NAME

fload − initialize the Sky floating point processor

SYNOPSIS

/etc/fload

DESCRIPTION

Fload is run when the IRIS workstation is booted.  It probes for the Sky floating point processor.  If the processor is found, it is initialized and its microcode loaded from the file /lib/skyffp.fas . 

The program can be run by the superuser under normal operating conditions.  Since fload does not access the board through the normal kernel utilities, any users of the board may be aborted when the program is run. 

DIAGNOSTICS

If fload is run by a user who is not the superuser, the message

          fload: phys call failed

will be given. 

If fload cannot access its microcode file (/lib/skyffp.fas), it will complain. 

If the Sky board is not visible in the system, i.e., either it has not been installed or is installed incorrectly, the message

          fload: skyffp not installed

will be displayed. 

Fload does some cursory testing of the board.  If one of these tests fails, one of the messages

          fload: error initializing skyffp
          fload: board test failure
          fload: board function test failure

will be displayed.  In either of these cases, the board should be replaced.
