Instruction manual

The FAST_SCSI_A and FAST_SCSI_B environment variables initialize the
SCSI controllers. The variable FAST_SCSI_A is for bus A devices and FAST_
SCSI_B is for bus B devices. When the fast SCSI devices are connected
and FAST_SCSI_A/B is set to on, the SCSI firmware will operate in fast
SCSI mode. If both slow and fast SCSI devices are connected to the same
bus and the FAST_SCSI_A/B environment variable is on, the firmware will
differentiate between devices.
Note that the recommended maximum bus length is 4 meters for slow SCSI
devices and 3 meters for fast SCSI devices. When these limits are exceeded,
the SCSI bus is likely to have errors. If your total bus length, including
internal and external cables, is greater than 3 meters, you must set the
FAST_SCSI_A/B environment variable for that bus to off.
The accepted values are:
ON Operate in slow and fast SCSI modes, device dependent.
OFF Operate in slow SCSI mode.
The default settings for FAST_SCSI_A and FAST_SCSI_B environment
variables are off. Therefore, the SCSI controllers will be initialized to operate
in slow SCSI mode.
• LANGUAGE
Set the console keyboard layout to one of the sixteen supported languages. If
the system is not a workstation, this command is ignored and an appropriate
