1230 Symbios SCSI Scripts
RAM test
Performs a simple data
equals address pattern test
of the SCRIPT RAM.
1240 Symbios SCSI
Interrupt test
Copies a simple SCRIPTS
instruction to SCRIPTS RAM
on the Symbios controller. The
SCRIPTS instruction is a
simple INT opcode which,
when executed by the Symbios
chip, should cause a DMA
interrupt to be logged. The
DSP register of the Symbios
chip is set to point to the
instruction and the ISTAT
register is polled until the
interrupt is detected or the
allotted time has elapsed.
1250 Symbios SCSI DMA
engine test
Writes a simple SCRIPT to
Symbios SCRIPTS RAM
which contains a MEM MOVE
opcode. SCRIPT copies 256
bytes from one section of
SCRIPTS RAM to another
SCRIPTS RAM area. Once the
SCRIPT has completed, the
test veriļ¬es that the original
block of data was copied to the
destination area.
