1-14Hard Disk Block ModeThis function enhances disk performance depending on the hard disk in use.BIOS automatically detects if your hard disk supports this feature.Setting this function to Auto allows data transfer in blocks (multiple sectors) toincrease the data transfer rate. If your system does not boot after setting thisparameter to Auto, change the setting to Disabled. The default setting for thisparameter is Auto.Advanced PIO ModeThe advanced PIO mode feature improves system performance by allowingthe use of faster hard disk drives. If your hard disk supports this feature, youmay set this parameter to Auto (default), Mode 0, Mode 1, Mode 2, Mode 3, orMode 4 depending on the hard disk requirements. See the documentation thatcame with the hard disk.If your hard disk does not support this function, set this parameter to Disabled.Hard Disk Size > 528MBThis enhanced IDE feature works only under DOS and Windowsenvironments. If set to Auto, which is the default, BIOS allows you to use ahard disk with a capacity of more than 528MB. This is made possible throughthe Logical Block Address (LBA) mode translation. You may be required to setthis parameter to Disabled if you use other operating systems.To prevent data loss, set this parameter to Auto if you are using a hard diskwith more than 528MB capacity that was previously configured through theLBA mode. If you use a hard disk configured through the user-specificCylinder-Head-Sector (CHS) mode, set this parameter to Disabled.Halt OnThe category determines whether the computer will stop if an error is detectedduring power up.No errors Whenever the BIOS detects a non-fatal errorthe system will be.All errors The system boot will not be stopped for anyerror that may be detected.All, But Keyboard The system boot will not stop for a keyboarderror; it will stop for all other errors.All, But Diskette The system boot will not stop for a disk error; itwill stop for all other errors.All, But Disk/Key The system boot will not stop for a keyboard ordisk error; it will stop for all other errors.
