I have one 32 and two 16 bit models. The idea is

Where is the IDE and Memory Controller?
On the back. Probably incorporates the memory controller as well.
DC-32 Kingston 1115012, HG62F43S16FL [32-bit mca card!]
DC-16 Kingston 1115015, HG62F43S32FL [16-bit mca card!]
HG62F SERIES (Hitachi CMOS Gate Array) High I/O to Gate Ratio
The DC-32 has a single EPROM, while the DC-16 has two EPROM. This might be related to the HG -16FL and HG -32FL, maybe...

Replacement Drive Cable
If you are like me, you never get all the parts on your adapters... A proper cable is about a 1.5" long with a 40(?) pin connector at each end. It does NOT use a separate Molex power plug.
For Kingston 2MB, 4MB, and 8MB SIMMs,
either jumper position works fine. IBM and Kingston SIMM
modules can be mixed.
(Ed. There seems to be different versions of the DC32, some MAY have W2. Mine does not.)
16-bit Data Card
The DC-16 is also a 16-bit memory
expansion adapter which supports up to 16 MB of onboard
memory. The DataCard-16 can be plugged into any 16-bit
expansion slot, but should use the slot closest to the
fixed disk controller so as not to interfere with any
other expansion slot.
Its onboard hard drive can replace the existing hard disk or be configured as a second hard drive for increased data storage capacity. The DC-16 can also be configured as the boot drive and may be partitioned into several logical drives to run more than one operating system. The DC-16 supports DOS 3.3 or higher, OS/2 2.0 or higher, and Windows NT 3.x.

The DataCard-32 is designed for
IBM PS/2 Models 70, 80 and 90 personal computers. The
models are KTM-DC32/127, DC32/ 209, DC32/260 and
DC32/340. The 2.5" 16ms hard drive sizes are 85MB, 127MB, 209MB, 260MB, 340MB and 540MB.
NOTE: Tim adds support for 85MB and 540MB. Does 540MB imply >528MB support?
The DC-32 is also a 32-bit memory expansion adapter which supports up to 64MB of 80ns Parity onboard memory. The DC-32 can be plugged into any 32-bit expansion slot, but should use the slot closest to the fixed disk controller so as not to interfere with any other expansion slot. It is essentially a Kingston MC/64 (a.k.a. PS/64) adapter with the IDE Interface and HD added.
NOTE: If you need
80nS memory for the PS/64, should you use 80nS in the
It's onboard hard drive can replace the existing hard disk or be configured as a second hard drive for increased data storage capacity.

The DataCard-32 supports DOS 3.3 or higher, OS/2 2.0 or higher, and Windows NT 3.x.
NOTE: Do NOT use 1MB SIMMs (Kingston P/N: KTM1000/M70) other 1MB memory modules; or memory modules that are slower than 85 nanoseconds. These modules are incompatible with the DataCard-32.
Boot feature: (Not
a ADF section! Just a combination key press.)
At this point quickly press Ctrl+Alt+F1. You have only a
few seconds to do so. In the following example, the
internal hard drive is the boot drive and you wish to
boot from the DataCard-32. The screen will now
First drive is original.
Pressing "B" on the keyboard will change
the boot disk from the internal hard drive to the
DataCard-32. If you change your mind, press [Enter] to
bypass, or let the timer count down to zero and it will
boot from the default disk. This procedure will not
permanently change the boot drive default.

In this example, the IBM internal hard drive type is 32. Write down your drive type number below for future reference
For older systems, the 90/95 series would not show Drive Type. Or would it? I don't know.
