PCMCIA /A

Note: If your PCMCIA Reader suddenly refuses to read / write, and you have been pulling it out / reinserting it a bit, one of the SMD capacitors (white ceramic caps) might have had a solder joint fail. Check the solder joints carefully, look for a "fracture". I resoldered one, and restored my reader to life... 

J1 and J2 are HPDB68 pin connectors, identical to those used on Fast/Wide drives. The cable is 68 pin .025 pitch. 

My Reader has a slightly different chip layout, but the SMD capacitors, the oscillator, controller, and the J1 / J2 connectors are in the same place.

C1-C2: 47uF 16V
C3: 22uF  16V

Curses. This makes my PCMCIA outline look poor. I'll fix it by removing all of Tatsuo's outlines from my site...



If you are using OS/2 version 3, install the ThinkPad 720 PCMCIA drivers... The PS/2 E is an ISA machine... Duh! 

NOTE: An OPTIONS BY IBM HARDWARE MAINTENANCE MANUAL SUPPLEMENT (S83G-9902, 83G9902) is available in support of this product.
  These adapters come with the brackets required to install them into the special bay in the new IBM systems (6875 and 6885) or a standard 3.5-inch drive bay.  Installation in a 5.25-inch drive bay requires the use of a standard 3.5-inch to 5.25-inch drive bay conversion kit (70G8165).

   I purchased one of these a while ago for a project I was working on and had it installed in my 8595.  It did, indeed, work great under DOS/Win and OS/2 Warp.  Problem is that the adaptor uses the "stinger" chipset which is the same as what IBM used in the ThinkPad 720 series.  This chipset is
unsupported in Win9x and, if memory serves, you can only use the real mode drivers and not have any 32-bit support.  Tis a bummer.
Editor's Note: NT 4.0 will not even SEE it.



Half-Assed W95 Support
From the god-Emperor of Microchannel 
  Well, I am reporting "success" with the Stinger under W95. I got a mixed result that you all might accept- Install Ezplay. When it complains about not being able to rename config.pcm to config.sys, hit OK. Fire up Exploiter and save c:\ezplay\config.pcm as c:\config.sys
   Now open up c:\windows\ios.ini and add "diskdrv.sys" to the area with
the rest of the IBM PCMCIA drivers. Reboot. 
    Results- you will be able to use your hard drives in protected mode. The two PCMCIA slots and your CD Rom will be in compatibility mode. You got to suffer a little bit...
   The problem seems to be when IOS tries to issue Int 25 commands to the
PCMCIA and CD. The diskdrv.sys is the crux of the matter. Look in
IOS.LOG for errors.
   I tried must_chain, non_disk, monolithic. I got the same results with
just the diskdrv.sys entry, so I just left it that way. I'm not totally sure what this will do with communications and network PC cards. It worked with my 105MB PCMCIA HD. YMMD


95 Bezel Hack
   Got tired of the dorky look of a bare B: drive bay. Did some measurements and started cutting. Basically, you cut the bottom of the PCMCIA opening flush with the bottom of the horizontal angle of the blank floppy cover.
   Measure 1.5" from the left and right edges of the floppy bezel. Those
are the edges of the left and right side of the opening. I am still fighting with the top edge of the opening. .43" was too low. Much easier to cut excess away than put it back....

More Refined 95 Bezel "Hack"
Tom Webster quit doing one arm pushups long enough to type:
   Installation on a Model 95 is quite simple.  Use a QIC Tape Drive bezel, IBM part number 34F2719 (ASM 34F2721), and add four 0.156 inch high, 0.127 ID, 0.25 (or there abouts) OD spacers, or equivilent stack of number 4 flat washers, between the 'drive' and the skid. 
   This centers the 'drive' vertically in the bezel opening with ample clearence to insert/remove the PCMCIA cards. NO BEZEL HACKING REQUIRED. (Ed. What fun is that?)

Preparing this Adapter for Use
      Having successfully installed this option into the computer, you are now ready to plug PCMCIA cards into it. This adapter allows the HOT PLUGGING and REMOVAL of PCMCIA cards Depending on the PCMCIA card that you choose to use, you may be required to install the drivers which were supplied with that card.



Troubleshooting
Adapter does not operate
        1. Confirm logic card is installed correctly in computer's 16-Bit slot.
        2. Confirm bay card is installed correctly in a 3.5 or 5.25 Inch bay.
        3. Confirm that device drivers and support software have been installed and are operational. You will see a response from these drivers during the power on or  re-booting sequence. (Ed. Use F8 during boot to do a step-by-step confirmation under Doze/W95)

PCMCIA card does not operate in a slot
        1. Make sure that the card is completely inserted in the slot. There will be an audible  beep when the card is properly inserted or removed.
        2. Make sure that the device drivers for the PCMCIA card have been installed in this computer.

