Appendix A Flash/ROM disk 45
Formatting the Solid State disk
If you use Flash memory or SRAM, it is advisable to format the
Flash/SRAM disk before copying files to it. The DOS command is
as follows:
FORMAT drv: /U ...
where drv = solid state disk drive A, B, C etc.
File copy utility
The utility program COOKROM.EXE, included on the card's
utility disk, splits the files on a diskette into a series of binary files.
You can then use an external programmer to copy the files to
EPROM or +12 V Flash memory chips. It produces up to three
files, depending on the size of the source files.
Using a memory manager
(EMM386.EXE)
If you are using an extended or expanded memory manager (such
as EMM386 or QEMM386), you will need to configure it to avoid
the addresses used by the Flash/RAM/ROM disk (set by positions
1 and 2 of SW1). Otherwise, the memory manager will attempt to
use these addresses, causing unreliable operation.
For example, the line in your CONFIG.SYS file that invokes
EMM386, the DOS memory manager, might be the following:
DEVICE=EMM386.SYS X=D600-D7FF
This excludes a 8 KB range for the card from D6000 to D7FFF
(the default addresses).
If you are using expanded memory, you will need to make sure
that the memory manager is not putting the page frame in the
disk's addresses. For example,
DEVICE=EMM386.EXE X=D600-D7FF FRAME = D800
You should also make sure that the disk's memory address is not
shadowed in the BIOS.
