Software Guide If you have one or more SCSI hard disks installed in your system, you do not need to enter their specifications here. SCSI drives operate using device drivers and are not supported directly by any current PC BIOS. If your mainboard has the SCSI controller card option, and you will use it, see the SCSI instructions that follow later in this section. If you have some other SCSI controller, follow the instructions that came with it on how to install any required SCSI driver. The are four hard disks listed "Primary Master", "Primary Slave" "Secondary Master" and "Secondary Slave". For each IDE channel, the first device is the 'master' and the second device the 'slave'. To enter the specifications for an MFM or ESDI hard disk drive, you must first select a 'type'. You can select the "User" option and enter the specifications yourself manually or there are 45 predefined drive specifications which you can look through to see if the specifications for your drive are assigned a type number. Do this by using the or key to change the option listed after the drive letter. For an IDE hard drive, you should use the auto-detection utility described later to enter the drive specifications automatically. If you want to do this, leave the drive set to "None". You can enter the specifications yourself manually by using the User option if you want to. There are six categories of information you must enter: "Cyls" (number of cylinders), "Heads" (number of read/write heads), "Precomp" (write precompensation), "LandZ" (landing zone), "Sector" (number of sectors) and "Mode". The "Size" entry is automatically determined by the other specifications. Your hard disk vendor's or system manufacturer's documentation should provide you with the drive specifications. If you have an IDE drive, unless your drive is already formatted with specifications different from those detected by the auto-detection utility, the easiest thing to do is use the autodetection feature to enter the drive specifications. 3- 5
