User manual CHAINTECH 6VIA3

[. . . ] Declaration of Conformity According to 47 CFR, Parts 2 and 15 of the FCC Rules The following designated product: EQUIPMENT: MAINBOARD MODEL NO. : 6VIA3 is a Class B digital device that complies with 47 CFR Parts 2 and 15 of the FCC Rules. Operation is subject to the following two conditions: 1. This device may not cause harmful interference. This device must accept any interference received, including interference that may cause undesired operation. [. . . ] You must enter values indicated in the table below into each drive parameter field. This information should be included in the documentation from your hard disk vendor or system manufacturer: TYPE CYLS HEAD PRECOMP LANDZ SECTOR MODE Setting method Number of cylinders Number of heads Write precompensation cylinder Landing zone Number of sectors Mode type Table 3-1 Hard Disk Drive Parameters Cyls/Head/Sector: The number of Cylinders, Heads, and Sectors can usually be found written on the top of the hard disk. If you have a relatively new hard drive, entering this information alone is usually sufficient for normal hard disk operation. The hard disk will not work properly if you enter improper information for these categories. Precomp: Older hard drives (i. e. , MFM or RLL drives) have the same number of sectors per track at the innermost tracks as at the outermost tracks. Thus, the data density at the innermost tracks is higher and the bits are lying closer together. Even though the physical size of a sector gets progressively smaller as the track diameter diminishes, each sector must still hold 512 bytes. Write precompensation circuitry compensates for the difference in sector size by boosting the write current for inner track sectors. Landz: This defines the address of the landing zone and is only used for older hard drives which do not have an auto-parking feature. Mode: If the Type value is not None for any device, you must set the Mode value for that device. There are four different Mode values: Auto, Normal, Large, and LBA. Auto - BIOS detects and enters the IDE drive type during boot up. Normal - for IDE drives that meet the old IDE specification which support a maximum capacity of 528MB (1024 cylinders, 16 heads, and 63 sectors). Large - for IDE drives that do not support LBA and have more than 1024 cylinders. Try this setting if your hard disk does not operate properly with 21 User's Manual the LBA setting. Large mode is not supported by all operating systems, i. e. , only certain versions of DOS support large mode. LBA - (Large/Logical Block Addressing) With LBA, the IDE controller transforms the data address described by sector, head, and cylinder number into a physical block address, significantly improving data transfer rates. This mode is for drives with greater than 1024 cylinders and between 528MB and 8. 4GB in size. This protocol is the current common standard. Choose None for Type if there are no IDE HDD devices in your system. You can use the IDE HDD Auto Detection function to auto detect your hard drive parameters. Using this function will automatically insert the parameters discussed under Hard Disk Setup and will indicate User for the Field value. [. . . ] For normal operation, disable this function. B. CPU Host Clock (CPU/PCI) The CPU Host Clock feature allow your to select a timing combination for the CPU and the PCI bus. 36 Award BIOS Setup Program 3-9 Load Fail-Safe Defaults Load Fail-Safe Defaults loads the default BIOS values directly from the Standard CMOS Features menu (Figure3-1). If the stored record created by the setup program becomes corrupted and therefore unusable, these defaults will be loaded automatically when you turn on the computer.
