessor executes instructions. [. . . ]
