The fields show the total installed random access memory (RAM) and amounts allocated to base memory, extended memory, and other (high) memory. RAM is counted in kilobytes (KB: approximately one thousand bytes) and megabytes (MB: approximately one million bytes). RAM is the computers working memory, where the computer stores programs and data currently being used, so they are accessible to the CPU. Modern personal computers may contain up to 64 MB, 128 MB, or more. The DOS operating system and conventional applications use this area. Extended Memory: Above the 1-MB boundary. Early IBM personal computers could not use memory above 1 MB, but current PCs and their software can use extended memory. Total Memory: Displays the total memory in the system. BIOS S2380 Trinity K7 39 Chapter 3 BIOS Configuration Advanced BIOS Features The screen (shown on the following page) contains industry-standard options additional to the core PC AT BIOS. This section describes all fields offered by Award Software in this screen. The example screen below may vary from the one in your Setup program. Your system board designer may omit or modify some fields.

You should then run an anti-virus program. Keep in mind that this feature protects only the boot sector, not the entire hard drive. Note: Many disk diagnostic programs that access the boot sector table can trigger the virus warning message. If you plan to run such a program, we recommend that you first disable the virus warning. CPU Internal Cache/External Cache Cache memory is additional memory that is much faster than conventional DRAM (system memory). [. . . ] In Sleep/Suspend mode, all devices except the CPU shut down. SRAM Static RAM, unlike DRAM, does not need to be refreshed in order to prevent data loss. In Standby mode, the video and fixed disk drive shut down; all other devices operate normally. http://www. tyan. com 70 UltraDMA/66 is a fast version of the old DMA channel. Without UltraDMA your system cannot take advantage of the higher data transmission rates of the new UltraATA hard drives. [. . . ]
