3.26 DiskOnChip
Address Setting
The DiskOnChip
function allows the system to boot or operate
without a FDD or a HDD. DiskOnChip modules may be formatted as
drive C. With DiskOnChip
, user may also execute DOS commands
such as FORMAT, SYS, COPY, XCOPY, DISCOPY, DISKCOMP, etc.
The U31 location onboard the HS-6038 is the DiskOnChip module
socket. If you have another memory device that has a similar memory
capacity with that of the DOC in your system, please set both at
different memory address mapping to avoid mapping area conflicts.
Failing to do so will not make the HS-6038 and the additional memory
device function properly. JP6/JP7 selects the starting memory address
of the DiskOnChip (D.O.C.) to avoid the mapping area with any other
memory devices.

3.26.1 Installing DiskOnChip Modules
When installing a DiskOnChip module onto your board, please take
note of the following:
1. Orient yourself properly with the location of the DiskOnChip
socket. Try to locate the pin 1 location on your socket. Pin
numbers are usually printed on either the component side or the
solder side of your board.
2. Locate the Pin 1 location on your DiskOnChip
module. More
often than not, Pin 1 can be found on the lower right corner of
the chip. Please refer to the diagram for the exact location.
3. Once you have figured out where the pin 1 locations are (on
both chip and socket), align the module’s pins on an upright
angle against the socket. Using both thumbs, gently press the
module into the socket until all the pins are secured to their
designations.
