XVME-976 Adapter Module
3-8
Disconnect
-
When this option is enabled, SCSI targets are allowed to
disconnect from the module if there is a long duration of time for com-
pleting the operation requested. They reconnect later when finished. If
disconnection occurs, the module will issue INT 15 (busy, wait for disk
drive) to allow the host CPU using other software to multi-task. When
this option is disabled, the module will not allow targets to disconnect
and will not issue any INT 15 calls. This option is typically enabled.
I/O Base Address
- This module has 32 registers which require 32 byte
locations in the PC/AT I/O space. There are two options: 340H - 35FH
or 140H - 15FH. The range chosen must not conflict with other system
usage. The range 340 - 35FH is typically chosen.
Interrupt Level
-
This module requires PC/AT interrupt for operation.
Levels 9, 10, 11, or 12 may be chosen. The level chosen must not con-
flict with any other interrupts in the system. Level 10 is typically used
by XVME CPU modules and level 9 is typically used by video control-
lers. Therefore, levels 11 or 12 are good choices.
Diagnostic Messages
If diagnostic messages are enabled, the BIOS will display detailed informa-
tion during the SCSI connection phase. This lengthens the connection phase
as pauses are inserted enabling the user to read the messages. When dis-
abled, no diagnostic information is displayed and the connection phase will
be much quicker. This option is usually enabled during initial system debug,
then disabled after satisfactory operation has been achieved.
When enabled, the following information will be displayed during connec-
tion:
Adaptec header
Jumper configuration information
SCSI device information
Boot progress report
Error messages
When disabled, only the Adaptec header and the error messages will be dis-
played.
Configure the desired diagnostic message option via the switch as described
