[. . . ] 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. 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. 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. Floppy Disk Drives Choose the memory capacity and disk size that corresponds with that of your floppy disk drive(s). You can ignore this setting if you are using a VGA monitor since VGA BIOS automatically configures this setting. Halt When the system is powered on, BIOS performs a series of diagnosis tests called POST (Power On Self Test). You can tell BIOS to halt on all errors, no errors, or not to halt on specific errors. 22 Award BIOS Setup Program 3-2 Advanced BIOS Features By choosing the Advanced BIOS Features option from the Standard CMOS Features menu (Figure 3-1), the screen below is displayed.

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. [. . . ]
