Boot device configuration issues

SCSI boot problems

Problems found during the boot(HW) phase of the installation might require certain SCSI drivers to be disabled. To disable a driver at boot time, add disable=driver_name to the bootstring. For example, the following command at the boot prompt restarts the installation and disables the alad SCSI host adapter driver:

restart disable=alad

Disable the driver that corresponds to the init( ) function shown in the following table; init()functions are displayed in the boot hardware listing:
