F/W SCSI Adapter Firmware Upgrade 7.1
BIOS Upgrade- I have seen mention of a flash disk "F5JW15UK" for the K and N models. Can't find it. If you have a copy, or heard of this file, send me a NOTE

Can I use the Reference v 1.31 on the -xXx?
   Another word for the BIOS: Once you'd put the inappropriate version of the Reference / Diags on an 85 and start for example OS/2 ... you could see really odd effects. Putting the 1.31 code from the -xNx on a -xXx result in a "speed cursor": a fast flashing icon on PM and you cannot click that fast to do anything with the machine anymore with using the mouse. You need to shutdown the beast over the keyboard. The xxx.BIO files differ - and these set the onboard timers to false base values. I had that in '92 or '93 when customers complained about inability to use their machines after "an update". They used the 1.31 "just because it was there and had a higher revision number". Without thinking and reading the DOCs as it seemed. 

Power Supply
9585 power supply is 288 watt The 9585 DOES NOT have a side fan.

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.

32-bit, 16.5 MHz DMA, Vital Product Data, System Control Block and 

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.

Fast\Wide SCSI
   The IBM SCSI-2 Fast/Wide busmaster controller is integrated on the system board. It uses the same chipset as the Fast/Wide SCSI. 40MB/s Data Streaming to MCA bus (32 bit), 20 MB/sec on SCSI bus (16 bit).

50 to 68 pin adapter
  A 50 pin cardedge to a female 68 pin half pitch centronics is FRU61G3594. The female 68 pin socket is an AMP part.

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.

Enhanced security -- the Server 85 433 and 466 with LogicLock and new tamper-evident, locking covers, Privileged Access Password, selectable drive startup and support for optional features (such as, the new Cable Cover 4 and the Enhanced 2.88MB 3.5-inch Diskette Drive with electronic eject) provide system security exceeding C2 enabling requirements.

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.

Problems Installing OS/2 on 9585 Computer (HERE)
From Joltin' Joe Kovacs
One of the following error messages is displayed at Diskette 1 while installing OS/2 on an IBM PS/2 9585 computer:
   * OS/2 Warp: OS/2 is unable to operate your hard disk or diskette drive.
   * OS/2 2.x:  The system cannot find the file 'A:\COUNTRY.SYS'. 
The diskette-drive light stays on, and pressing Ctrl+Alt+Del has no effect. The system must be turned off and then turned back on.

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.

L2 Cache
0Kx models have 128kb L2 write back cache.0Nx models have 256kb L2 write back cache.
Both use the same cache modules as the 76/77 Lacuna planars.

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).

0Kx and 0Nx models are also:
     1)  Intel Pentium Overdrive upgradable (socket is 19x19 LIF)
         NOTE: The CPU socket is right behind Bay #3. The original DX2-66 in my 85 had about 3/8ths of an inch of the heatsink fins milled off on the left side of the 486. If you use a POD (like me) be cautious of trying to ram a 5.25 inch drive or CD into that bay.... "It won't fit! @%#&!!!  Bam! Bam! Crunch!" 
  Without the interposer, the POD does not tolerate any of the L2 cache modules I have, either IDT or Cypress (IBM). I had to take out the cache...The interposer looks like THIS  Details how to make your own are there, too...
     2)  SurePath BIOS, upgradeable via "FLASH" EPROM (IBM never released an upgraded BIOS.... My ONG has BIOS 00)
     3)  SCSI-2 F/W adapter (Oh yeah baby! Oh, behave!)
     4)  capable of 256MB of systemboard RAM (I don't have any 16MB SIMMs to verify this)
