Using a CD-ROM Drive Command Line Options for spi8dos.sys (or aspi8u2.sys) Option /ccbs /d /L /mn /norst /pause /rst /s Example /ccbs8 /d /L /m1 /norst /pause /rst /s1 /s3 Use Specifies the maximum number of concurrent ASPI commands 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. Displays information about the AAA-131U2/133U2 and attached SCSI devices when the computer boots. 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. 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. 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. Pauses the system after loading aspi8dos at bootup, so you can read the message on the screen. After you read the message, press any key to resume booting. 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. 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. C-3

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 AAA-131U2/133U2 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
message, 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.
