Here is a brief explanation of drive specifications: Type: The BIOS contains a table of pre-defined drive types. Each defined drive type has a specified number of cylinders, number of heads, write precompensation factor, landing zone, and number of sectors. Drives whose specifications do not accommodate any pre-defined type are classified as type user. Size: Disk drive capacity (approximate). 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 usually detects the correct video type automatically. 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. For EGA, VGA, SEGA, SVGA, or PGA monitor adapters. Color Graphics Adapter, power up in 40 column mode. Color Graphics Adapter, power up in 80 column mode. 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. [. . . ] SRAM Static RAM, unlike DRAM, does not need to be refreshed in order to prevent data loss. Thus, it is faster, and more expensive. S1590 Trinity 100AT 71 Appendix 1 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. [. . . ]
