SCO UNIX BOOT FAILURE WITH MEMORY EXPANSION BOARD
|
|
|
|
|
|
PROBLEM: Under SCO UNIX 3.2 version 2.0, system will hang
|
|
intermittently during boot if memory expansion board is
|
|
present, AST part number 202387-001.
|
|
|
|
AFFECTED
|
|
SYSTEM BOARDS: All system boards with the following part numbers:
|
|
|
|
202356-004 and 202360-001
|
|
|
|
CAUSE: During UNIX installation the software will check for known
|
|
devices and will activate a driver for that device. UNIX
|
|
mistakenly identifies a device that is not present, and
|
|
activates a driver for it. This causes the system to hang,
|
|
with the following error message:
|
|
|
|
WDHA-OUT: command byte 01 rejected
|
|
WDHA-OUT: command byte 07 rejected
|
|
|
|
SOLUTION: The new release of SCO UNIX 3.2 version 3.0 resolves this
|
|
problem and is scheduled to be released by SCO in July,
|
|
1991.
|
|
|
|
NOTE: A temporary solution would be to slow the system down
|
|
during the boot process, and resume normal speed after
|
|
completion of boot sequence, which would be the login
|
|
prompt. This can be accomplished by using the <CTRL>
|
|
<ALT> <DOWN ARROW> and <CTRL> <ALT> <UP ARROW>
|
|
sequence. For further information on speed commands,
|
|
please refer to your systems user manual.
