95A Compatible Complexes
Sorry, folks, but personal experience (supported
with that of others, BTW) proves that running any other
complex but a Type 4
(N, P, Q, or Y) WILL result in a 172 error code. And
that's all you will get. The planar is fine. It just won't
work. Replace the complex with a Type 4 and it will come
up fine...
If you want to earn the IBM badge for your
Scout uniform, the big issue is the lack of planar adfs
for the 95A planar on the Type 1-3 refdisks. If you want
to really impress me, figure it out. I think SC.EXE should
be compatible for all refdisks, since they use a common
diagnostics disk.
JMP 6
Remote Maintenence Processor
If you do NOT have a ServerGuard
adapter installed, this header MUST have a jumper on the
two pins on the right. Otherwise your system will NOT
power up. Also look at JMP6.
and also the power
stuff.
Hacking
an 8595 Case
Yes, you CAN put a 95A planar into a 95
case. Basically, you have to extend the port opening
downward until it's 9 1/16" long. The metal frame port
opening must be extended downward so it's 9 1/16"
long.
First, pull the complex, adapters, power
supply, drives, and planar. Then remove the rear bezel
by removing the 5 hex head screws. The rear bezel will
pivot upwards like the front bezel. Now you can hacksaw
the frame opening downwards. I used a coping saw to cut
across the bottom of the opening.
Do the same to the rear bezel. Take a file
and smooth up the cut edges (or you WILL pay for it
later!). The metal frame has a very thin web left next
to the opening for the power supply. It bent on me when
I tried to bend up a lip for the longer EMC spring on
the planar. Just say the hell with it and cut both sides
of the port opening straight down.
The real difficult part is to put the rear
bezel back on. It SEEMS easy enough. You start by
putting the "hinges" on the top of the pivots at the
back of the case. Now try the delicate ballet of exactly
lining the rear bezel up with the lips on the metal
frame It took me a good 20 minutes. Note the bottom of
the expansion slots has a lip that the rear bezel MUST
fit onto.
I now believe that cutting the frame while the
rear bezel is still screwed on will be the easiest way.
Still clean the fresh edges up with a file. Use
compressed air to blow any metal fragments out.
Put in the new planar. Match up the spring
clip with the lip on the frame. Push forward and pivot
the planar downward onto the lip. Make sure the screw
holes match up- the planar can be too far up or down on
the lip. To adjust the height, pull the planar up and to
the rear. When it comes loose, move it the correct
direction then reseat it.
Y2K Level 1 Compliant
After arduous testing in the Fortress of
Solitude, I have determined THE requirement for Level 1
compliance, and that is the Dallas DS1585S Serialized
RTC. This chip has the required routine to accept the
rollover all by itself. Other MBs that use the older
Dallas DS1285 are Level 2 compliant. (all 90s, all M
class 95s, possibly X class 85s).
IEEE1284
Parallel Port
LPT A (bottom parallel port) is IEEE1284
compliant. It is capable of transfer rates up to 2MB/S.
It is also called Expressprint.
There was a prototype multiplexor for it called the F/MUX. Parallel
Port B (top parallel port) is a standard PS/2
bidirectional port.
Serial Ports
Both DB9 serial ports are capable of
345K/S.
Synchrostream Capable
This planar supports SynchroStream (for
whatever good that does). The design lets both the 32
bit data bus and the 32 bit address bus be used for
sequential data streaming after the initial data address
is sent. Go to Data
Transfers for more info. I haven't seen any
suggestion that any particular OS fully uses
SynchroStream, not even OS/2.
LogicLock
This interesting bit of security
hardware is a mechanical switch that detects if
someone has attempted to open the case without using the
key to unlock it. First, you need to set the
administrator's password. NOTE:
If you forget the administrator's password, you will
have a planar that will not work. There has been some
attempts to replace the DS1285, but that's not the
complete fix. A VPD error keeps occuring. It seems the
password is stored in two locations?
Next you need to set the unathorized access
monitor to "Enabled" under Set Configuration. NOTE: I do not advise you
to set the unauthorized
access
monitor to anything BUT disabled.
I'm still trying to understand WHAT the LL
will do after someone attempts to pry open your 95A
system. It will definately log the attempt. But what
does it do after?
Unattended Start Mode:
Power-On password must be set first.
The use of the unattended start mode ( Also called
"Network Server Mode") on PS/2 systems will disable the
mouse port. This is normal system operation and should not
be considered a defect. Disabling the mouse port is
required to maintain security of the system when using
unattended start mode. IBM's explanation HERE
Power
On Features
The power supply in Server 95 has a
power-on/standby mode. In the standby mode, the
system can be power-on by either of three methods:
the power switch, a wake-up alarm from the real-time
clock, or a start-up signal from serial port A (kickstart
feature). The wake-up alarm and kickstart feature can be
disabled by software (see Extended Control Register B (Hex
4B)).
Wake-On-Time or Wake-up alarm: system powers on when
the time and day matches the alarm bytes.
Wake-On-Ring or Kickstart:
system powers on when serial port A detects incoming
call or data
The system can then be powered-off (standby mode) by
the power switch or by setting the return-to-standby bit
to 1 (see Extended Control Register A (Hex 4A)).
Note From the
standby mode, the power switch must be pressed twice to
turn the power off. When first pressed, the switch
places the power supply in the power-on mode. Wait
about 5 seconds, then press the switch again to place
the system in the standby mode.

Num Lock
Determines how the Num Lock key will be set
when the operating system is started. Please note
that your operating system environment might change the
setting of the Num Lock key. The normal setting of
this feature is <Off>.
<"Off">,

Display F1 Prompt
During startup, your system normally
displays a prompt that tells you to press F1 for access
to the system programs. If you wish to suppress this
prompt, change the setting to <No>.
<"Yes">,
No
Hands-off Configuration
Normally, when you add or remove adapters,
devices, or memory, you provide input to reconfigure the
system. If you change this setting to <Enable>,
the system will attempt a hands-off configuration when
hardware is added or removed. No user input will
be required unless the default values cannot be used.

Unauthorized-Access Monitor
If a privileged-access password (PAP)
is set, the system monitors its covers for evidence of
tampering. If a PAP is set and this feature is set
to <Enabled>, the
system stops if its covers are tampered with. When
the system stops, data in memory waiting to be stored
might be lost. If you
do not want the system to stop when its covers are
tampered with, select <Disabled>
in the 'Change Configuration' window. Note that when you run
the Automatic Configuration program, this feature might
be reset to <Enabled>."
[ed. If you forget
the PAP, you can't change system configuration ever
again. VERY dangerous! Leave DISABLED!!]
