PCD1/2 REV B SPECIFICATION      (C) MVS 1996




DESCRIPTION
-----------

The PCD1 has an IDE drive interface and works with ATA compatible PCMCIA,
Compact FLASH, or Hard Disks.  Since the PCD1 interfaces at the BIOS level
all operating systems are supported and can boot from the PCD1.  It is also
available with 8-bit ISA (PCD1a) and PC104 (PCD1b) to allow use of PC
compatible removeable media with MVS SBC controllers.  A "STAMP DRIVE"
model (SDRV1) works with any controller, big or small, with a serial port.

The PCD2 dual slot AT type 16-bit ISA adapter is for use with motherboards
running DOS or Windows.  RAM up to 64mbyte, ATA FLASH up to 1 gigabyte, and
many I/O cards are supported.  Convenient pushbutton ejector mechanisms
allow easy extraction of cards for removeable media applications.

Both cards work with the newer "Compact Flash" type cards with an
appropriate adapter.  This is usually included with the card, camera, or
palmtop or can be purchased separately.  The thinner and somewhat less
expensive "Smart Card" type memory is also supported with an adapter.




PCD1 INSTALLATION
-----------------

Plug the PCD1 into any open IDE connector taking care to match pin 1 on the
card (near power connector) with pin 1 on the cable (colored edge).  Next
Plug a floppy power connector into the card, again taking care to match pin
1 (near edge of card) with the cable pin 1 (red wire).  To set the card for
master short the jumper otherwise the card will be slave.  Most
motherboards use "auto" settings to detect card size so usually nothing
else needs to be done except FDISK and FORMAT like a normal hard drive.




PCD2 INSTALLATION
-----------------

PCD2 runs without drivers under Windows 98 and with a driver (PCD2.BIN)
under DOS.  The DOS driver is very compact and takes about 1/10th the
memory of more common "socket services" type drivers.  To install:

 in CONFIG.SYS use "devicehigh=pcd2.bin /ac800 /p1" for outer slot 
               use "devicehigh=pcd2.bin /acc00 /p0" for inner slot 
               or put both lines in for 2 slots.

It may be necessary to exclude the "/axxxx" address segment in BIOS and
with EMM386.EXE.  If used with ATI All-In-Wonder capture card under DOS
it may be necessary to reconfigure the ATI card due to address conflicts.
