3.26 DiskOnChipAddress Setting

The DiskOnChipfunction allows the system to boot or operate without a FDD or a HDD. DiskOnChipmodules 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 DiskOnChipmodule 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.

When installing a DiskOnChipmodule onto your board, please take note of the following:

1.Orient yourself properly with the location of the DiskOnChipsocket. 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 DiskOnChipmodule. 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.
