The SSD occupies a 8 Kbyte window in the upper memory address
range of D6000 to D7FFF. You should ensure this does not conflict
with any other device's memory address. Jumpers J27 (5-6, 7-8)
control the Flash/ROM disk's memory address. If you select
"Disabled", the disk will not function.
D6000 to D7FFF (default)

These addresses might conflict with the ROM BIOS on some of
your other boards (i.e. PC/104 modules). Read the manuals for
these modules to ensure there is no memory conflict.
Jumpers J27 (1-2, 3-4) control the disk's I/O address. The default is
set to 200~204 but should be set as to not conflict with the I/O
address of other devices. Jumpers are set as shown below:
