Parity / ECC in System Programs
  The 85 can emulate ECC using parity SIMMs. This is not worth it. Leave the Memory Detected setting in Change Configuration to "Parity". Go to  "ECC-P"  for more details.
   System memory can be optionally expanded up to 256MB using 32MB Parity SIMMS. 2MB to 32MB Parity SIMMs are supported, INTERLEAVED ONLY. All 256MB are addressable by Direct Memory Access (DMA). SIMMs must be installed in pairs of the same size. speed, and type.

Mixed Memory Sizes in K and N Models
   When a mixture of 4MB, 8MB and 16MB (or larger) SIMMs are installed in the 9585-xKx and -xNx computers, install the larger pairs in the lower numbered connectors (A1/B1 lowest) and the smaller pairs must be installed in the higher-numbered connectors (A4/B4 highest), . 

Parallel Port
   Bidirectional with DMA support. 100KB/s max supported speed.

50 to 68 pin adapter

Can't Use >7 SCSI Devices
From John Poltorak
>So the $64,000 question ... how come your machines can always use 15 devices and mine max out at seven?

From Peter
Q1: which internal cable do you have ? The odd-colored woven double wire cable with 50 pin connectors ? Or the "later" internal Wide-SCSI cable with 68-pin plugs at the device ends ?
Q2: (results from Q1:) which port on the internal adapter are you using ? The 68-pin Molex (black plastic) directly on the board or do you have the Molex-to-50 card-edge converter in between ? If so - the adapter is switched into 8-bit narrow mode and will take only 7 devices. You need to use the 68-pin Molex without the converter to have advantage of the 16-bit Wide mode. If you have the converter attached to the Molex the external port is also run in 8-bit mode as far as I know - and limits the adapter to ... seven devices.
   The planar F/W SCSI on the Server 85 is *similar* to the "3 connector" F/W SCSI adapter /A (8EFC) - but it differs a lot. The F/W card has a separate 50-pin card-edge connector for the internal devices - and using this connector with only "narrow" devices does not afflict the ability to use "Wide" devices on the external port - given that you use a "wide" cable as well. You cannot use an internal narrow cable and external narrow cable as well and hope that you can adress 15 devices with that. This will not work. As soon as you use an 8-bit cable you are cut to 7 devices on the planar F/W.

Remote power-on feature that  allows the server to be powered-on remotely via an external modem, or from an internal timer. Remote power-off can be achieved through software control and is beneficial for running reports or printouts remotely, during off-shift periods.

Unattended start mode The Server 85 433 and 466 models can automatically restart the server after a power failure and resume normal operation, without operator intervention

Vital Product Data (VPD) enabled for unique ID (model/submodel); Type/model/serial number; Planar serial number; Manufacturing ID; Planar FRU number; Planar part number. A system administrator can view from the LAN the PS/2 Server 85 models that reside on the network, including configuration.  This function can also serve as a security measure by confirming if unauthorized servers are connected to the network.

Note: This problem is particularly troublesome because at the first sign of trouble during OS/2 installation, users remark-out (REM) all unneeded drivers in the CONFIG.SYS file; for example, BASEDEV=IBM1*.ADD. This should be a line of action because the PS/2 9585 is a Micro Channel system. However, if the statement BASEDEV=IBM1FLPY.ADD is remarked-out, OS/2 installation will fail with one of the above error messages.
   Make sure the REM in front of BASEDEV=IBM1FLPY.ADD is removed in CONFIG.SYS file. If the line was deleted, restore it. If there are no other problems, the installation will work.

Uh, Maybe Not
  I tried a variety of L2 modules in my N. They all failed (with POD and interposer) until I tried an IDT 256K WB module, 7MP6150. To my suprise, the Cypress OEM PN 06H3306 and PN 06H3307  failed, either jumpered for WB or WT. The failures were a continuous looping reboot, or a black screen (with interposer).
