Award BIOS is a trademark of Award Software Incorporated. [. . . ] 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 applica tions 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. Other Memory: Between 640 KB and 1 MB; often called High memory. DOS may load terminate-and-stay-resident (TSR) programs, such as device drivers, in this area, to free as much conventional memory as possible for applications. Lines in your config. sys file that start with loadhigh load programs into high memory.

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). CPUs from 486-type on up contain internal cache memory, and most, but not all, modern PCs have additional (external) cache memory. When the CPU requests data, the system transfers the requested data from the main DRAM into cache memory, for even faster access by the CPU. The External Cache field may not appear if your system does not have external cache memory. [. . . ] SRAM Static RAM, unlike DRAM, does not need to be refreshed in order to prevent data loss. Thus, it is faster, and more expensive. S1894 Tigercub 100 83 Appendix 2 Glossary In Standby mode, the video and fixed disk drive shut down; all other devices operate normally. UltraDMA/33 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. [. . . ]
