Configuring the SCSI Bus Host SCSI ID Scan Order Removable Media Support CHS Mapping NOTE In general it is not advisable to change your host adapter ID from the default value of 7, as this gives it the highest priority on the SCSI bus. However, if you have two adapters sharing the same SCSI devices, you should give one of the adapters a currently-unassigned ID to avoid duplication of SCSI IDs. This option lets you tell the host adapter BIOS and your device drivers to scan the SCSI bus from low to high (0 to max) SCSI ID, or from high to low (max to 0) SCSI ID. If you have more than one device on a SCSI bus, changing the device order changes the drive letters which are assigned to them by the system. This will change the boot order. Only used when removable disk drives are installed. For more information, refer to the User's Guide that came with you removable disk drive. This option defines the cylinder head sector (CHS) values that are mapped onto an un-partitioned disk. SCSI Plug and Play Mapping is the default setting. For full compatibility with other SCSI adapters CHS mapping should be set to Alternate CHS Mapping. The SCSI Plug and Play Mapping and Alternate CHS Mapping options will not work if the hard disk has been partitioned using FDISK. To remove partitioning reformat your hard disk using either the Format Disk option or the FDISK /MBR command at a DOS prompt. To complete the reformat, you will need to restart your PC Workstation.
