Command Line Options for
spi8dos.sys (or aspi8u2.sys)
Option
Example
Use
/ccbs
<count>
/ccbs8
Specifies the maximum number of concurrent ASPI com-
mands that can be supported. The valid range is 1 through
16. The default is 4. If you increase this value, the size of the
ASPI manager also increases. Use this option only if you
want to run an ASPI program that specifies a higher number
of concurrent commands.
/d
/d
Displays information about the ARO-1130U2 and attached
SCSI devices when the computer boots.
/L
/L
Enables aspi8dos to recognize all eight possible LUNs
associated with each SCSI ID. If the option is not used,
aspi8dos can recognize only LUN 0 for each SCSI ID.
/m
n
/m1
Causes
aspi8dos to scan the PCI bus. The method used to
scan the bus is determined by the value of
n:
/mb = scan PCI bus using PCI BIOS calls
/m1 = scan PCI bus using Mechanism #1
/m2 = scan PCI bus using Mechanism #2
aspi8dos automatically scans the PCI bus for SCSI devices.
It tries to determine which scanning method will work best
for the given system configuration. Use the /mb, /m1, and /
m2 options only if you want to override the
aspi8dos internal
scanning mechanism. Usually
aspi8dos can determine
which scanning method is optimal for your system. (PCI
BIOS calls are described in the PCI BIOS spec; scanning
mechanisms #1 and #2 are described in the PCI spec.
/norst
/norst
Prevents
aspi8dos from resetting the SCSI bus when you
boot your computer. By default,
aspi8dos resets the SCSI
bus when you boot the computer if the host adapter BIOS is
not present. You can use /norst to prevent this from
happening.
/pause
/pause
Pauses the system after loading
aspi8dos at bootup, so you
can read the message on the screen. After you read the mes-
sage, press any key to resume booting.
/rst
/rst
Forces
aspi8dos to reset the SCSI bus when you boot your
computer. By default,
aspi8dos does not reset the SCSI bus
when you boot your computer if the host adapter BIOS is
present.
/s<
slot number> /s1 /s3
Indicates the slot number(s) where you want
aspi8dos to
look for host adapters. Valid slot numbers = 1 to 15. If you
do not use this option,
aspi8dos scans all slots for host
adapters, beginning at slot 1.
