[. . . ] Drives whose specifications do not accommodate any pre-defined type are classified as type user. Note that this size is usually slightly greater than the size of a formatted disk given by a diskchecking program. Number of cylinders Number of heads Write precompensation cylinder Landing zone Number of sectors Auto, Normal, large, or LBA The BIOS automatically determines the optimal mode. Maximum number of cylinders, heads, and sectors supported are 1024, 16, and 63. During drive accesses, the IDE controller transforms the data address described by sector, head, and cylinder number into a physical block address, significantly improving data transfer rates. For drives w ith greater than 1024 cylinders. Size: Cyls: Head: Precomp: Landz: Sector: Access Mode: Auto Norm al Large LBA (Logical Block Addressing) Drive A Select the correct specifications for the diskette drive(s) installed in the computer.

The BIOS supports a secondary video subsystem, but you do not select it in Setup. EGA / VGA Enhanced Graphics Adapter / Video Graphics Array. Monochrome adapter, includes high resolution monochrome adapters. CGA 40 CGA 80 MONO Halt On During the power-on self-test (POST), the computer stops if the BIOS detects a hardware error. You can tell the BIOS to ignore certain errors during POST and continue the boot-up process. These are the selections: No errors All errors All, but keyboard All, but diskette All, but disk / key POST does not stop for any errors. If the BIOS detects any non-fatal error, POST stops and primpts you to take corrective action. POST does not stop for a keyboard error, but stops for all other errors. POST does not stop for diskette drive errors, but stops for all other errors. POST does not stop for a keyboard or disk error, but stops for all other errors. BIOS Memory You cannot change any values in the Memory fields; they are only for your information. The fields show the total installed random access memory (RAM) and amounts allocated to base memory, extended memory, and other (high) memory. RAM is the computer's working memory, where the computer stores programs and data currently being used, so they are accessible to the CPU. RAM is counted in kilobytes (KB: approximately one thousand bytes) and megabytes (MB: approximately one million bytes). Modern personal computers may contain up to 64 MB, 128 MB, or more. Base Mem ory Typically 640 KB. The DOS operating system and conventional applications use this area. Extended Mem ory Above the 1 MB boundary. Early IBM personal computers could not use memory above 1 MB, but current PCs and their softw are can use extended memory. DOS may Other Mem ory load terminate-and-stay (TSR) programs in this area, such as device drivers, to free as much conventional memory as possible for applications. [. . . ] Novice end users can simply plug them into a computer that is running on a Plug and Play-aware operating system (such as Windows 95), and go to work. Devices and operating systems that are not Plug and Play require you to reconfigure your system each time you add or change any part of your hardware. The term RAM (Random Access Memory), while technically referring to a type of http://www. tyan. com 64 memory where any byte can be accessed without touching the adjacent data, is often used to refer to the system's main memory. This memory is available to any program running on the computer. ROM (Read-Only Memory) is a storage chip which contains the BIOS (Basic Input/ Output System), the basic instructions required to boot the computer and start up the operating system. [. . . ]