PCMCIA card does not operate in either port
        1. Confirm cables are plugged according to instructions.
        2. Confirm bay card is installed in 3.5 or 5.25 Inch bay 

Error message Invalid Drive Letter appears.
      This may occur if the host computer has assigned drive letters above C: for devices such as a CD ROM, additional hard disk or partitioned hard drives.

      Insert the following statement in the CONFIG.SYS before any device driver statements: lastdrive = # where # equals the letter of the last drive in the system. You must include two letters for the adapter and letters for all of the previously configured drives.

      DOS Configuration Example

      DEVICE=C:\WINDOWS\HIMEM.SYS
      FILES=30
      BUFFERS=30
      DOS=HIGH,umb

      DEVICE=C:\EZPLAY\AUTODRV.SYS C:\EZPLAY\AUTODRV.INI
      DEVICE=C:\EZPLAY\DISKDRV.SYS



The CONFIG.SYS File

DOS CONFIG.SYS
The installation program modifies the DOS CONFIG.SYS file to include the appropriate DEVICE statements in the following order.

   DEVICE=x   The letter x specifies the Socket Services already installed on the computer.
   DEVICE=y   The letter x specifies the Socket Services already installed on the computer.
   DEVICE=[drive:][path] PCMATADD.SYS /baseslot=n /stbtime=n
 where:
   [drive:][path] The parameters [drive:][path] specify the location of the device driver file.

   /baseslot=n    This option sets the base slot address, where n specifies whether the address begins at (0) or (1).  The default is 1. Set this switch to 0 only if you have a problem addressing the slots. If a value other than 0 or 1 is specified, this switch is ignored and the default setting is restored.

   /stbtime=n     This option enables the standby mode, where n specifies the number of minutes that will elapse before the card goes to standby mode. The minimum value is 5 minutes, the maximum is 20 minutes. If  a value greater than 20 is specified, this switch is ignored. All sockets are effected when you set this switch. (This feature does not support solid state cards.)

OS/2 CONFIG.SYS file sequence
The installation program places the appropriate device statements in the OS/2 CONFIG.SYS file. They MUST appear in the following order. 

   BASEDEV=OS2DASD.DMD 
   DEVICE=C:\OS2\xxxxxx.SYS      (the Card Services statement) 
   DEVICE=C:\OS2\PCMATAE.SYS 
   DEVICE=C:\OS2\xxxxxxxx.SYS    (the Socket Services statement) 
    BASEDEV=PCM2ATA.ADD 
   BASEDEV=OS2PCARD.DMD (Note... Card and Socket Services are not supplied with this option) 

switch options for the main device driver
   BASEDEV=PCM2ATA.ADD [/s:n] [/i:m] [/stbtime:n] [/b] where: 

   /s:n        This option recognizes the PCMCIA sockets, where n specifies the number of physical PCMCIA sockets available. The default is 2 sockets, the maximum is 4 sockets. 

   /i:m        This option ignores specific PCMCIA sockets, where m specifies the logical socket number to be ignored. Multiple settings are allowed. This feature is useful when a Type III card physically occupies two sockets. 
                 Examples: 
                 BASEDEV=PCM2ATA.ADD /i:1  (First socket is ignored) 
                 BASEDEV=PCM2ATA.ADD /s:4 /i:2 /i:3  (Second and third sockets are ignored) 

   /stbtime:n  This option enables the standby mode.  (Same as described above for DOS stbtime option) 

   /b          This option specifies the OS/2 operating system to start  (boot) from the PCMCIA-ATA card. If you specify this option, then PCMCIA.ADD module decreases the number of  sockets specified by the /s switch because the startup  PCMCIA-ATA card is treated as an internal IDE hard disk, not a PCMCIA-ATA card. When the OS/2 operating system starts (boots) from the PCMCIA-ATA card, if you use the /s:4 option w/o the /b option, the disk assigned to the last drive-letter will not be assigned to any physical socket. (To make this PC Card a bootable PC Card, see the documentation that came with the OS/2 operating system.) 

