[. . . ] The IDE CD-ROM is always automatically detected Option 59 IDE channel type The following screens appear if you select the IDE drive parameters: 60 Chapter 4 BIOS Utility Note: A parameter with an asterisk (*) mark indicates that the parameter appears only when you are in the Advanced Level. See "Entering Setup" on page 52 for how to view the advanced level. Parameter Device detection mode Description Lets you specify the type of hard disk installed in your system. If you want BIOS to automatically configure your hard disk, select Auto. If you know your hard disk type, you can enter the setting manually Indicates a hard disk type device Specifies the number of cylinders of your hard disk, and is automatically set depending on your Type parameter setting Specifies the number of heads of your hard disk, and is automatically set depending on your Type parameter setting Specifies the number of sectors of your hard disk, and is automatically set depending on your Type parameter setting Specifies the size of your hard disk, in MB When set to Auto, the BIOS utility automatically detects if the installed hard disk supports the function. If supported, it allows you to use a hard disk with a capacity of more than 528 MB. This is made possible through the Logical Block Address (LBA) mode translation. However, this enhanced IDE feature works only under DOS, Windows 3. x, Windows 95, Windows 98, Windows NT 3. 5 and above, and Windows 2000. Other operating systems require this parameter to be set to Disabled. User Input Option Auto User None Device Type Cylinder Head User Input Sector User Input Size Hard Disk LB Mode User Input Auto Disabled 61 Parameter Hard Disk Block Mode Description Enhances disk performance depending on the hard disk in use. If you set this parameter to Auto, the BIOS utility automatically detects if the installed hard disk drive suports the Block Mode function. If supported, it allows data transfer in blocks (multiple sectors) at a rate of 256 bytes per cycle. Improves system performance by allowing the use of the 32-bit hard disk access. This enhanced IDE feature works only under DOS, Windows 3. x, Windows 95, Windows 98, Windows NT, Windows 2000, and Novell NetWare. If your software or hard disk does not support this function, set this parameter to Disabled. When set to Auto, the BIOS utility automatically detects if the installed hard disk supports the function. If supported, it allows for faster data recovery and read/write timing that reduces hard disk activity time. This results in better hard disk performance. To disregard the feature, change the setting to Disabled. The Ultra DMA and Multi-DMA modes enhance hard disk performance by increasing the transfer rate. However, besides enabling these features in the BIOS Setup, both the Ultra DMA and MultiDMA modes require the DMA driver to be loaded.

Selecting this option displays the following screen: The following table describes the parameters in this screen. Parameter Serial port 1 Description Enables or disables serial port 1 Option Enabled Disabled Base address Sets the I/O base address of serial port 1 3F8h 2F8h 3E8h 2E8h IRQ Sets the IRQ (interrupt request) channel o serial port 1 4 11 63 Parameter Serial Port 2 Description Enables or disables serial port 2 Option Disabled Enabled 2F8h 3E8h 2E8h 3 10 Enabled Disabled 378h 278h Base Address Sets the serial port 2 I/O base address IRQ Sets the IRQ channel of serial port 2 Parallel Port Enables or disables the parallel port Base Address Sets a logical base address for the parallel port. [. . . ] Verify that the SCSI controller and the SCSI devices are properly configured and installed. Be sure to cycle the power OFF and ON after changing any values on a SCSI controller, in a Setup program, or on a SCSI device. Doing this ensures that the new initial values are loaded. Be sure that the SCSI bus is properly terminated. [. . . ]
