[. . . ] 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 disk-checking program. Cyls: Number of cylinders Head: Number of heads Precomp: Write precompensation cylinder Landz: Landing zone Sector: Number of sectors Mode: Auto, Normal, large, or LBA Auto: The BIOS automatically determines the optimal mode. Normal: Maximum number of cylinders, heads, and sectors supported are 1024, 16, and 63. Large: For drives that do not support LBA and have more than 1024 cylinders. LBA (Logical Block Addressing): 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 with greater than 1024 cylinders. http://www. tyan. com 38 Drive A, Drive B Select the correct specifications for the diskette drive(s) installed in the computer. None No diskette drive installed 360K, 5. 25 in 5- 1/4 inch PC- type standard drive; 360 kilobyte capacity 1. 2M, 5. 25 in 5- 1/4 inch AT- type high- density drive; 1. 2 megabyte capacity 720K, 3. 5 in 3- 1/2 inch double- sided drive; 720 kilobyte capacity 1. 44M, 3. 5 in 3- 1/2 inch double- sided drive; 1. 44 megabyte capacity 2. 88M, 3. 5 in 3- 1/2 inch double- sided drive; 2. 88 megabyte capacity Video Select the type of primary video subsystem in your computer. The BIOS supports a secondary video subsystem, but you do not select it in Setup. EGA/VGA CGA 40 CGA 80 MONO Enhanced Graphics Adapter/Video Graphics Array. Monochrome adpater, includes high resolution monochrome adapters. BIOS 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 S1590 Trinity 100AT POST does not stop for any errors. If the BIOS detects any non- fatal error, POST stops and prompts 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. 39 Chapter 3 BIOS Configuration 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 counted in kilobytes (KB: approximately one thousand bytes) and megabytes (MB: approximately one million bytes). RAM is the computer's working memory, where the computer stores programs and data currently being used, so they are accessible to the CPU. Early IBM personal computers could not use memory above 1 MB, but current PCs and their software can use extended 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. BIOS Features Setup 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. [. . . ] 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 memory where any byte can be accessed without touching the adjacent data, is often used to refer to the system's main memory. 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. [. . . ]