Notes About the /b Option 
   1. Do not ignore the computer startup socket by the /i option when you use the /b option.  Because the PCM2ATA.ADD module cannot  examine whether or not the socket can start the operating  system, the PCM2ATA.ADD module decreases the number of supported sockets by the /b option and  subtracts the number of sockets to be ignored. For example, when you add the /s:4 /b /i:2  options to the PCM2ATA.ADD module, and the OS/2 operating system is started from socket 2, the  PCM2ATA.ADD module can manage only two sockets. Sockets 1 and 3 are assigned and socket 4 is ignored. 
   2. This switch option applies only to the CONFIG.SYS file residing on the PC Card. Do not specify  this option on the CONFIG.SYS file that resides on the internal hard disk drive.
   3. If you started (booted) from the PC Card, do not remove the card until you shut down the  operating system. 



PCMCIA Cards
         There are three types of PCMCIA cards, arraigned by size. The function of each type is only restricted by its size. 
       Type I  -3.3mm thick SRAM or EEPROM memory cards. 
       Type II -5.0mm thick cards that allow more complex functions than the Type I cards. Type II PCMCIA cards include SCSI adapters, sound cards, modems, network adapters, and interface cards for external devices 
       Type III -10.5mm thick cards that are most often hard drives. 

Software Drivers:
    There are several layers of software drivers that allow the PCMCIA card and slot to function with the computer. These software drivers allow the applications and user to make use of the PCMCIA hardware. Which drivers are needed depends on the card, and the drivers used. 
Card Services Card Services works with the operating system to allocates memory, interrupts and other system resources to the card and drivers. 
     PCMCS.EXE Phoenix DOS Card Services 
     IBMDOSCS.SYS Yamato (IBM) DOS Card Services 
     PCMCIA.SYS OS/2 2.1 Card Services 

Socket Services 
    Socket Services provides a low level interface for the socket hardware. Socket Services accepts configuration information from Card Services, and reads low level card configuration data from the PCMCIA card. 
     PCMSS Phoenix Socket Services 
     IBMDSS01.SYS Yamato (IBM) AT bus DOS Socket Services 
     IBMDSS02.SYS Yamato (IBM) MCA Socket Services 
     IBM2SS01.SYS Yamato (IBM) AT bus OS/2 Socket Services 

Client and Super Client Enablers
  Client Enablers can configure one specific card for use as a standard peripheral device. A Client Enabler is specific to the card it is written for, and works the same as a driver for that device. Super Client Enablers have the ability to recognize and configure a wider range of cards (two or more). 
                    ESTDFM.EXE IBM Modem Client Enabler 
                    MEGAHZ.EXE Megahertz modem Client Enabler 
                    PCMSCD.EXE Phoenix Super Client Driver 
                    AUTODRV.SYS Yamato Super Client Driver 

Point Enablers 
     Point Enablers bypass Socket and (or) Card services and function as a Client Enabler. Point Enablers can save memory if one is available for the card, and matches the socket controller. Point Enablers will usually not work with each other, or other PCMCIA drivers. (There are no universal Point Enablers! Each is designed for a specific card, and must be provided by the manufacturer.) 

Other Drivers
           Some sets of PCMCIA drivers have additional drivers or utilities that take care of one part or another of the complete job. Some PCMCIA drivers, like the IBM-Yamato drivers, require POWER.EXE to be loaded before any of the PCMCIA drivers. The IBM drivers also have a Resource Map Utility that lets you tell the drivers which part of the excluded memory to use; 
                    DICRMU01.SYS ISA Resource Map Utility (IBM) 
                    DICRMU02.SYS MCA Resource Map Utility (IBM)

"Universal" PCMCIA Drivers 
   ThinkPad 350, 360, 510, 720, 750, 755, and PS/Note 425 all have compatible hardware. These models can use the Yamato PCMCIA drivers with EasyPlay. The file TPPCMCIA.EXE, will create an install disk for the Yamato drivers and EasyPlay. The file can be downloaded from the Internet. 

Card Memory Requirements 
           PCMCIA Card Services requires 4K to load and function. Some PCMCIA cards will not make any other  requirements, but some do. Modems and most memory cards do not need any more memory. The memory that is needed has to be set aside in the CONFIG.SYS file. To exclude 4K for Card Services, the EMM386 line may look like this: 
                 DEVICE=C:\DOS\EMM386.EXE X=B000-BFFF 
      For a system with an IBM Ethernet PCMCIA adapter, 16K  needs to be set aside; 
                  DEVICE=C:\DOS\EMM386.EXE X=D400-D7FF 
    The exclude range will need to be increased if a PCMCIA card is installed that needs more memory  reserved for it. Here are some of the common memory requirements that would need to be added to 
                    Card Services 4K; 
                    IBM Token Ring card 16K RAM + 8K ROM = 24K 
                    IBM Ethernet = 16K 
                    IBM 3270 card = 8K
