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/ROM disk (set by jumpers J30 and
J31). 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.
User's Note: Sometimes, it is better to assign the sectors and tracks
when formatting an SSD. For different disk sizes, you must use
different assignments, for example:
Format drive :/u/n:9/t:40
Format drive :/u/n:18/t:80
( drive is the disk label, such as A or B)
After formatting, please read the on-screen message carefully. DOS
will provide information on total and available disk space, bad
sectors, etc. If the disk size does not match your assignment,
please check the system settings again, such as the switches and
jumpers. If you need a bootable disk, you should do the system
transfer by typing:
SYS drive
